Commit 95e38b37 ("add support for systems without legacy setrlimit/getrlimit
syscalls") has added use of the prlimit64 syscall in getrlimit and setrlimit
functions. This change causes memory corruption on getrlimit call for 32-bit
CPUs like ARC, as ARC doesn't have ugetrlimit syscall and uses prlimit64.
Also, setrlimit has been broken by prlimit64 call on 32-bit CPUs like, i386,
ARM, ARC.
For the prlimit64 syscall the kernel expects an rlimit struct with 64-bit fields,
but on 32-bit CPUs without _FILE_OFFSET_BITS=64 the struct rlimit has 32-bit
fields.
Add safe implementations of getrlimit, setrlimit, prlimit for 32-bit CPUs with a
local struct rlimit64 variable for use in the prlimit64 syscall.
For 64-bit CPUs and configurations with _FILE_OFFSET_BITS=64 use
getrlimit, setrlimit, prlimit as aliases to getrlimit64, setrlimit64 and
prlimit64. Add a new function prlimit64.
Tested on aarch64, arm, i386, arc.

This borrows getloadavg.c from musl.
getloadavg pops up often. Recently llvm and rust are dependent on it.
glibc and musl have it and no-one actually checks if it's available in your libc.
It's just become way easier to add it in uclibc-ng rather than patch everything else.

- use the provided __res_state() method instead of direct access
to struct __res_state pointer &_res/*__resp
- change the __UCLIBC_HAS_TLS__ protected __res_state() implementation
to the one where the comment 'When threaded, _res may be a per-thread
variable.' indicates this should be used with threads/TLS enabled
Fixes the following segfaults with buildroot raspberrypi3_64_defconfig

Since Linux 3.11, O_TMPFILE allows to create unnamed files that can be
linked later on. It is internally defined as (O_TMPFILE | O_DIRECTORY)
to make it fail on old kernels.
Copying definitions from glibc for O_TMPFILE is not enough to support
O_TMPFILE; The open() wrapper also need to pass the mode when the flag
contains O_TMPFILE, otherwise, it will pass mode 000 which will succeed
but yield unexpected results.
openat() is curiously not affected since it passes the mode
unconditionally..

This commit adds support for Kalray VLIW family (kvx)
Kalray kv3 core is embedded in Kalray Coolidge SoC. This core which is the
third of the KV family has the following features:
32/64 bits execution mode
6-issue VLIW architecture
64 x 64bits general purpose registers
SIMD instructions
little-endian
In order to build a usable toolchain, build scripts are provided at the
following address: https://github.com/kalray/build-scripts.
Kalray uses FOSS which is available at https://github.com/kalray
This includes Linux kernel, uClibc-ng, gcc, binutils, etc.

Follow the steps to build c-sky uclibc linux system:
1. git clone https://github.com/c-sky/buildroot.git
2. cd buildroot
3. make qemu_csky_ck810_uclibc_defconfig
4. make
Follow the buildroot/board/qemu/csky/readme.txt to run.
This buildroot toolchain is pre-build, But you can rebuild
the c-sky uclibc-ng alone and install it to the buildroot
sysroot manually.
We'll try our best to improve the uclibc-ng continuously.

The recvmmsg and sendmmsg is very important for UDP stream application.
If we only use recvmsg for UDP stream, it will only copy one mtu size
of data in a syscall. And recvmmsg copy as many as you want in a syscall.
So recvmmsg is more efficient,and some applications will depends on the
recvmmsg and sendmmsg, eg: UDP media stream player.
