Consolidate preadv/preadv64 implementation
This patch consolidates all the preadv{64} implementation for Linux
in only one (sysdeps/unix/sysv/linux/preadv{64}.c). It also removes the
syscall from the auto-generation using assembly macros.
It was based on previous pread/pread64 consolidation patch. The new macro
SYSCALL_LL{64} is used to handle the offset argument and alias is created
for __ASSUME_OFF_DIFF_OFF64 in case of pread64.
Checked on x86_64, i386, aarch64, and powerpc64le.
* misc/Makefile (CFLAGS-preadv.c): New variable: add cancellation
required flags.

* sysdeps/unix/sysv/linux/wordsize-64/preadv64.: Likwise.
* sysdeps/unix/sysv/linux/x86_64/x32/syscalls.list (preadv): Remove
syscall from auto-generation.
* sysdeps/unix/sysv/linux/preadv.c: Rewrite implementation.
[WORDSIZE == 64] (preadv64): Remove macro.
[!PREADV] (PREADV): Likewise.
[!PREADV] (PREADV_REPLACEMENT): Likewise.
[!PREADV] (PREAD): Likewise.
[!PREADV] (OFF_T): Likewise.
[!__ASSUME_PREADV] (PREADV_REPLACEMENT): Likewise.
(LO_HI_LONG): Remove macro.
[__WORDSIZE != 64 || __ASSUME_OFF_DIFF_OFF64] (preadv): Add function.
* sysdeps/unix/sysv/linux/preadv64.c: Rewrite implementation.
(PREADV): Remove macro.
(PREADV_REPLACEMENTE): Likewise.
(PREAD): Likewise.
(OFF_T): Likewise.
(preadv64): New function.
* nptl/tst-cancel4.c (tf_preadv): Add test.
