* cygwin/strsig.cc (__signals): New macro.

(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.
