* heap.cc (heap_init): Save pointer to end of heap reserved memory.
(sbrk): Don't attempt to commit memory beyond end of heap reserved memory.
Attempt to honor comment and reserve commitbytes if heapchunk fails.
* sigproc.cc (wait_sig): Keep looping if there are more signals to consider and
we are flushing signals.
(sig_send): Put nonsync signals in the correct bucket.
* sigproc.cc (pending_signals): Make static.
(wait_sig): Use defined values rather than integers for rc. Never scan both
todo arrays as this could cause hangs if signals arrive from two different
sources. Rename saw_pending_signals to saw_failed_interrupt. Exit loop when
signal found. Enter low-priority sleep, if necessary, after finished
signalling completion. Set pending_signals when blocked
(from Pierre Humblet).
* 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.
* cygcheck.cc (find_package,list_package): New global
variables.
(usage): Add "--find-package" and "--list-package" options,
reformat output.
(longopts, opts): Add "--find-package" and "--list-package"
options.
(main): Process the "--find-package" and "--list-package"
flags. Add new semantic checks. Add calls to find_package()
and list_package().
* dump_setup.cc: Fix header comment.
(match_argv): Change return type to int to distinguish
between real matches and default ones.
(open_package_list): New static function.
(check_package_files): Factor out opening the package list
file into open_package_list().
(get_packages): New static function.
(dump_setup): Factor out getting a list of packages into
get_packages().
(package_list, package_find): New global functions.
(could_not_access,directory_exists): New static function.
(file_exists): Ditto.
(check_package_files): Ditto.
(dump_setup): Check the contents of each package if check_files is true and
output the result in the "Status" column. Flush output after each package.
* dump_setup.cc (dump_setup): Remove redundant null check. Add informative
message if package info not found.
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_proc.cc (fhandler_proc::readdir): Ditto.
* fhandler_process (fhandler_process::readdir): Ditto.
* fhandler_registry (fhandler_registry::readdir): Ditto.
