Linux: Move timer_settime, __timer_settime64 from librt to libc
The symbols were moved using scripts/move-symbol-to-libc.py. The way the ABI intransition is implemented is changed with this commit: the implementation is now consolidated in one file with a TIMER_T_WAS_INT_COMPAT check. The shared librt is now empty, so this commit adds a placeholder symbol at the base version, GLIBC_2.2, and potentially at the GLIBC_2.3.3 version as well (the leftover from the int/timer_t ABI transition).

Add libc ABI extension kludge for baseline-violating libdl symbols
Some targets have a GLIBC_2.0 baseline for libdl, while using GLIBC_2.2 for libc. This means that the generated libc.map file does not have any version nodes for GLIBC_2.0 or GLIBC_2.1. However, moving symbols from libdl into libc needs such version nodes. (Future symbol moves from librt will need this as well.) This kludge is only necessary for symbols predating GLIBC_2.2 because the affected targets use GLIBC_2.2 as the baseline for libc. Given the small number and fixed set of affected architectures, no generic mechanism is implemented, and instead the map file fragment is hard-coded in scripts/versions.mk. The compat_symbol macro already emits the appropriate version strings, so no adjustments are needed there. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org> |

Revert {send,sendm,recv,recvm}msg conformance changes
After some discussion in libc-alpha about this POSIX compliance fix, I see
that GLIBC should indeed revert back to previous definition of msghdr and
cmsghdr and implementation of sendmsg, recvmsg, sendmmsg, recvmmsg due some
reasons:
* The possible issue where the syscalls wrapper add the compatibility
layer is quite limited in scope and range. And kernel current
also add some limits to the values on the internal msghdr and
cmsghdr fields:
- msghdr::msg_iovlen larger than UIO_MAXIOV (1024) returns
EMSGSIZE.
- msghdr::msg_controllen larger than INT_MAX returns ENOBUFS.
* There is a small performance hit for recvmsg/sendmsg/recmmsg which
is neglectable, but it is a big hit for sendmmsg since now instead
of calling the syscall for the packed structure, GLIBC is calling
multiple sendmsg. This defeat the very existence of the syscall.
* It currently breaks libsanitizer build on GCC [1] (I fixed on compiler-rt).
However the fix is incomplete because it does add any runtime check
since libsanitizer currently does not have any facility to intercept
symbols with multiple version [2].
This, along with incorret dlsym/dlvsym return for versioned symbol due
another bug [3], makes hard to interpose versioned symbols.
Also, current approach of fixing GCC PR#71445 leads to half-baked
solutions without versioned symbol interposing.
This patch basically reverts commits

network: recvmsg and sendmsg standard compliance (BZ#16919)
POSIX specifies that both msghdr::msg_iovlen and msghdr::msg_controllen to be of size int and socklen_t respectively. However Linux defines it as both size_t and for 64-bit it requires some adjustments to make the functions standard compliance. This patch fixes it by creating a temporary header and zeroing the pad fields for 64-bits architecture where size of size_t exceeds the size of the int. Also the new recvmsg and sendmsg implementation is only added on libc, with libpthread only containing a compat symbol. Tested on x86_64, i686, aarch64, armhf, and powerpc64le. * conform/data/sys/socket.h-data (msghdr.msg_iovlen): Remove xfail- and change to correct expected type. (msghdr.msg_controllen): Likewise.
