In this code, we try to convert both "foo.idx" and "foo"
into "foo.pack". By stripping the suffix, we can avoid a
confusing use of strbuf_splice, and make it clear that both
cases are adding ".pack" to the end.

You can almost get away with just calling "strip_suffix_mem"
on a strbuf's buf and len fields. But we also need to move
the NUL-terminator to satisfy strbuf's invariants. Let's
provide a convenience wrapper that handles this.

We also switch to using strbufs, which lets us avoid the
potentially dangerous combination of a manual malloc
followed by a strcpy.

When stripping a suffix like:
if (ends_with(str, "foo"))
buf = xmemdupz(str, strlen(str) - 3);
we can instead use strip_suffix to avoid the constant 3,
which must match the literal "foo" (we sometimes use
strlen("foo") instead, but that means we are repeating
ourselves). The example above becomes:
if (strip_suffix(str, "foo", &len))
buf = xmemdupz(str, len);
This also saves a strlen(), since we calculate the string
length when detecting the suffix.
Note that in some cases we also switch from xstrndup to
xmemdupz, which saves a further strlen call.

These two are almost the same function, with the exception
that has_extension only matches if there is content before
the suffix. So ends_with(".exe", ".exe") is true, but
has_extension would not be.
This distinction does not matter to any of the callers,
though, and we can just replace uses of has_extension with
ends_with. We prefer the "ends_with" name because it is more
generic, and there is nothing about the function that
requires it to be used for file extensions.

The ends_with function is essentially a simplified version
of strip_suffix, in which we throw away the stripped length.
Implementing it as an inline on top of strip_suffix has two
advantages:
1. We save a bit of duplicated code.
2. The suffix is typically a string literal, and we call
strlen on it. By making the function inline, many
compilers can replace the strlen call with a constant.

Many callers of ends_with want to not only find out whether
a string has a suffix, but want to also strip it off. Doing
that separately has two minor problems:
1. We often run over the string twice (once to find
the suffix, and then once more to find its length to
subtract the suffix length).
2. We have to specify the suffix length again, which means
either a magic number, or repeating ourselves with
strlen("suffix").
Just as we have skip_prefix to avoid these cases with
starts_with, we can add a strip_suffix to avoid them with
ends_with.
Note that we add two forms of strip_suffix here: one that
takes a string, with the resulting length as an
out-parameter; and one that takes a pointer/length pair, and
reuses the length as an out-parameter. The latter is more
efficient when the caller already has the length (e.g., when
using strbufs), but it can be easy to confuse the two, as
they take the same number and types of parameters.
For that reason, the "mem" form puts its length parameter
next to the buffer (since they are a pair), and the string
form puts it at the end (since it is an out-parameter). The
compiler can notice when you get the order wrong, which
should help prevent writing one when you meant the other.

Instead of using strbuf to create a message string in case a path is
too long for our fixed-size buffer, replace that buffer with a strbuf
and thus get rid of the limitation.

"git status" (and "git commit") behaved as if changes in a modified

This mistyped command line simply ignores "master" and ends up
showing two commits from the current HEAD:

These two commands are supposed to be equivalent:
$ git log --exclude=refs/notes/\* --all --no-merges --since=2.days |
git shortlog
$ git shortlog --exclude=refs/notes/\* --all --no-merges --since=2.days
However, the latter does not understand the ref-exclusion command
line option, even though other options understood by "log", such as
"--all" and "--no-merges", are understood.
This was because e7b432c5 (revision: introduce --exclude=<glob> to
tame wildcards, 2013-08-30) did not wire the new option fully to the
machinery. A new option understood by handle_revision_pseudo_opt()
must be told to handle_revision_opt() as well.

Running "git update-index --cacheinfo" without any further
arguments results in a segfault rather than an error
message. Commit ec160ae (update-index: teach --cacheinfo a
new syntax "mode,sha1,path", 2014-03-23) added code to
examine the format of the argument, but forgot to handle the
NULL case.
Returning an error from the parser is enough, since we then
treat it as an old-style "--cacheinfo <mode> <sha1> <path>",
and complain that we have less than 3 arguments to read.

Whenever the hash table becomes too small then its size is increased,
the original part (and the added space) is zerod out using memset(),
and the table is rebuilt from scratch.
Simplify this proceess by returning the old memory using free() and
allocating the new buffer using xcalloc(), which already clears the
buffer for us. That way we avoid copying the old hash table contents
needlessly inside xrealloc().
While at it, use the first array member with sizeof instead of a
specific type. The old code used uint32_t and int, while index is
actually an array of int32_t. Their sizes are the same basically
everywhere, so it's not actually a problem, but the new code is
cleaner and doesn't have to be touched should the type be changed.

The array header is defined as:
static const char *header[MAX_HDR_PARSED] = {
"From","Subject","Date",
};
When looking for the index of a specfic string in that array, simply
use strcmp() instead of memcmp(). This avoids running over the end of
the string (e.g. with memcmp("Subject", "From", 7)) and gets rid of
magic string length constants.

Diagnostic messages received on the sideband #2 from the server side
are sent to the standard error with ANSI terminal control sequence
"\033[K" that erases to the end of line appended at the end of each
line.
However, some programs (e.g. GitExtensions for Windows) read and
interpret and/or show the message without understanding the terminal
control sequences, resulting them to be shown to their end users.
To help these programs, squelch the control sequence when the
standard error stream is not being sent to a tty.
NOTE: I considered to cover the case that a pager has already been
started. But decided that is probably not worth worrying about here,
though, as we shouldn't be using a pager for commands that do network
communications (and if we do, omitting the magic line-clearing signal
is probably a sane thing to do).

As 0232852b, but for the push tests instead: this avoids a start_httpd
in the middle of the file, which fails under GIT_TEST_HTTPD=false.
Note that we have to munge the test in a few ways while
moving it:
1. We drop the `test -z "$GIT_TEST_HTTPD"` check; this is
too simplistic since 83d842d, and we should let
lib-httpd.sh handle it.
2. We have to port over some of the old setup from t5538.
3. In the final test, we no longer expect the extra commit
"1" built on top of "4". This was a side effect from an
earlier test in t5538 which was not ported over.

These were originally removed by 0232852 (t5537: move
http tests out to t5539, 2014-02-13). However, they were
accidentally re-added in 1ddb4d7 (Merge branch
'nd/upload-pack-shallow', 2014-03-21).
This looks like an error in manual conflict resolution.
Here's what happened:
1. v1.9.0 shipped with the http tests in t5537.
2. We realized that this caused problems, and built
0232852 on top to move the tests to their own file.
This fix made it into v1.9.1.
3. We later had another fix in nd/upload-pack-shallow that
also touched t5537. It was built directly on v1.9.0.
When we merged nd/upload-pack-shallow to master, we got a
conflict; it was built on a version with the http tests, but
we had since removed them. The correct resolution was to
drop the http tests and keep the new ones, but instead we
kept everything.
