Determines if a process exists based on the pid. (proc_exists (_pinfo *p): Use new proc_exists function above. (proc_subproc): Copy pinfo stuff around rather than _pinfo pointers. Try to be careful about releasing shared memory when we don't need it anymore. Remove pinfo locks. (remove_zombies): Remove pinfo memory when zombie is going away. * sigproc.h: Reflect _pinfo/pinfo changes in sigproc.cc. * spawn.cc (spawn_guts): Eliminate pinfo *child argument. Reorganize to only initialize child pinfo after process has been started and we know the windows pid. (_spawnve): Reflect spawn_guts changes. * syscalls.cc (setpgid): Use pinfo constructor to access process info. (getpgid): Ditto. (internal_getlogin): Use _pinfo. * winsup.h: Eliminate pinfo_mutex. Eliminate spawn_guts declaration since it is static now. Reflect set_myself argument change. * include/sys/cygwin.h: Add some PID_* enums to accomodate new pinfo stuff. * include/cygwin/version.h: Update minor version for cygdrive changes below.
