Whenever a commit is selected in the graph pane, its SHA1 is
automatically put into the selection buffer for cut and paste.
However, some users may find this behavior annoying since it can
overwrite something they actually wanted to keep in the buffer.
This makes the behavior optional under the name "Auto-select SHA1",
but continues to default to "on".

This allows gitk to be used to display a different set of refs each
the display is refreshed. This is useful when gitk is called from
other porcelain suites, for doing such things as displaying the set of
patches in a patch stack.
The user specifies a command as the argument to the --argscmd option.
The command is run initially and each time the display is refreshed,
and is expected to generate a list of commit IDs, one per line. Those
commits are appended to the commits passed on the command-line when
constructing the git log command to be executed.
The command is considered to be an attribute of a view, and has its
own field in the saved view, and an edit field in the view editor.

Since we limit the rate at which we do updates to the canvas scrolling
regions, it's possible to get into selectline for a row that is
outside the currently-set scrolling region. When this happens,
selectline can't scroll to show the selected line, and as a
consequence, drawvisible chooses some other bogus row to be the
target row.
This fixes it by calling setcanvscroll from selectline in this case.
We also set selectedline (and currentid) before calling drawvisible
so that drawvisible makes the right choice of target row.

First, insertfakerow and removefakerow weren't updating vrowmod,
and hence displayorder was not getting updated when it needed to,
in the case where the fake row was being inserted into or removed
from the last arc. The comparison of varctok vs vtokmod was moved
into modify_arc for these cases (and for the call in rewrite_commit)
to avoid duplicating the extra code needed. Second, the logic in
update_arcrows didn't end up truncating displayorder and unsetting
cached_commitrow if the first modified row was in the last arc.
This fixes these problems.

Previously we passed the arguments indicating what commits the user
wants to view through git rev-parse to get a list of IDs (positive and
negative), then gave that to git log. This had a couple of problems,
notably that --merge and --left-right didn't get handled properly.
Instead we now just pass the original arguments to git log. When doing
an update, we append --not followed by the list of commits we have seen
that have no children, since we have got (or will get) their ancestors
from the first git log. If the first git log isn't finished yet, we
might get some duplicates from the second git log, but that doesn't
cause any problem.

Occasionally the target row stuff would scroll the display to some
uninteresting commit while reading. There were two problems: one
was that drawvisible would set targetrow even if there was no target
previously and no row selected, and the other was that it was possible
for the target row to get pushed down past numcommits, if drawvisible
was called after rows were added but before layoutmore got run.
The first problem is fixed by just not setting targetrow/id unless
there is a selected row or they were set previously.
The second problem is fixed by updating numcommits immediately new
rows are added. This leads to a simplification of layoutmore and
chewcommits but also means that some of the things that were done in
layoutmore now need to be done elsewhere, since layoutmore can no
longer use numcommits to know how much it has seen previously.
Hence the changes to getcommits, initlayout and setcanvscroll.

When updating the graph, gitk uses a git log command with commit
limiting in order to get just the new commits. When path limiting
is also in effect, git log rewrites the parents of the commits it
outputs in order to represent just the subgraph that modifies the
listed paths, but it doesn't rewrite the parents on the boundary
of the graph. The result is that when updating, git log does not
give gitk the information about where the new commits join in to
the existing graph.
This solves the problem by explicitly rewriting boundary parents
when updating. If we are updating and are doing path limiting,
then when gitk finds an unlisted commit (one where git log puts a
"-" in front of the commit ID to indicate that it isn't actually
part of the graph), then gitk will execute:
git rev-list --first-parent --max-count=1 $id -- paths...
which returns the first ancestor that affects the listed paths.
(Currently gitk executes this synchronously; it could do it
asynchronously, which would be more complex but would avoid the
possibility of the UI freezing up if git rev-list takes a long time.)
Then, if the result is a commit that we know about, we rewrite the
parents of the children of the original commit to point to the new
commit. That is mostly a matter of adjusting the parents and children
arrays and calling fix_reversal to fix up the graph.

This fixes a bug in updating the graph after we have cherry-picked
a commit in gitk and then added some new stuff externally. First,
we weren't updating viewincl with the new head added by the cherry-
pick. Secondly, getcommitlines was doing bad things if it saw a
commit that was already in the graph (was already in an arc). This
fixes both things. If getcommitlines sees a commit that is already
in the graph, it ignores it unless it was not listed before and is
listed now. In that case it doesn't assign it a new arc now, and
doesn't re-add the commit to its arc.

Ignoring space changes can be helpful. For example, a commit
claims to only reformat source code and you quickly want to
verify if this claim is true. Or a commit accidentally changes
code formatting and you want to focus on the real changes.
In such cases a button to toggle of whitespace changes would be
quite handy. You could quickly toggle between seeing and
ignoring whitespace changes.
This commit adds such a checkbutton right above the diff view.
However, in general it is a good thing to see whitespace changes
and therefore the state of the checkbutton is not saved. For
example, space changes might happen unintentionally. But they are
real changes yielding different sha1s for the blobs involved.

