GetCurrentConsoleFontEx in an atexit routine doesn't work because git
closes stdout before exit (which also closes the console handle). Check
the console font when we first encounter a non-ascii character and only
schedule the warning message to be printed at exit (warnings go to stderr,
which is not closed by git).

MingwRT listens to _CRT_glob to decide if __getmainargs should
perform globbing, with the default being that it should.
Unfortunately, __getmainargs globbing is sub-par; for instance
patterns like "*.c" will only match c-sources in the current
directory.
Disable __getmainargs' command line wildcard expansion, so these
patterns will be left untouched, and handled by Git's superior
built-in globbing instead.
MSVC defaults to no globbing, so we don't need to do anything
in that case.
This fixes t5505 and t7810.

Improve the dirent implementation by removing the relics that were once
necessary to plug into the now unused MinGW runtime, in preparation for
Unicode file name support.
Move FindFirstFile to opendir, and FindClose to closedir, with the
following implications:
- DIR.dd_name is no longer needed
- chdir(one); opendir(relative); chdir(two); readdir() works as expected
(i.e. lists one/relative instead of two/relative)
- DIR.dd_handle is a valid handle for the entire lifetime of the DIR struct
- thus, all checks for dd_handle == INVALID_HANDLE_VALUE and dd_handle == 0
have been removed
- the special case that the directory has been fully read (which was
previously explicitly tracked with dd_handle == INVALID_HANDLE_VALUE &&
dd_stat != 0) is now handled implicitly by the FindNextFile error
handling code (if a client continues to call readdir after receiving
NULL, FindNextFile will continue to fail with ERROR_NO_MORE_FILES, to
the same effect)
- extracting dirent data from WIN32_FIND_DATA is needed in two places, so
moved to its own method
- GetFileAttributes is no longer needed. The same information can be
obtained from the FindFirstFile error code, which is ERROR_DIRECTORY if
the name is NOT a directory (-> ENOTDIR), otherwise we can use
err_win_to_posix (e.g. ERROR_PATH_NOT_FOUND -> ENOENT). The
ERROR_DIRECTORY case could be fixed in err_win_to_posix, but this
probably breaks other functionality.
Removes the ERROR_NO_MORE_FILES check after FindFirstFile (this was
fortunately a NOOP (searching for '*' always finds '.' and '..'),
otherwise the subsequent code would have copied data from an uninitialized
buffer).
Changes malloc to git support function xmalloc, so opendir will die() if
out of memory, rather than failing with ENOMEM and letting git work on
incomplete directory listings (error handling in dir.c is quite sparse).

i.e. && or || operators that are followed by anything but a SP,
or that follow something other than a SP or a HT, so that these

We usually refrain from making this kind of a tree-wide change in

In msvc.h, there's a couple of stat related functions defined diffently
from mingw.h. When we remove these definitions, the only problem we get is
"warning C4005: '_stati64' : macro redefinition" for this line in mingw.h:
#define _stati64(x,y) mingw_stat(x,y)
The reason is that as of MSVCR80.dll (distributed with MSVC 2005), the
original _stati64 family of functions was renamed to _stat32i64, and the
former function names became macros (pointing to the appropriate function
based on the definition of _USE_32BIT_TIME_T).
Defining _stati64 works on MinGW because MinGW by default compiles against
the MSVCRT.DLL that is part of Windows (i.e. _stati64 is a function rather
than a macro).
Note: MinGW *can* compile for newer MSVC runtime versions, and MSVC
apparently can also compile for the Windows MSVCRT.DLL via the DDK (see
http://www.syndicateofideas.com/posts/fighting-the-msvcrt-dll-hell ).
Remove the stat definitions from msvc.h, as they are not compiler related.
In mingw.h, determine the runtime version in use from the definitions of
_stati64 and _USE_32BIT_TIME_T, and define stat() accordingly.
This also fixes that stat() in MSVC builds still resolves to mingw_lstat()
instead of mingw_stat().

Commit adbc0b6b ("cygwin: Use native Win32 API for stat", 30-09-2008)
added a Win32 specific implementation of the stat functions. In order
to handle absolute paths, cygwin mount points and symbolic links, this
implementation may fall back on the standard cygwin l/stat() functions.
Also, the choice of cygwin or Win32 functions is made lazily (by the
first call(s) to l/stat) based on the state of some config variables.
Unfortunately, this "schizophrenic stat" implementation has been the
source of many problems ever since. For example, see commits 7faee6b8,
79748439, 452993c2, 085479e7, b8a97333, 924aaf3e, 05bab3ea and 0117c2f0.

Commit 380a4d92 ("Update cygwin.c for new mingw-64 win32 api headers",
11-11-2012) solved an header include order problem on cygwin 1.7 when
using the new mingw-64 WIN32 API headers. The solution involved using
a new build variable (V15_MINGW_HEADERS) to conditionally compile the
cygwin.c source file to use an include order appropriate for the old
and new header files. (The build variable was later renamed in commit
9fca6cff to CYGWIN_V15_WIN32API).
The include order used for cygwin 1.7 includes the "win32.h" header
before "../git-compat-util.h". This order was problematic on cygwin
1.5, since it lead to the WIN32 symbol being defined along with the
inclusion of some WIN32 API headers (e.g. <winsock2.h>) which cause
compilation errors.
The header include order problem on cygwin 1.5 has since been fixed
(see commit "mingw: rename WIN32 cpp macro to GIT_WINDOWS_NATIVE"),
so we can now remove the conditional compilation along with the
associated CYGWIN_V15_WIN32API build variable.

Throughout git, it is assumed that the WIN32 preprocessor symbol is
defined on native Windows setups (mingw and msvc) and not on Cygwin.
On Cygwin, most of the time git can pretend this is just another Unix
machine, and Windows-specific magic is generally counterproductive.
Unfortunately Cygwin *does* define the WIN32 symbol in some headers.
Best to rely on a new git-specific symbol GIT_WINDOWS_NATIVE instead,
defined as follows:
#if defined(WIN32) && !defined(__CYGWIN__)
# define GIT_WINDOWS_NATIVE
#endif
After this change, it should be possible to drop the
CYGWIN_V15_WIN32API setting without any negative effect.

Sparse issues 68 errors (two errors for each main() function) such

git.c:510:5: error: symbol 'mingw_main' redeclared with different type \
(originally declared at git.c:510) - different argument counts
The errors are caused by the 'main' macro used by the MinGW build
to provide a replacement main() function. The original main function
is effectively renamed to 'mingw_main' and is called from the new
main function. The replacement main is used to execute certain actions
common to all git programs on MinGW (e.g. ensure the standard I/O
streams are in binary mode).
In order to suppress the errors, we change the macro to include the
parameters in the declaration of the mingw_main function.
Unfortunately, this change provokes both sparse and gcc to complain
about 9 calls to mingw_main(), such as the following:
