* exceptions.cc (setup_handler): Move non-interruptible condition handling
(back) to wait_sig (as suggested by Pierre Humblet).
(set_process_mask): Don't worry about calling sig_dispatch_pending from
sigthread since it is detected in the function anyway.
(sig_handle): Eliminate thisproc arg. Don't call sig_dispatch_pending on
SIGCONT since that should happen automatically.
* sigproc.cc (sig_dispatch_pending): Eliminate justwake argument. Just return
when called from sigthread.
(wait_sig): Change some variables to bool. Change inner while to an if. Move
uninterruptible signal handling here.
(sigproc_terminate): Don't call sig_dispatch_pending. Just increment semaphore
on exit.
* speclib: Use slightly different (but still flawed) method for determining
symbols to extract from libraries.
DRIVE_REMOVABLE.
* fhandler.cc (fhandler_base::lseek): Be more paranoid when constructing
offsets from 64 bit value.
* syscalls.cc (logout): Avoid temp buffer memcpy since new scheme does not
require it.
(utmp_data): Rework as a macro which returns a pointer into a buffer.
(getutent): Use new buffer allocation mechanism to grab a utmp buffer.
(getutid): Ditto.
(pututline): Ditto.
end of directory condition is encountered as per SUSv2.

* fhandler_tty.cc (fhandler_tty_slave::open): Adjust console open handle
counter regardless of whether this is a pty or tty.
(fhandler_tty_slave::open): Ditto.
(fhandler_tty_slave::dup): Ditto.
(fhandler_tty_common::set_close_on_exec): Ditto.
(fhandler_tty_master::init_console): Decrement console open handle counter
after init since it will now be handled by all tty open.
* syscalls.cc (setsid): Rework debugging output slightly.
value for tokens.
* syscalls.cc (seteuid32): Ditto. Set new_token to process token if
process token is suitable.
* uinfo.cc (uinfo_init): Initialize tokens in cygheap user info
to INVALID_HANDLE_VALUE.
* cygheap.h (enum impersonation): Delete.
(cygheap_user::impersonation_state): Delete.
(cygheap_user::current_token): New.
(cygheap_user::issetuid): Modify to use current_token.
(cygheap_user::token): Ditto.
(cygheap_user::deimpersonate): Ditto.
(cygheap_user::reimpersonate): Ditto.
(cygheap_user::has_impersonation_tokens): Ditto.
(cygheap_user::close_impersonation_tokens): Ditto.
* security.cc (cygwin_set_impersonation_token): Always set the token.
(verify_token): Change type of gsid to cygpsid.
(get_file_attribute): Use the effective ids.
* syscalls.cc (seteuid32): Modify to use cygheap_user::current_token.
* uinfo.cc (uinfo_init) Do not set cygheap->user.impersonation_state.
(ccalloc): Only issue system_printf when debugging.
* dtable.cc (dtable::extend): Only allocate 100 * the incremental growth size
max. Set errno appropriately.
(dtable::build_fhandler): Check for error from set_name.
* fhandler.cc (fhandler_base::set_name): Set errno and return error on OOM.
* fhandler.h (fhandler_base::set_name): Change to bool.
* fhandler_process.cc (format_process_stat): Fix formatting.
* resource.cc (getrlimit): Return greater of OPEN_MAX or fd table size.
* sysconf.cc (sysconf): Ditto.
length back to munmap(). Evaluate intersection between given
area and mapped area and return it, if any.
(mmap64): On regular files, don't allow mappings beginning beyond
EOF. Return with errno set to ENXIO instead.
(munmap): Rewrite SUSv3 conformant. Check if given memory area is
valid. Unmap all maps inside given memory area. Don't return error
if no mapping has been unmapped.
return socket connection state.
* fhandler_socket.cc (dup): Copy socket connect state to new file
handle.
* net.cc (cygwin_rcmd): Mark file handles of sockets returned by
rcmd() as CONNECTED state.
(cygwin_rexec): Similarly for rexec().
(socketpair): Mark both ends of a new socket pair as CONNECTED.
