Use mmap(2) emulation for buffer text on MS-Windows.
src/Makefile.in (C_HEAP_SWITCH): Get the predefined heap size from
configure.
(ADDSECTION, MINGW_TEMACS_POST_LINK): Remove, no longer used.
src/lisp.h (NONPOINTER_BITS): Modify the condition to define to zero
for MinGW, since it no longer uses gmalloc.
src/buffer.c: Do not define mmap allocations functions for Windows.
Remove mmap_find which is unused. Remove mmap_set_vars which does
nothing useful.
[WINDOWSNT]: Include w32heap.h.
(init_buffer): Always allocate new memory for buffers.
src/emacs.c: Remove mmap_set_vars calls.
src/image.c (free_image): Undef free for Windows because it is
redirected to our private version.
src/unexw32.c (COPY_PROC_CHUNK): Use %p format for 64bits
compatibility.
(copy_executable_and_dump_data): Remove dumping the heap section.
(unexec): Restore using_dynamic_heap after dumping.
src/w32heap.c (dumped_data_commit, malloc_after_dump)
(malloc_before_dump, realloc_after_dump, realloc_before_dump)
(free_after_dump, free_before_dump, mmap_alloc, mmap_realloc)
(mmap_free): New functions.
src/w32heap.h: Declare dumped_data and mmap_* function prototypes.
nt/inc/ms-w32.h: Switch to the system heap allocation scheme
instead of GNU malloc and ralloc.
nt/inc/sys/mman.h: New file.
nt/INSTALL: Update for the new build requirements.
etc/NEWS: Mention build changes on MS-Windows.
configure.ac (C_HEAP_SWITCH) define for different values of
dumped heap size depending on 32/64bits arch on Windows.
Don't check for pthreads.h on MinGW32/64, it gets in the way.
Use mmap(2) for buffers and system malloc for MinGW32/64.
