If RTLD_NODELETE is passed to dlopen() rather than set on shared
library itself, flag propagation to rtld_flags is missed.

The required test for the internal NPTL used signals isn't
implemented.

Invoke pthread_atfork handler cleanup when removing the associated DSO...
If a program loads a DSO (dlopen) that sets up a pthread_atfork handler(s), and
then subsequently closes the DSO, the handler(s) are left in place. If fork()
is subsequently called, the handlers are invoked even though the DSO has been
removed causing crashes or unpredictable code execution. This is because the
code in __cxa_finalize(atexit.c)to invoke the unregister_atfork() routine is
ifdef'd out with the comment that it hasn't been "looked into this yet...".

Although gethostent() is obsoleted, there is no reason to keep it broken.
Fix two problems:
* commit f65e66078b "resolver: switch to config parser" leave an extra break
statement in case of GETHOSTENT in __read_etc_hosts_r. In result,
output buffer wasn't initialized at all.
* gethostent static buffer has insufficient size to store aliases,
so __read_etc_hosts_r always returns ERANGE. Restore ALIAS_DIM define.
Add test-case.

Both architectures are more or less deprecated.
No Linux upstream support, no gcc support for uClinux.

Argp is an advanced support for parsing unix-style argument vectors.
In addition to the common getopt interface, it provides automatic
response
to `--help' and `--version' options and use of custom parser in
conjunction
with argp native option parser, among others.
Argp support is required by elfutils package and prelink.
In uClibc argp functionalities has been moved from C library to
libuargp.so
Further the libc.so linker script contains an AS_NEEDED entry so that
it doesn't need to link libuargp.so explicitely.
Disable argp test if feature disabled.

Commit e3c3bf2b58 introduce use of pselect6, but has following disadvantages:
* Use of userspace types in args67 structure - it breaks, for example,
configs when 32-bit uClibc-ng compiled against 64-bit kernel. Syscall
will always return EINVAL. We must use __kernel_* types and
__SYSCALL_SIGSET_T_SIZE.
* It have excess checks for NSEC_PER_SEC. Original code from select()
implementation has struct timeval => struct timespec conversion,
kernel select() syscall implementation do the same.
But none of libc versions (glibc, eglibc, musl) I know, perform similar
checks for pselect() - there is no structure fields conversions,
just struct timespec through all the calls.
To have such checks in uClibc-ng we need one example, at least.
* It is possible to avoid extra userspace reads from kernel code if
sigmask == NULL. I suggest to do it, for a few bytes cost.
* Commit didn't add test case to testsuite.

Using non-generic ulps file reduces failure counts for
math tests. Generated with nsim emulator running
test-{double,idouble,float,ifloat} -u and
gen-libm-test.pl on the build host.

When cross-compiling on other Unix systems like
FreeBSD 10.x, perl is not in /usr/bin. Use env
to find the perl interpreter and use no fixed path
when executing via make.

Reduce the initial buffer size for open_memstream (used by vasprintf),
as most strings are usually smaller than that.
Realloc the buffer after finishing the string to further reduce size.

Most changes are mechanical replacement of 'retw' instruction with
'abi_ret' macro, defined to 'retw' or 'ret' according to ABI.
Assembly code that makes calls is duplicated for call0 ABI with changed
register numbers for parameters/return value and call instruction.
'entry' instructions are replaced with 'abi_entry' macro.
More interesting changes:
- non-leaf assembly functions (e.g. _dl_tlsdesc_dynamic,
_dl_linux_resolve, SYSCALL_ERROR_HANDLER, PSEUDO) now need to preserve
registers around intermediate calls they make, use temporary stack
frame for that;
- setjmp/longjmp only need to save and restore return address, stack
pointer and callee-saved registers in the jmpbuf;
- __clone and syscall functions had hardcoded offsets to parameter
passed on stack, on call0 ABI they don't need stack frame, so the
offset is different. Replace these offsets with FRAMESIZE macro.

TLS_LD should use linker-provided symbol _TLS_MODULE_BASE_ instead of
symbol it resolves to get thread pointer, otherwise linker relaxation
doesn't work correctly, adding extra offset to thread-local variable
address.
This fixes most of tls/tst-tls* tests.

When attempting to build uClibc under buildroot, including building the
tests, the silly tests don't currently compile, a result of attempting
to build using a compiler that does not yet have an installed version of
uClibc available. The error is a missing header file, specifically
atomic.h.
Taking inspiration from the nptl tests, I have extended the EXTRA_CFLAGS
variable to add the required include paths. The tests can now be built
under buildroot.

The current code implements the 'm' modifier only for 's'
conversions and would cause a segfault if it was used for 'c'
or '[' conversions. This patch extends the code to cover these
cases too.
The original version could write scanned data outside the passed buffer
because index i used in the '[' conversion handling block was clobbered.

As reported by Alexey Brodkin <Alexey.Brodkin@synopsys.com>
these tests do not fail anymore. After upgrading binutils/gcc
tests compile fine.
