Ramsay Jones	15b7f601fc	compat/win32mmap.c: Fix some sparse warnings Sparse issues two 'Using plain integer as NULL pointer' warnings against the call to the CreateFileMapping() function. The warnings relate to the second and sixth parameters, which both have pointer type. In order to suppress the warnings, we simply pass the NULL pointer, rather than '0', to those parameters in the function call.

Ian McLean	60890cc60c	Fix "Out of memory? mmap failed" for files larger than 4GB on Windows The git_mmap implementation was broken for file sizes that wouldn't fit into a size_t (32 bits). This was caused by intermediate variables that were only 32 bits wide when they should be 64 bits.

Ramsay Jones	b1b952043f	MSVC: Add support for building with NO_MMAP When the NO_MMAP build variable is set, the msvc linker complains: error LNK2001: unresolved external symbol _getpagesize The msvc libraries do not define the getpagesize() function, so we move the mingw_getpagesize() implementation from the conditionally built win32mmap.c file to mingw.c.

Janos Laube	b130a72b27	MinGW: implement mmap Add USE_WIN32_MMAP which triggers the use of windows' native file memory mapping functionality in git_mmap()/git_munmap() functions. As git functions currently use mmap with MAP_PRIVATE set only, this implementation supports only that mode for now. On Windows, offsets for memory mapped files need to match the allocation granularity. Take this into account when calculating the packed git- windowsize and file offsets. At the moment, the only function which makes use of offsets in conjunction with mmap is use_pack() in sha1-file.c. Git fast-import's code path tries to map a portion of the temporary packfile that exceeds the current filesize, i.e. offset+length is greater than the filesize. The NO_MMAP code worked with that since pread() just reads the file content until EOF and returns gracefully, while MapViewOfFile() aborts the mapping and returns 'Access Denied'. Working around that by determining the filesize and adjusting the length parameter.
