* child_info.h (child_info::cygheap_h): Delete.

(child_info::dwProcessId): New field.
* cygheap.cc (init_cheap): Delete.
(dup_now): Ditto.
(cygheap_setup_for_child): Ditto.
(cygheap_setup_for_child_cleanup): Ditto.
(cygheap_fixup_in_child): Simplify.  Use new "child_copy" function to copy heap
from parent.
(_csbrk): Don't attempt allocation if within cygheap section.  Fix so that more
than one allocation will succeed.
(cygheap_init): Reset possibly-nonzero region to zero.
* cygheap.h (cygheap_setup_for_child): Delete declaration.
(cygheap_setup_for_child_cleanup): Ditto.
(cygheap_start): Define as an array.
* cygwin.sc: Modernize.  Remove unneeded sections.  Define cygheap here.
* dcrt0.cc (do_exit): Reflect argument change to close_all_files.
* dtable.cc (dtable::vfork_parent_restore): Ditto.
* dtable.h: Ditto.
* fhandler.h: Ditto.
* fork.cc (fork_copy): Call ReadProcessMemory if there is no thread
(indicating that we're execing).
(fork_child): Don't mess with hParent.
(fork_parent): Remove hParent stuff.  It happens earlier now.  Remove call to
cygheap_setup_for_child* stuff.
(fork): Put child_info_stuff in grouped structure.  Issue error if parent
handle is not set.
(child_copy): New function.
* sigproc.cc (child_info::child_info): Put cygheap settings here.  Set parent
handle.
(child_info::~child_info): Close parent handle if it exists.
* spawn.cc (spawn_guts): Reorganize so that ciresrv is allocated at only the
last minute so that cygheap changes are reflected.  Delete cygheap_setup*
calls.
* syscalls.cc (close_all_files): Add an argument to flag when the fd entry
should be released.
* winsup.h (close_all_files): Add an argument to close_all_files declaration.
Declare child_copy.
