Many of the date functions write into fixed-size buffers.
This is a minor pain, as we have to take special
precautions, and frequently end up copying the result into a
strbuf or heap-allocated buffer anyway (for which we
sometimes use strcpy!).
Let's instead teach parse_date, datestamp, etc to write to a
strbuf. The obvious downside is that we might need to
perform a heap allocation where we otherwise would not need
to. However, it turns out that the only two new allocations
required are:
1. In test-date.c, where we don't care about efficiency.
2. In determine_author_info, which is not performance
critical (and where the use of a strbuf will help later
refactoring).

Reading into a time_t isn't portable, since we don't know
the exact type. Instead, use an unsigned long, which is what
show_date wants, anyway.

Previously, test-date simply ignored the parsed timezone and
told show_date() to use UTC. Instead, let's print out what
we actually parsed.
While we're at it, let's make it easy for tests to work in a specific
timezone.

The test-date program goes back to the early days of git,
where it was presumably used to do manual sanity checks on
changes to the date code. However, it is not actually used
by the test suite to do any sort of automatic of systematic
tests.
This patch refactors the interface to the program to try to
make it more suitable for use by the test suite. There
should be no fallouts to changing the interface since it is
not actually installed and is not internally called by any
other programs.
The changes are:
- add a "mode" parameter so the caller can specify which
operation to test
- add a mode to test relative date output from show_date
- allow faking a fixed time via the TEST_DATE_NOW
environment variable, which allows consistent automated
testing
- drop the use of ctime for showing dates in favor of our
internal iso8601 printing routines. The ctime output is
somewhat redundant (because of the day-of-week) which
makes writing test cases more annoying.

This is a mechanical clean-up of the way *.c files include
system header files.
(1) sources under compat/, platform sha-1 implementations, and
xdelta code are exempt from the following rules;
(2) the first #include must be "git-compat-util.h" or one of
our own header file that includes it first (e.g. config.h,
builtin.h, pkt-line.h);
(3) system headers that are included in "git-compat-util.h"
need not be included in individual C source files.
(4) "git-compat-util.h" does not have to include subsystem
specific header files (e.g. expat.h).

And be a bitmore careful about matching: if we don't recognize a word
or a number, we skip the whole thing, rather than trying the next character
in that word/number.
Finally: since ctime() adds the final '\n', don't add another one in test-date.
