* cygheap.h (init_cygheap): Move heap pointers here.

Browse Source 
* include/sys/cygwin.h (perprocess): Remove heap pointers.
* dcrt0.cc (__cygwin_user_data): Reflect obsolete perprocess stuff.
(_dll_crt0): Don't initialize heap pointers.
(cygwin_dll_init): Ditto.
(release_upto): Use heap pointers from cygheap.
* heap.h: Ditto.
* fork.cc (fork_parent): Ditto.  Don't set heap pointers in ch.
(fork_child): Remove obsolete sigproc_fixup_after_fork.
* shared.cc (memory_init): Reorganize so that cygheap initialization is called
prior to regular heap since regular heap uses cygheap now.
* sigproc.cc (proc_subproc): Eliminate zombies allocation.
(sigproc_init): Move zombies alloation here.  Don't free up array on fork, just
reuse it.
(sigproc_fixup_after_fork): Eliminate.
* sigproc.h: Ditto.
* include/cygwin/version.h: Reflect change to perprocess structure.
