Consolidate posix_fallocate{64} implementations
This patch consolidates all the posix_fallocate{64} implementation for Linux in only one (sysdeps/unix/sysv/linux/posix_fallocate{64}.c). It also removes the syscall from the auto-generation using assembly macros. The macro SYSCALL_LL{64} is used to handle the offset argument along with the new INTERNAL_SYSCALL_CALL macro to define correct argument count for internal INTERNAL_SYSCALL call. Tested on x86_64, i686, x32, aarch64, ppc64le, and armhf. * io/Makefile (tests): Add tst-posix_fallocate and tst-posix_fallocate64. * io/tst-posix_fallocate-common.c: New file. * io/tst-posix_fallocate.c: Likewise. * io/tst-posix_fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/posix_fallocate.c: Remove file. * sysdeps/unix/sysv/linux/mips/mips64/n32/posix_fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fallocate.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/posix_fallocate.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/posix_fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/posix_fallocate.c (posix_fallocate): Use SYSCALL_LL to pass both offset and len arguments. * sysdeps/unix/sysv/linux/posix_fallocate64.c (posix_fallocate64): Likewise. * sysdeps/unix/sysv/linux/x86_64/syscalls.list (pwrite64): Add __libc_pwrite64 alias used by posix_fallocate64.
