Replaces Windows "ANSI" APIs dealing with file- or path names with their
Unicode equivalent, adding UTF-8/UTF-16LE conversion as necessary.
The dirent API (opendir/readdir/closedir) is updated in a separate commit.
Adds trivial wrappers for access, chmod and chdir.
Adds wrapper for mktemp (needed for both mkstemp and mkdtemp).
The simplest way to convert a repository with legacy-encoded (e.g. Cp1252)
file names to UTF-8 ist to checkout with an old msysgit version and
"git add --all & git commit" with the new version.

Add Unicode conversion functions to convert between Windows native UTF-16LE
encoding to UTF-8 and back.
To support repositories with legacy-encoded file names, the UTF-8 to UTF-16
conversion function tries to create valid, unique file names even for
invalid UTF-8 byte sequences, so that these repositories can be checked out
without error.
The current implementation leaves invalid UTF-8 bytes in range 0xa0 - 0xff
as is (producing printable Unicode chars \u00a0 - \u00ff, equivalent to
ISO-8859-1), and converts 0x80 - 0x9f to hex-code (\u0080 - \u009f are
control chars).
The Windows MultiByteToWideChar API was not used as it either drops invalid
UTF-8 sequences (on Win2k/XP; producing non-unique or even empty file
names) or converts them to the replacement char \ufffd (Vista/7; causing
ERROR_INVALID_NAME in subsequent calls to file system APIs).

Winansi.c has many static variables that are accessed and modified from
the [v][f]printf / fputs functions overridden in the file. This may cause
multi threaded git commands that print to the console to produce corrupted
output or even crash.
Additionally, winansi.c doesn't override all functions that can be used to
print to the console (e.g. fwrite, write, fputc are missing), so that ANSI
escapes don't work properly for some git commands (e.g. git-grep).
Instead of doing ANSI emulation in just a few wrapped functions on top of
the IO API, let's plug into the IO system and take advantage of the thread
safety inherent to the IO system.
Redirect stdout and stderr to a pipe if they point to the console. A
background thread reads from the pipe, handles ANSI escape sequences and
UTF-8 to UTF-16 conversion, then writes to the console.
The pipe-based stdout and stderr replacements must be set to unbuffered, as
MSVCRT doesn't support line buffering and fully buffered streams are
inappropriate for console output.
Due to the byte-oriented pipe, ANSI escape sequences and multi-byte UTF-8
sequences can no longer be expected to arrive in one piece. Replace the
string-based ansi_emulate() with a simple stateful parser (this also fixes
colored diff hunk headers, which were broken as of commit 2efcc977).
Override isatty to return true for the pipes redirecting to the console.
Exec/spawn obtain the original console handle to pass to the next process
via winansi_get_osfhandle().
All other overrides are gone, the default stdio implementations work as
expected with the piped stdout/stderr descriptors.
Global variables are either initialized on startup (single threaded) or
exclusively modified by the background thread. Threads communicate through
the pipe, no further synchronization is necessary.
The background thread is terminated by disonnecting the pipe after flushing
the stdio and pipe buffers. This doesn't work for anonymous pipes (created
via CreatePipe), as DisconnectNamedPipe only works on the read end, which
discards remaining data. Thus we have to setup the pipe manually, with the
write end beeing the server (opened with CreateNamedPipe) and the read end
the client (opened with CreateFile).
Limitations: doesn't track reopened or duped file descriptors, i.e.:
- fdopen(1/2) returns fully buffered streams
- dup(1/2), dup2(1/2) returns normal pipe descriptors (i.e. isatty() =
false, winansi_get_osfhandle won't return the original console handle)
Currently, only the git-format-patch command uses xfdopen(xdup(1)) (see
"realstdout" in builtin/log.c), but works well with these limitations.

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).

Correct all hits from

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
operators have a SP around it when necessary.
We usually refrain from making this kind of a tree-wide change in
order to avoid unnecessary conflicts with other "real work" patches,
but in this case, the end result does not have a potentially
cumbersome tree-wide impact, while this is a tree-wide cleanup.
Fixes to compat/regex/regcomp.c and xdiff/xemit.c are to replace a

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,
