Sort the syscalls.mk files, give all generated files the same header. No non-comment changes to the .S files. Change-Id: Iafcfd004c3ea92b64268f80ab16df615b97cefac

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. Change-Id: I9354d2e0dc47c689296a34b5b229fc9ba75f1a83

Switch x86 syscall stubs over to the ENTER/END style of the ARM stubs. Also update the x86 asm.h to support this; we need it for libm assembler anyway. Also clean up the _FBSDID hack in <sys/cdefs.h>. Change-Id: Iababd977b8110ec022bf7c93f4d62ece47630e7c

Fix x86 cfi directives for syscalls. The syscall generation always used 4 bytes for each push cfi directive. However, the first push should always use an offset of 8 bytes, each subsequent push after that is only 4 bytes though. Change-Id: Ibaabd107f399ef67010b9a08213783957c2f74a9

Ensure __set_errno is still visible on LP32. The use of the .hidden directive to avoid going via the PLT for __set_errno had the side-effect of actually making __set_errno hidden (which is odd because assembler directives don't usually affect symbols defined in a different file --- you can't even create a weak reference to a symbol that's defined in a different file). This change switches the system call stubs over to a new always-hidden __set_errno_internal and has a visible __set_errno on LP32 just for binary compatibility with old NDK apps. (cherry-pick of 7efad83d430f4d824f2aaa75edea5106f6ff8aae.) Bug: 17423135 Change-Id: I6b6d7a05dda85f923d22e5ffd169a91e23499b7b
