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().

In particular, while linking test-svn-fe.exe, the linker complains
that the external symbol _strtoull is unresolved. A call to this
function was added in commit ddcc8c5b ("vcs-svn: skeleton of an svn
delta parser", 25-12-2010).
The NO_STRTOULL build variable attempts to provide support to old
systems which can't even declare 'unsigned long long' variables,
let alone provide the strtoll() or strtoull() functions. Setting
this build variable does not provide an implementation of these
functions. Rather, it simply allows the compat implementations
of strto{i,u}max() to use strtol() and strtoul() instead.
In order to fix the linker error on systems with NO_STRTOULL set,
currently MSVC and OSF1, we can substitute a call to strtoumax().
However, we can easily provide support for the strtoull() and
strtoll() functions on MSVC, since they are essentially already
available as _strtoui64() and _strtoi64(). This allows us to
remove NO_STRTOULL for MSVC.

va_copy is C99. We have avoided using va_copy many times in the past,
which has led to a bunch of cut-and-paste. From everything I found
searching the web, implementations have historically either provided
va_copy or just let your code assume that simple assignment of worked.
So my guess is that this will be sufficient, though we won't really
know for sure until somebody reports a problem.

In particular, the following warning is issued while compiling
compat/msvc.c:
...mingw.c(223) : warning C4133: 'function' : incompatible \
types - from '_stati64 *' to '_stat64 *'
which relates to a call of _fstati64() in the mingw_fstat()
function definition.
This is caused by various layers of macro magic and attempts to
avoid macro redefinition compiler warnings. For example, the call
to _fstati64() mentioned above is actually a call to _fstat64(),
and expects a pointer to a struct _stat64 rather than the struct
_stati64 which is passed to mingw_fstat().
The definition of struct _stati64 given in compat/msvc.h had the
same "shape" as the definition of struct _stat64, so the call to
_fstat64() does not actually cause any runtime errors, but the
structure types are indeed incompatible.
In order to avoid the compiler warning, we add declarations for the
mingw_lstat() and mingw_fstat() functions and supporting macros to
msvc.h, suppressing the corresponding declarations in mingw.h, so
that we can use the appropriate structure type (and function) names
from the msvc headers.

Centralize the include of windows.h in git-compat-util.h, turn on
WIN32_LEAN_AND_MEAN to avoid including plenty of other header files
which is not needed in Git. Also ensure we load winsock2.h first,
so we don't load the older winsock definitions at a later stage,
since they contain duplicate definitions.
When moving windows.h into git-compat-util.h, we need to protect
the definition of struct pollfd in mingw.h, since this file is used
by both MinGW and MSVC, and the latter defines this struct in
winsock2.h.
We need to keep the windows.h include in compat/win32.h, since its
shared by both MinGW and Cygwin, and we're not touching Cygwin in
this commit. The include in git-compat-util.h is protected with an
ifdef WIN32, which is not the case when compiling for Cygwin.
