preadv/pwritev don't provide separate version for 64-bit wide off_t,
and default to 32-bit wide off_t, which results in a mismatch between
declaration and definition for user programs built with
-D_FILE_OFFSET_BITS=64.
Make offset argument of both functions __off64_t.
This fixes test misc/tst-preadvwritev on xtensa.

Add FDPIC dynamic relocations support, similar to what other FDPIC
targets do.
Lazy binding is implemented in a folllow-up patch.
Disable the SEND* macros because they involve relocations to
access constant strings that are unsupported by the existing
arm version.
Define DL_START, START, ARCH_NEEDS_BOOTSTRAP_RELOCS,
DL_CHECK_LIB_TYPE similarly to what other FDPIC targets do.
Define raise() because _dl_find_hash references __aeabi_uidivmod,
which uses __aeabi_idiv0 which in turn references raise.
* include/elf.h (R_ARM_FUNCDESC): Define.
(R_ARM_FUNCDESC_VALUE): Define.
* ldso/include/dl-string.h (SEND_STDERR, SEND_ADDRESS_STDERR)
(SEND_NUMBER_STDERR): Define empty for __FDPIC__.
* ldso/ldso/arm/dl-inlines.h: New file.
* ldso/ldso/arm/dl-startup.h (PERFORM_BOOTSTRAP_RELOC): Fix type
of load_addr. Fix handling of R_ARM_RELATIVE, add support for
R_ARM_FUNCDESC_VALUE.
(DL_START, START): Define for __FDPIC__.
(raise): Define.
* ldso/ldso/arm/dl-sysdep.h (ARCH_NEEDS_BOOTSTRAP_RELOCS): Define.
(DL_CHECK_LIB_TYPE): Define.
(elf_machine_type_class): Take into account FDPIC related
relocations.
(elf_machine_load_address): Support __FDPIC__.
(elf_machine_relative): Likewise.
* ldso/ldso/arm/elfinterp.c (_dl_linux_resolver): Dummy support
for __FDPIC__, implemented in a later patch.
(_dl_do_reloc): Fix reloc_adr computation for __FDPIC__, fix
handling of local symbols. Fix handling of R_ARM_RELATIVE, add
support for R_ARM_FUNCDESC_VALUE, R_ARM_FUNCDESC.
* ldso/ldso/arm/resolve.S: Make _dl_linux_resolve hidden.
* ldso/ldso/fdpic/dl-inlines.h (htab_delete): Declare.
* libc/sysdeps/linux/arm/bits/elf-fdpic.h: New file, similar to bfin's.
* libc/sysdeps/linux/arm/crtreloc.c: Likewise.
* libc/sysdeps/linux/arm/find_exidx.c (__dl_addr_in_loadaddr) Define.
(find_exidx_callback): Support __FDPIC__.

Like for other FDPIC targets, add defined(__FDPIC__) where needed.
* include/link.h: Include bits/elf-fdpic.h if __FDPIC__ is defined.
(link_map): Use elf32_fdpic_loadaddr if __FDPIC__ is defined.
(dl_phdr_info): Likewise.

__FDPIC__.
* ldso/include/dl-hash.h (elf_resolve): Add funcdesc_ht field if
__FDPIC__ is defined.

OpenBSD arc4random is using chacha20 cipher algorithm for
a long time. This copy is still based on deprecated rc4
cipher algorithm. We could either update the arc4random.c
or drop it. Drop it. Users should better use libbsd when
using arc4random interface. Musl/glibc does not have arc4random
either.

Add NT_GNU_BUILD_ID and other defines to allow applications
using it to successfully compile. (f.e. firefox)

Port over NPTL/TLS support from GNU C Library.
In the first step only the slower syscall is used for TLS
access. The uClibc-ng testsuite shows 79 errors, so their
is room for bugfixes and improvements.

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.

man feature_test_macros(7) specifies that _BSD_SOURCE and _SVID_SOURCE have
been deprecated in favor of _DEFAULT_SOURCE since libc 2.20. Specifying
either of the former is now equivalent to specifying just the latter. We add
this macro to conform to this standard, but do not add the compiler warning
to maintain full backwards compatibility with earlier version of glibc and
uclibc.

This is a second attempt to fix a compilation failure involving a
missing struct timespec definition in some situation. Previous attempt
was following commit but it had undesirable side effects and was
reverted:
657c4a9d6c fcntl.h: fix a missing `struct timespec` definition
A similar issue was identified and reported in glibc [1], and the fix
was to include the timespec definition if __USE_XOPEN2K8 was defined. To
minimize the possible impact of this new fix, it was decided to not
replace __USE_ATFILE by __USE_XOPEN2K8 as glibc did, but to add an
additional OR condition on __USE_XOPEN2K8.

This reverts commit 657c4a9d6c2e649d86307f46ce9d5e44192f6e7a.
This breaks a lot of package cross-compilation as lvm, ruby,
ipsec-tools. :(

The included RPC implementation is ipv4 only.
Other C library projects have either deprecated the internal
RPC implementation (GNU C Library) or never implemented such
functionality (musl C Library). The latest rpcbind release (0.2.4)
checks for libtirpc and does not allow to be build with uClibc-ng
RPC without patching. The common use case for RPC nowadays is to
use rpcbind together with nfs-utils to provide NFS server or client
support to a system.
The included RPC implementation does create issues with duplicate
symbol failures when statically compiling with RPC enabled.

If a source file is compiled with:
#define _XOPEN_SOURCE 700
#define _POSIX_C_SOURCE 200112L
Then including fcntl.h results in the following error:
In file included from fcntl.h:37:0,
from test.c:4:
sys/stat.h:371:54: error: array type has incomplete element type ‘struct timespec’
extern int futimens (int __fd, const struct timespec __times[2]) __THROW;
To fix that, we force the definition of struct timespec in fcntl.h when
__USE_XOPEN2K8 is defined. This mimics the behavior of glibc which
contains the following line in its io/fcntl.h header (included by
fcntlh.h):
#ifdef __USE_XOPEN2K8
# include <bits/types/struct_timespec.h>
#endif
This bug was spotted during the compilation of BoringSSL against uClibc.

This commit includes following features.
1. Support NPTL/TLS
2. Add libm function which is used to handle FP rounding and excpetions
(ex: fclrexcpt,fedisblxcpti,feenablxcpt... )
3. Add *context function for operating user context
(ex: setcontext,getcontext,makecontext... )
4. Change the return flow from signal handler
5. Cleanup of old code
The testsuite only has 2 errors, tst-cpuclock1 and tst-cputimer1,
which are related to timing accuracy. (math and locale tests are disabled)

Remove __UCLIBC_HAS_OBSTACK__ as it isn't very uptodate and
maintained part. It shouldn't be required for any software and
mostly shipped with stuff which use it. (f.e. binutils-gdb)