The make_disporder function has an optimization where it assumed that
if displayorder was already long enough and the first entry in it for
a particular arc was non-null, then the whole arc was present. This
turns out not to be true in some circumstances, since we can add a
commit to an arc (which truncates displayorder to the previous end of
that arc), then call make_disporder for later arcs (which will pad
displayorder with null elements), then call make_disporder for the
first arc - which won't update the null elements.
This fixes it by changing the optimization to check the last element
for the arc instead of the first.

Since commits come in out of order and get sorted as we see them,
we can have commits coming in and being placed before the commits
that are visible in the graph display pane. Previously we just
displayed a certain range of row numbers, meaning that when
incoming commits were placed before the displayed range, the
displayed commits were displaced downwards. This makes it so
that we keep the same set of commits displayed, unless the user
explicitly scrolls the pane, in which case it scrolls as expected.
We do this by having a "target" commit which we try to keep in the
same visible position. If commits have come in before it we scroll
the canvases by the number of rows that it has moved in the display
order.
This also fixes a bug in rowofcommit where it would test
cached_commitrow before possibly calling update_arcrows, which is
where cached_commitrow gets invalidated if things have changed.
Now we call update_arcrows if necessary first.

This restores date mode, which lists commits by date, as far as possible
given the constraint that parents come after all their children. To
implement this in the new framework, we (1) only join a new commit onto
an existing arc if the arc is the last arc created, (2) treat arcs as
seeds unless they have a child arc that comes later, and (3) never
decrease the token value for an arc.
This means we get lots of "seeds", which exposed some quadratic behaviour
in adding and removing seeds. To fix this, we add a vbackptr array, which
points to the arc whose vleftptr entry points to us, and a vlastins array,
which shows where in an arc's vdownptr/vleftptr list we last inserted a
parent, which acts as a hint of a good place to start looking for where to
insert a new child.
This also ensures the children array elements stay in sorted order at all
times. We weren't resorting the children lists when reassigning tokens
in renumbervarc. Since the children lists are now always sorted, we don't
have to search through all elements to find the one with the highest token;
we can just use the last element.

First, update_arcrows was being overly aggressive in trimming
displayorder, resulting in calls to rowofcommit sometimes trimming off
commits that layoutrows had asked for in make_disporder and was relying
on having present. This adds a vrowmod($view) variable that lets
update_arcrows be more precise in trimming off the invalid bits of
displayorder (and it also simplifies the check in make_disporder).
This modifies modify_arc and its callers so that vrowmod($view) is
updated appropriately.
Secondly, we were sometimes calling idcol with $i==-1, which resulted
in a call to ordertoken with the null string. This fixes it by
forcing $i to 0 if it is less than zero.
This also fixes a possible infinite recursion with rowofcommit and
update_arcrows calling each other ad infinitum.

Instead of computing ordertok values and arc row numbers in
getcommitlines, this defers computing them until they are needed.
So getcommitlines no longer calls update_arcrows; instead it gets
called from rowofcommit and make_disporder. Things that modify arcs
now call modify_arc instead of setting vtokmod/varcmod directly,
and modify_arc does the undolayout that used to be in update_arcrows.
Also, idcol and make_idlist now use a new ordertoken function instead
of the ordertok variable. ordertoken uses ordertok as a cache, but
can itself compute the ordering tokens from scratch. This means that
the ordering tokens (and hence the layout of the graph) is once again
determined by the topological ordering we put on the graph, not on the
order in which we see the commits from git log, which improves the
appearance of the graph.

This very large patch implements code to organize the commits from
git log into "arcs" (sequences of commits where each pair of adjacent
commits are the only parent and child of each other), and orders the
arcs so as to get a topological ordering of the commits. This means
we can use git log without --topo-order and display the commits as we
get them, incrementally, which makes the cold-cache start up time much
faster, particularly on unpacked repos.
One beneficial effect of this is that the File->Update menu item now
just adds any new commits to the existing graph instead of rereading
the whole thing from scratch, which is much faster. (If you do want
to reread the whole graph from scratch you can use File->Reload.)
At an implementation level, this means that the displayorder and
parentlist lists are no longer fully valid at all times, and the
commitrow array has gone. New procedures commitinview and commitonrow
replace the commitrow array, and make_disporder ensures that
displayorder and parentlist are valid for a range of rows.
The overall time to load the kernel repository has gone up a bit, from
~9 seconds to ~11 seconds on my G5, but I think that is worth it given
that the time to get a window up with commits displayed in it has gone
from ~3 seconds to under 1 second.
