* dcrt0.cc (dll_crt0_0): Call mmap_init.
* external.cc (cygwin_internal): Call getpagesize instead of getshmlba.
* fhandler.h (fhandler_base::mmap): Change access to prot parameter.
(fhandler_base::fixup_mmap_after_fork): Ditto.
(fhandler_disk_file::mmap): Ditto.
(fhandler_disk_file::fixup_mmap_after_fork): Ditto.
(fhandler_dev_mem::mmap): Ditto.
(fhandler_dev_mem::fixup_mmap_after_fork): Ditto.
* fhandler_mem.cc (fhandler_dev_mem::write): Call getsystempagesize
instead of getpagesize.
(fhandler_dev_mem::read): Ditto.
(fhandler_dev_mem::fstat): Ditto.
(fhandler_dev_mem::mmap): Move to mmap.cc.

Take advantage of pagesize==granularity.
(gen_protect): New static function to evaluate Windows
protection bits from POSIX protection and flags.
(gen_access): Ditto for Windows access mode.
(VirtualProt9x): Wrapper function to call VirtualProtect on 9x.
(VirtualProtNT): Ditto for NT.
(VirtualProtEx9x): Ditto for VirtualProtectEx on 9x.
(VirtualProtExNT): Ditto for NT.

(MapViewNT): Ditto for NT.
(mmap_funcs_9x): Structure containing function pointers to wrapper
functions for 9x.
(mmap_funcs_nt): Ditto for NT.
(mmap_func): Pointer to wrapper functions used in subsequent code.
(mmap_init): Initialize mmap_func depending on OS.
(class mmap_record): Use sensible member names. Add POSIX protection
member. Drop Windows access flags member. Constify more methods.
Use accessors instead of direct member access inside of own methods.
(mmap_record::gen_protect): Class wrapper to evaluate matching
Windows protection bits.

(mmapped_areas): Convert from pointer to global struct.
(mmap_record::alloc_page_map): Simplify.
(mmap_record::map_pages): Ditto.
(mmap_record::fixup_page_map): Delete.
(mmap64): Simplify. Add workaround for Windows 98 bug. Fix bug on
NT that existing anonymous mappings weren't searched for a match.
(munmap): Add workaround for Windows 98 bug.
(msync): Simplify.
(mprotect): Handle existing maps correctly.
(mlock): Add local pagesize variable and enlightening comment.
(fhandler_disk_file::mmap): Main functionality now in CreateMapping/
MapView wrapper functions.
(fhandler_disk_file::fixup_mmap_after_fork): Call MapView wrapper.
(fhandler_dev_mem::mmap): Moved from fhandler_mem.cc. Simplify by
calling MapViewNT.

(fhandler_dev_mem::msync): Ditto.
(fhandler_dev_mem::fixup_mmap_after_fork): Ditto. Call MapViewNT.
(fixup_mmaps_after_fork): Restructure and hopefully speed up loop for
setting protection and memory content on MAP_PRIVATE maps.

(AT_EXTENDABLE_FILE): Add define.
(NtCreateSection): Add prototype.
* syscalls.cc (getpagesize): Return granularity as pagesize now.
(getsystempagesize): New function to retrieve "real" pagesize.
(getshmlba): Delete since it's replaced by getpagesize now.
* wincap.h (wincaps::has_mmap_alignment_bug): New element.
* wincap.cc: Implement above element throughout.
* winsup.h (getshmlba): Drop prototype.
