* Makefile.in: Build wincap.o.
* wincap.cc: New file.
* wincap.h: Ditto.
* autoload.cc: Add dynamic load statement for `CreateHardLinkA'.
* dcrt0.cc (os_being_run): Eliminated.
(osname): Ditto.
(iswinnt): Ditto.
(set_os_type): Ditto.
(dll_crt0_1): Call wincap.init() instead of set_os_type().
(_dll_crt0): Ditto.
* environ.cc (set_chunksize): New function.
(parse_thing): `forkchunk' setting now invokes function `set_chunksize'.
* fork.cc (chunksize): Eliminated. Moved to be member of wincap.
* host_dependent.h: Removed.
* syscalls.cc (_link): Try using `CreateHardLinkA' first, if available.
* cygheap.cc, dcrt0.cc, delqueue.cc, dir.cc,
environ.cc, fhandler.cc, fhandler.h, fhandler_console.cc,
fhandler_mem.cc, fork.cc, mmap.cc, net.cc, pinfo.cc, pinfo.h,
security.cc, syscalls.cc, sysconf.cc, syslog.cc, thread.cc,
times.cc, tty.cc, uinfo.cc, uname.cc, winsup.h: Use new wincap
capability check throughout.
* winsup.h: Include wincap.h. Eliminate extern declarations of
`os_being_run' and `iswinnt'. Eliminate `os_type" definition.
* include/cygwin/version.h: Bump version to 1.3.4.
