For exclude patterns read in from files, the filename is stored in the
exclude list, and the originating line number is stored in the
individual exclude (counting starting at 1).
For exclude patterns provided on the command line, a string describing
the source of the patterns is stored in the exclude list, and the
sequence number assigned to each exclude pattern is negative, with
counting starting at -1. So for example the 2nd pattern provided via
--exclude would be numbered -2. This allows any future consumers of
that data to easily distinguish between exclude patterns from files
vs. from the CLI.

Previously each exclude_list could potentially contain patterns
from multiple sources. For example dir->exclude_list[EXC_FILE]
would typically contain patterns from .git/info/exclude and
core.excludesfile, and dir->exclude_list[EXC_DIRS] could contain
patterns from multiple per-directory .gitignore files during
directory traversal (i.e. when dir->exclude_stack was more than
one item deep).
We split these composite exclude_lists up into three groups of
exclude_lists (EXC_CMDL / EXC_DIRS / EXC_FILE as before), so that each
exclude_list now contains patterns from a single source. This will
allow us to cleanly track the origin of each pattern simply by adding
a src field to struct exclude_list, rather than to struct exclude,
which would make memory management of the source string tricky in the
EXC_DIRS case where its contents are dynamically generated.
Similarly, by moving the filebuf member from struct exclude_stack to
struct exclude_list, it allows us to track and subsequently free
memory buffers allocated during the parsing of all exclude files,
rather than only tracking buffers allocated for files in the EXC_DIRS
group.

Since b57fb80a7d (init, clone: support --separate-git-dir for .git file)
git clone supports the --separate-git-dir option to create the git dir
outside the work tree. But when that option is used, the git dir won't be
deleted in case the clone fails like it would be without this option. This
makes clone lose its atomicity as in case of a failure a partly set up git
dir is left behind. A real world example where this leads to problems is
when "git submodule update" fails to clone a submodule and later calls to
"git submodule update" stumble over the partially set up git dir and try
to revive the submodule from there, which then fails with a not very user
friendly error message.
Fix that by updating the junk_git_dir variable (used to remember if and
what git dir should be removed in case of failure) to the new value given
with the --seperate-git-dir option. Also add a test for this to t5600 (and
while at it fix the former last test to not cd into a directory to test
for its existence but use "test -d" instead).

When it added a call to run the prepare-commit-msg hook, however, it

The previous commit documented two known breakages revolving around
a case where one side flips a tree into a blob (or vice versa),
where the original code simply gets confused and feeds a mixture of
trees and blobs into either the recursive merge-tree (and recursing
into the blob will fail) or three-way merge (and merging tree contents
together with blobs will fail).
Fix it by feeding trees (and only trees) into the recursive
merge-tree machinery and blobs (and only blobs) into the three-way
content level merge machinery separately; when this happens, the
entire merge has to be marked as conflicting at the structure level.

The --reroll-count=$N option, when given a positive integer:
- Adds " v$N" to the subject prefix specified. As the default
subject prefix string is "PATCH", --reroll-count=2 makes it
"PATCH v2".
- Prefixes "v$N-" to the names used for output files. The cover
letter, whose name is usually 0000-cover-letter.patch, becomes
v2-0000-cover-letter.patch when given --reroll-count=2.
This allows users to use the same --output-directory for multiple
iterations of the same series, without letting the output for a
newer round overwrite output files from the earlier rounds. The
user can incorporate materials from earlier rounds to update the
newly minted iteration, and use "send-email v2-*.patch" to send out
the patches belonging to the second iteration easily.

When an object has already been exported (and thus is in the marks) it's
flagged as SHOWN, so it will not be exported again, even if in a later
time it's exported through a different ref.
We don't need the object to be exported again, but we want the ref
updated, which doesn't happen.
Since we can't know if a ref was exported or not, let's just assume that
if the commit was marked (flags & SHOWN), the user still wants the ref
updated.
IOW: If it's specified in the command line, it will get updated,
regardless of whether or not the object was marked.
So:
% git branch test master
% git fast-export $mark_flags master
% git fast-export $mark_flags test
Would export 'test' properly.
Additionally, this fixes issues with remote helpers; now they can push
refs whose objects have already been exported, and a few other issues as
well. Update the tests accordingly.

They have been marked as UNINTERESTING for a reason, lets respect
that. Currently the first ref is handled properly, but not the
rest. Assuming that all the refs point at the same commit in the
following example:
% git fast-export master ^uninteresting ^foo ^bar
reset refs/heads/bar
from :0
reset refs/heads/foo
from :0
reset refs/heads/uninteresting
from :0
% git fast-export ^uninteresting ^foo ^bar master
reset refs/heads/master
from :0
reset refs/heads/bar
from :0
reset refs/heads/foo
from :0
Clearly this is wrong; the negative refs should be ignored.
After this patch:
% git fast-export ^uninteresting ^foo ^bar master
# nothing
% git fast-export master ^uninteresting ^foo ^bar
# nothing
And even more, it would only happen if the ref is pointing to exactly
the same commit, but not otherwise:
% git fast-export ^next next
reset refs/heads/next
from :0
% git fast-export ^next next^{commit}
# nothing
% git fast-export ^next next~0
# nothing
% git fast-export ^next next~1
# nothing
% git fast-export ^next next~2
# nothing
The reason this happens is that before traversing the commits,
fast-export checks if any of the refs point to the same object, and any
duplicated ref gets added to a list in order to issue 'reset' commands
after the traversing. Unfortunately, it's not even checking if the
commit is flagged as UNINTERESTING. The fix of course, is to check it.
However, in order to do it properly we need to get the UNINTERESTING
flag from the command line, not from the commit object, because
"^foo bar" will mark the commit 'bar' uninteresting if foo and bar
points at the same commit. rev_cmdline_info, which was introduced
exactly to handle this situation, contains all the information we
need for get_tags_and_duplicates(), plus the ref flag. This way the
rest of the positive refs will remain untouched; it's only the
negative ones that change in behavior.

Doing a "git rm submod/" on a submodule results in an error:
fatal: pathspec 'submod/' did not match any files
This is really inconvenient as e.g. using TAB completion in a shell on a
submodule automatically adds the trailing '/' when it completes the path
of the submodule directory. The user has then to remove the '/' herself to
make a "git rm" succeed. Doing a "git rm -r somedir/" is working fine, so
there is no reason why that shouldn't work for submodules too.
Teach git rm to not error out when a '/' is appended to the path of a
submodule. Achieve this by chopping off trailing slashes from the path
names given if they represent directories. Add tests to make sure that
logic only applies to directories and not to files.

We keep track of whether the user ident was given to us
explicitly, or if we guessed at it from system parameters
like username and hostname. However, we kept only a single
variable. This covers the common cases (because the author
and committer will usually come from the same explicit
source), but can miss two cases:
1. GIT_COMMITTER_* is set explicitly, but we fallback for
GIT_AUTHOR. We claim the ident is explicit, even though
the author is not.
2. GIT_AUTHOR_* is set and we ask for author ident, but
not committer ident. We will claim the ident is
implicit, even though it is explicit.
This patch uses two variables instead of one, updates both
when we set the "fallback" values, and updates them
individually when we read from the environment.
Rather than keep user_ident_sufficiently_given as a
compatibility wrapper, we update the only two callers to
check the committer_ident, which matches their intent and
