* include/cygwin/version.h: Bump DLL minor version number to 5 due to all of

the changes below.  Redefine process structure to avoid a fixed size table.
Redefine pinfo/_pinfo classes.  Use these throughout.
* dcrt0.cc (dll_crt0_1): Accomodate set_myself argument change.
(__api_fatal): Accomodate _pinfo::record_death argument change.
* exceptions.cc (really_exit): Ditto.
(sig_handle_tty_stop): Use pinfo constructor to access process info.
(events_init): Don't create pinfo_mutex since it is no longer required.
* external.cc (fillout_pinfo): Use winpids class to iterate over all system
pids.
(cygwin_internal): lock_pinfo_for_update and unlock_pinfo are now noops.
* fhandler_termios.cc (fhandler_termios::set_ctty): Use pinfo constructor to
access process info.
* fork.cc (fork): Reorganize to initialize child info after the child has
started since that is when we know the child's winpid, which is necessary to
allocate the pinfo shared memory.
* mmap.cc (recreate_mmaps_after_fork): Change arg type to _pinfo.
* pinfo.cc: Rename pinfo methods to _pinfo throughout.  Eliminate pinfo_list
stuff.
(set_myself): Accept a pid argument now.  Call pinfo initializer to initialize
myself.  Detect when this is an "execed" process and create an "indirect" pid
block.
(pinfo_init): Accomodate set_myself arg change.
(procinfo): Remove.
(pinfo::lock_pinfo): Remove.
(pinfo::unlock_pinfo): Remove.
(pinfo::init): New method.  Allocates shared memory space for process pinfo
structure.
(pinfo::record_death): Don't call locking functions.
(cygwin_winpid_to_pid): Simplify by using new pinfo constructor.
(EnumProcessesW95): New function for iterating over processes on Windows 95.
(winpids::winpids): New constructor for winpids class.  Sets up a list of
process ids.
(enum_init): Initialize w95/wnt pid enumerators.
* shared.cc (shared-info::initialize): Remove pid initialization.
* shared.h: Move pinfo stuff into pinfo.h.
(class shared_info): Remove pinfo_list element.
* signal.cc (kill_worker): Use pinfo constructor to access process info.
(kill_pgrp): Ditto.  Use winpids methods to access list of processes.
* sigproc.cc: Throughout, modify to use _pinfo where appropriate.
(proc_exists (pid_t)): New function.  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.
