fast-import: grow tree storage more aggressively
When building up a tree for a commit, fast-import

re-allocating and memcpy()ing the memory O(n) times.
To compound this problem, releasing the previous tree

Teach receive-pack to run pre-receive/post-receive hooks
Bill Lear pointed out that it is easy to send out notifications of
changes with the update hook, but successful execution of the update
hook does not necessarily mean that the ref was actually updated.
Lock contention on the ref or being unable to append to the reflog
may prevent the ref from being changed. Sending out notifications
prior to the ref actually changing is very misleading.
To help this situation I am introducing two new hooks to the
receive-pack flow: pre-receive and post-receive. These new hooks
are invoked only once per receive-pack execution and are passed
three arguments per ref (refname, old-sha1, new-sha1).
The new post-receive hook is ideal for sending out notifications,
as it has the complete list of all refnames that were successfully
updated as well as the old and new SHA-1 values. This allows more
interesting notifications to be sent. Multiple ref updates could
be easily summarized into one email, for example.
The new pre-receive hook is ideal for logging update attempts, as it
is run only once for the entire receive-pack operation. It can also
be used to verify multiple updates happen at once, e.g. an update
to the `maint` head must also be accompained by a new annotated tag.
Lots of documentation improvements for receive-pack are included

if the ref was not updated because the repository has the config

when returning back a failure from update()
We now return an ng line for a non-fastforward update, which in

Hence the modified test.
This refactoring changes update to return a const char* describing
the error, which execute_commands always loads into error_string.

Use off_t when we really mean a file offset.
Not all platforms have declared 'unsigned long' to be a 64 bit value,
but we want to support a 64 bit packfile (or close enough anyway)
in the near future as some projects are getting large enough that
their packed size exceeds 4 GiB.
By using off_t, the POSIX type that is declared to mean an offset
within a file, we support whatever maximum file size the underlying
operating system will handle. For most modern systems this is up
around 2^60 or higher.

Use uint32_t for pack-objects counters.
As we technically try to support up to a maximum of 2**32-1 objects
in a single packfile we should act like it and use unsigned 32 bit
integers for all of our object counts and progress output.
This change does not modify everything in pack-objects that probably
needs to change to fully support the maximum of 2**32-1 objects.
I'm intentionally breaking the improvements into slightly smaller
commits to make them easier to follow.
No logic change should be occuring here, with the exception that
some comparsions will now work properly when the number of objects
exceeds 2**31-1.

General const correctness fixes
We shouldn't attempt to assign constant strings into char*, as the
string is not writable at runtime. Likewise we should always be
treating unsigned values as unsigned values, not as signed values.
Most of these are very straightforward. The only exception is the
(unnecessary) xstrdup/free in builtin-branch.c for the detached
head case. Since this is a user-level interactive type program
and that particular code path is executed no more than once, I feel
that the extra xstrdup call is well worth the easy elimination of
this warning.

Fix mmap leak caused by reading bad indexes.
If an index is corrupt, or is simply too new for us to understand,

Display the null SHA-1 as the base for an OBJ_OFS_DELTA.
Because we are currently cheating and never supplying the delta base

git-archimport: allow remapping branch names
This patch adds support to archimport for remapping the branch
names to match those used in git more closely. This is useful
for projects that migrate to git (as opposed to users that want
to use git on Arch-based projects). For example, one can choose
an Arch branch name and call it "master".
The new command-line syntax works even if there is a colon in
a branch name, since only the part after the last colon is taken
to be the git name (git does not allow colons in branch names).
The new feature is implemented so that archives rotated every
year can also be remapped into a single git archive.

The rules for escaping attribute values (which are string contents) are
different. For example you have to take care about escaping embedded '"'
and "'" characters; CGI::a() does that for us automatically.
CGI::a() does not HTML escape tag_contents; we would need to write
<a href="URL">some <b>bold</b> text</a>
for example. So we use esc_html (or esc_path) to escape tag_contents
as needed.

The test was recently broken to expect sed to leave the
incomplete line at the end without newline.
POSIX says that output of the pattern space is to be followed by
a newline, while GNU adds the newline back only when it was
stripped when input. GNU behaviour is arguably more intuitive
and nicer, but we should not depend on it.

revision walker: Fix --boundary when limited
This cleans up the boundary processing in the commit walker. It
- rips out the boundary logic from the commit walker. Placing
"negative" commits in the revs->commits list was Ok if all we
cared about "boundary" was the UNINTERESTING limiting case,
but conceptually it was wrong.
- makes get_revision_1() function to walk the commits and return
the results as if there is no funny postprocessing flags such
as --reverse, --skip nor --max-count.
- makes get_revision() function the postprocessing phase:
If reverse is given, wait for get_revision_1() to give
everything that it would normally give, and then reverse it
before consuming.
If skip is given, skip that many before going further.
If max is given, stop when we gave out that many.
Now that we are about to return one positive commit, mark
the parents of that commit to be potential boundaries
before returning, iff we are doing the boundary processing.
Return the commit.
- After get_revision() finishes giving out all the positive
commits, if we are doing the boundary processing, we look at
the parents that we marked as potential boundaries earlier,
see if they are really boundaries, and give them out.
It loses more code than it adds, even when the new gc_boundary()
function, which is purely for early optimization, is counted.
Note that this patch is purely for eyeballing and discussion
only. It breaks git-bundle's verify logic because the logic
does not use BOUNDARY_SHOW flag for its internal computation
anymore. After we correct it not to attempt to affect the
boundary processing by setting the BOUNDARY_SHOW flag, we can
remove BOUNDARY_SHOW from revision.h and use that bit assignment
for the new CHILD_SHOWN flag.

Make 'make' quieter while building git
I find it difficult to see compiler warnings amongst the massive
spewing produced by GNU make as it works through our productions.
This is especially true if CFLAGS winds up being rather long, due
to a large number of -W options being enabled and due to a number
of -D options being configured/required by my platform.
By defining QUIET_MAKE (e.g. make QUIET_MAKE=YesPlease) during
compilation users will get a less verbose output, such as:
...
CC builtin-grep.c
builtin-grep.c:187: warning: 'external_grep' defined but not used
CC builtin-init-db.c
CC builtin-log.c
CC builtin-ls-files.c
