Many call sites use strbuf_init(&foo, 0) to initialize local
strbuf variable "foo" which has not been accessed since its
declaration. These can be replaced with a static initialization
using the STRBUF_INIT macro which is just as readable, saves a
function call, and takes up fewer lines.

When you misuse a git command, you are shown the usage string.
But this is currently shown in the dashed form. So if you just
copy what you see, it will not work, when the dashed form
is no longer supported.
This patch makes git commands show the dash-less version.
For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh
generates a dash-less usage string now.

Move all functionality (except config and option parsing) from
cmd_fmt_merge_msg() to fmt_merge_msg(), so that other builtins can use
it without a child process.
All functions have been changed to use strbufs, and now only
cmd_fmt_merge_msg() reads directly from a file / writes anything to
stdout.

git_config() only had a function parameter, but no callback data
parameter. This assumes that all callback functions only modify
global variables.
With this patch, every callback gets a void * parameter, and it is hoped
that this will help the libification effort.

These are new synonyms to the '--(no-)summary' option and the
'merge.summary' config variable, but are consistent with the soon to be
added 'merge --(no-)log' options. The 'merge.summary' config variable and
'--(no-)summary' options are still accepted, but are advertised to be
removed in the future.
'merge.log' takes precedence over 'merge.summary' if they are both set
inconsistently.
Update documentation and tests accordingly.

We cannot tell a node that has been checked and found not to be
interesting (which does not have the TREECHANGE flag) from a
node that hasn't been checked if it is interesting or not,
without relying on something else, such as object->parsed.
But an object can get the "parsed" flag for other reasons.
Which means that "TREECHANGE" has the wrong polarity.
This changes the way how the path pruning logic marks an
uninteresting commits. From now on, we consider a commit
interesting by default, and explicitly mark the ones we decided
to prune. The flag is renamed to "TREESAME".
Then, this fixes the logic to show the early output with
incomplete pruning. It basically says "a commit that has
TREESAME set is kind-of-UNINTERESTING", but obviously in a
different way than an outright UNINTERESTING commit. Until we
parse and examine enough parents to determine if a commit
becomes surely "kind-of-UNINTERESTING", we avoid rewriting
the ancestry so that later rounds can fix things up.

This mechanically converts strncmp() to use prefixcmp(), but only when
the parameters match specific patterns, so that they can be verified
easily. Leftover from this will be fixed in a separate step, including
idiotic conversions like
if (!strncmp("foo", arg, 3))
=>
if (!(-prefixcmp(arg, "foo")))
This was done by using this script in px.perl
#!/usr/bin/perl -i.bak -p
if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) {
s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|;
}
if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) {
s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|;
}
and running:
$ git grep -l strncmp -- '*.c' | xargs perl px.perl

Ok, this is a _really_ stupid case, and I don't think it matters, but hey,
we should never SIGSEGV.
Steps to reproduce:
mkdir duh
cd duh
git init-db
git-fmt-merge-msg < /dev/null
will cause a SIGSEGV in cmd_fmt_merge_msg(), because we're doing a
strncmp() with a NULL current_branch.
And yeah, it's an insane schenario, and no, it doesn't really matter. The
only reason I noticed was that a broken version of my "git pull" into an
empty directory would cause this.
This silly patch just replaces the SIGSEGV with a controlled exit with an
error message.

This adds a "int *flag" parameter to resolve_ref() and makes
for_each_ref() family to call callback function with an extra
"int flag" parameter. They are used to give two bits of
information (REF_ISSYMREF and REF_ISPACKED) about the ref.

The old code used to totally mix up the notion of a ref-name and the path
that that ref was associated with. That was not only horribly ugly (a
number of users got the path, and then wanted to try to turn it back into
a ref-name again), but it fundamnetally doesn't work at all once we do any
setup where a ref doesn't have a 1:1 relationship with a particular
pathname.
This fixes things up so that we use the ref-name throughout, and only
turn it into a pathname once we actually look it up in the filesystem.
That makes a lot of things much clearer and more straightforward.

Like xmalloc and xrealloc xstrdup dies with a useful message if
the native strdup() implementation returns NULL rather than a
valid pointer.
I just tried to use xstrdup in new code and found it to be missing.
However I expected it to be present as xmalloc and xrealloc are
already commonly used throughout the code.

Any git command that expects to work in a subdirectory of a project, and
that reads the git config files (which is just about all of them) needs to
make sure that it does the "setup_git_directory()" call before it tries to
read the config file.
This means, among other things, that we need to move the call out of
"init_revisions()", and into the caller.
This does the mostly trivial conversion to do that.

This updates the type-enumeration constants introduced to reduce
the memory footprint of "struct object" to match the type bits
already used in the packfile format, by removing the former
(i.e. TYPE_* constant macros) and using the latter (i.e. enum
object_type) throughout the code for consistency.
Eventually we can stop passing around the "type strings"
entirely, and this will help - no confusion about two different
integer enumeration.
