Add signalfd() call to bionic. Adding the signalfd call was done in 3 steps: - add signalfd4 system call (function name and syscall number) to libc/SYSCALLS.TXT - generate all necessary headers by calling libc/tools/gensyscalls.py. This patch is adding the generated files since the build system does not call gensyscalls.py. - create the signalfd wrapper in signalfd.cpp and add the function prototype to sys/signalfd.h (cherry-pick of 0c11611c11f4dc1b6d43587b72c3ccbe8c51a51c, modified to work with older versions of GCC still in use on some branches.)
