* cygheap.h (cygheap_types): Add HEAP_COMMUNE.

Browse Source 
* fhandler_proc.cc: Use cygheap rather than user heap for allocation of filebuf
throughout.
* fhandler_registry.cc: Ditto.
* fhandler_virtual.cc: Ditto.
* fhandler_process.cc: Ditto.
(get_mem_values): Use malloc/realloc/free rather than new.
* pinfo.cc (_pinfo::commune_send): Allocate on cygwin heap rather than user
heap.  Avoid calling ReadFile when correct number of characters have been read
or suffer buffer corruption.

(_pinfo::fds): Ditto.
(_pinfo::root): Ditto.
(_pinfo::cwd): Ditto.
(_pinfo::cmdline): Ditto.
