When overriding the identifier "stat" so that "struct stat" will be
substituted with "struct _stati64" everywhere, I tried to fix the calls
to the _function_ stat(), too, but I forgot to change the earlier
attempt "stat64" to "_stati64" there.
So, the stat() calls were overridden by calls to _stati64() instead.
Unfortunately, there is a function _stati64() so that I missed that
calls to stat() were not actually overridden by calls to mingw_lstat(),
but t4200-rerere.sh showed the error.

This reverts commit 6d3e71d428.
Apparently, GCC >= 4 does not like %I64u as modifier to show unsigned
long longs. However, using %llu -- even if the compiler warning goes
away -- fails spectacularly: The C runtime insists that %llu takes
32-bit numbers.
So for now, we _have_ to live with compiler warnings galore.

The type 'off_t' should be used everywhere so that the bit-depth of that
type can be adjusted in the standard C library, and you just need to
recompile your program to benefit from the extended precision.
Only that it was not done that way in the MS runtime library.
This patch reroutes off_t to off64_t and provides the other necessary
changes so that finally, clones larger than 2 gigabyte work on Windows
(provided you are on a file system that allows files larger than 2gb).

When memmem() was imported from glibc 2.2 into compat/, an optimization
was dropped in the process, in order to make the code smaller and simpler.
It was OK because memmem() wasn't used in performance-critical code. Now
the situation has changed and we can benefit from this optimization.
The trick is to avoid calling memcmp() if the first character of the needle
already doesn't match. Checking one character directly is much cheaper
than the function call overhead. We keep the first character of the needle
in the variable named point and the rest in the one named tail.
The following commands were run in a Linux kernel repository and timed, the
best of five results is shown:
$ STRING='Ensure that the real time constraints are schedulable.'
$ git log -S"$STRING" HEAD -- kernel/sched.c >/dev/null

Apparently, CREATE_NO_WINDOW makes the OS tell the process
that it has a console, but without actually creating the
window. As a result, when git is started from GUI, ssh
tries to ask its questions on the invisible console.
This patch uses DETACHED_PROCESS instead, which clearly
means that the process should be left without a console.
The downside is that if the process manually calls
AllocConsole, the window will appear. A similar thing
might occur if it calls another console executable.

The original patch that lead to an earlier commit adbc0b6 (cygwin: Use
native Win32 API for stat, 2008-09-30) did not call git_default_config()
and it was a good thing. The lazy config reading when lstat/stat is
called for the first time to find out if core.filemode is set can happen
anytime in the calling program. If it happens after the calling program
parsed the configuration file to prime its default parameter settings and
processed its command line parameters to tweak them, this will overwrite
the values set by the program with the values read from the config file.
This essentially reverts the code to the version as submitted by Mark,
with a bit more comments to clarify why we do not fall back on the default
configuration parser from git_cygwin_config().

Cygwin's POSIX emulation allows use of core.filemode true, unlike native
Window's implementation of stat / lstat, and Cygwin/git users who have
configured core.filemode true in various repositories will be very
unpleasantly surprised to find that git is no longer honoring that option.
So, this patch forces use of Cygwin's stat functions if core.filemode is
set true, regardless of any other considerations.

lstat/stat functions in Cygwin are very slow, because they try to emulate
some *nix things that Git does not actually need. This patch adds Win32
specific implementation of these functions for Cygwin.
This implementation handles most situation directly but in some rare cases
it falls back on the implementation provided for Cygwin. This is necessary
for two reasons:
- Cygwin has its own file hierarchy, so absolute paths used in Cygwin is
not suitable to be used Win32 API. cygwin_conv_to_win32_path can not be
used because it automatically dereference Cygwin symbol links, also it
causes extra syscall. Fortunately Git rarely use absolute paths, so we
always use Cygwin implementation for absolute paths.
- Support of symbol links. Cygwin stores symbol links as ordinary using
one of two possible formats. Therefore, the fast implementation falls
back to Cygwin functions if it detects potential use of symbol links.
The speed of this implementation should be the same as mingw_lstat for
common cases, but it is considerable slower when the specified file name
does not exist.
Despite all efforts to make the fast implementation as robust as possible,
it may not work well for some very rare situations. I am aware only one
situation: use Cygwin mount to bind unrelated paths inside repository
together. Therefore, the core.ignoreCygwinFSTricks configuration option is
provided, which controls whether native or Cygwin version of stat is used.

The standard libc regex library on OSX does not support alternation
in POSIX Basic Regular Expression mode. This breaks the diff.funcname
functionality on OSX.
To fix this, we use the GNU regex library which is already present in
the compat/ diretory for the MinGW port. However, simply adding compat/
to the COMPAT_CFLAGS variable causes a conflict between the system
fnmatch.h and the one present in compat/. To remedy this, move the
regex and fnmatch functionality to their own subdirectories in compat/
so they can be included seperately.

compat/snprintf.c: handle snprintf's that always return the # chars transmitted
git-svn: fix dcommit to urls with embedded usernames
revision.h: make show_early_output an extern which is defined in revision.c
Some platforms provide a horribly broken snprintf. More broken than the
platforms that return -1 when there is too little space in the target buffer
for the formatted string. Some platforms provide an snprintf which _always_
returns the number of characters transmitted to the buffer, regardless of
whether there was enough space or not.
IRIX 6.5 is such a platform. IRIX does have a working snprintf(), but it
is only provided when _NO_XOPEN5 evaluates to zero, and this only happens
if _XOPEN_SOURCE is defined, but definition of _XOPEN_SOURCE prevents
inclusion of many other common functions and defines. So it must be avoided.
Work around these horribly broken snprintf implementations by detecting an
snprintf call which results in the number of transmitted characters exactly
equal to the length of our buffer and retrying with a larger buffer just to
be safe.

Some platforms do not have st_blocks member in "struct stat"; mingw

though it could overcount when a file has holes).

files occupy on-disk, so give a helper function in git-compat-util.h to
compute this value.

Since the exec-path on Windows is derived from the program invocation path,
we must ensure that argv[0] always has a path. Unfortunately, if a program
is invoked from CMD, argv[0] has no path. But on the other hand, the
C runtime offers a global variable, _pgmptr, that always has the full path
to the program. We hook into main() with a preprocessor macro, where we
replace argv[0].

The system's default browser for displaying HTML help pages is now used
directly on Windows, instead of launching git-web--browser, which
requires a Unix shell. Avoiding MSYS' bash when possible is good
because it avoids potential path translation issues. In this case it is
not too hard to avoid launching a shell, so let's avoid it.
The Windows-specific code is implemented in compat/mingw.c to avoid
platform-specific code in the main code base. On Windows, open_html is
provided as a define. If open_html is not defined, git-web--browse is
used. This approach avoids platform-specific ifdefs by using
per-function ifdefs. The "ifndef open_html" together with the
introductory comment should sufficiently warn developers, so that they
hopefully will not break this mechanism.
