option handling to use the same style throughout all Cygwin utils.
Throughout use program_invocation_short_name to refer to current
process name in Cygwin executables.
* utils.sgml: Align documentation to above change. Add missing
sections for getconf, ldd, and setmetamode.
* strace.cc (proc_child): Avoid compiler warning.
(sys_sigabbrev): New array of signal strings, patterned after linux.
(siglist): Use __signals.
* cygwin/include/cygwin/signal.h (sys_sigabbrev): Define.
* cygwin/include/cygwin/version.h: Bump API minor version to 177.
* utils/Makefile.in (kill.exe): Remove reliance on libiberty.
* utils/kill.cc (strsigno): New function patterned after libiberty but using
newly exported cygwin array.
* kill.cc (forcekill): Do not pass negative pids to
cygwin_internal. Check if sig == 0. Improve error messages.
(main): Make pid a long long and distinguish between pids, gpids
(i.e. negative pids) and Win9x pids.
* kill.cc (longopts): New.
(opts): Ditto.
(get_sig): Accept const char * parameter. Return -1 on unknown signal.
(test_for_unknown_sig): New function.
(listsig): New function.
(main): Use getopt_long for option parsing. Implement -l, and -s options. Use
test_for_unknown_sig() to test for signal validity.
more obvious.
* strace.cc (add_child): Just add child's pid directly.
(remove_child): No need to close the child process pid since ContinueDebugEvent
does that automatically.
(proc_child): Ditto for child thread.
cygwin process after waiting 2 tenths of a second for it to terminate.
(forcekill): Add an extra argument determining whether to wait for the process
to exit.
(forcekill): New function.
* ps.cc (main): Add '-W' option to list Windows pids as well as Cygwin pids.
(dummyprocessmodules): New function.
(GetModuleFileNameEx95): New function.
(init_win): New function.
(to_time_t): New function.
