Sort the syscalls.mk files, give all generated files the same header. No non-comment changes to the .S files. Change-Id: Iafcfd004c3ea92b64268f80ab16df615b97cefac 2013-10-16 23:27:59 +02:00			`/* Generated by gensyscalls.py. Do not edit. */`

Stop using the non-uapi <linux/err.h> header file. We only need it for MAX_ERRNO, and it's time we had somewhere to put the little assembler utility macros we've been putting off writing.

Add signalfd call to bionic 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.)
