* perthread.h (vfork_save): Add ctty, sid, pgid, exitval fields.
(vfork_save::restore_pid): New method. (vfork_save::restore_exit): New method. * fork.cc (vfork): Save ctty, sid, pgid and restore them when returning to "parent". Use exitval field if exiting but never created a new process. * syscalls.cc (setsid): Detect when in "vfork" and force an actual fork so that pid will be allocated (UGLY!). (getsid): New function. * dcrt0.cc (do_exit): Use vfork_save::restore_exit method for returning from a vfork. * spawn.cc (spawnve): Use vfork_save::{restore_pid,restore_exit} methods for returning from vfork. * cygwin.din: Export getsid. * include/cygwin/version.h: Bump api minor number. * malloc.cc: #ifdef sYSTRIm for when MORECORE_CANNOT_TRIM is true.
