ldso: fix x86_64 R_X86_64_TPOFF64 and R_X86_64_DTPOFF64 relocations

R_X86_64_TPOFF64 revealed by trivial testcase:
===================================================================
 #include <stdio.h>
 #include <errno.h>

int main() {
        void *a = &errno;

        printf("errno addr: %llx\n", a);

        return 0;
}
===================================================================

The addresses application got with R_X86_64_TPOFF64 was different than the once libc
internal __errno_location returned.

R_X86_64_DTPOFF64 testcase is even simpler than that:
===================================================================
 #include <stdio.h>
 #include <errno.h>
 #include <netdb.h>
 #undef h_errno

extern __thread int h_errno;

int main() {
        printf("h_errno addr: %llx\n", &h_errno);
        printf("__h_errno_location addr: %llx\n", __h_errno_location());
        return 0;
}
===================================================================

but needs to be linked with "-lpthread". This way we've got h_errno relocation via
R_X86_64_TPOFF64 in application and h_errno relocation via R_X86_64_DTPOFF64 in
libpthread which has its own __h_errno_location() (probably we can kill it later?).
And addresses were different again.

The problem is that both relocations resolve symbols in external modules and thus
should use symbol_addr instead of sym->st_value.

MIPS: restore INLINE_SYSCALL macro

The MIPS specific INLINE_SYSCALL macro has been renamed to
INLINE_SYSCALL_NCS with:

  763bbf9e9a27426c9be8322dca5ddf2cb4dbc464

  syscall: unify part 2: NCS variety

  Declare common NCS (non-constant syscall) variants and convert the
  existing ports over to this.

This change breaks system calls. The code generated with using of the
new macro does not obey the restartable syscall convention used by the
linux kernel. When it tries to restart the syscall the errno value is
not being replaced by the syscall number.

example:

nptl: fix libc internal, dynamically enabled locking

Final iteration to fix libc internal locking if libpthread is pulled
in by dlopen call (directly or indirectly).

We cannot really use the weak symbol trick for shared build, since
the symbols won't get refreshed if libpthread is pulled in dynamically.
In glibc, they have #ifdef SHARED magic to either use pthread_functions
table, or weaks. But as we shared object files with both builds, this
does not sounds good either.

The reintroduces the libc weaks.c, but uses them now only with static
build. For dynamic build, we still use the symbols with same name, but
provide weaks in forward.c so they end up dereferencing the
pthread_functions table indirectly if we are not linked to libpthread.
Mutex initialization is hard coded as inline, as it needs to happen even

This reverts most of commit 1610762362e651f86ca284ac59a1d7ec88034e4e.

Marking the symbols hidden is wrong, because libc accesses
the pthreads internal symbols for internal locking.

nptl: fix libc sigtimedwait

It seems that 57e8823548ad6e65d33b2153edeb18fb0edc20e6 removed completely
sigtimedwait symbol from libc which is wrong. I hope there is not too
many other things like this.

Apparently the libc_hidden_* macros actually make previously hidden
symbols visible globally (creates alias from __GI_* to *). This is
probably ancient confusion from times when gcc did not support
visibility attribute and hiding symbols was done using hacks like
this.

This also adds attribute_hidden to the internal __sigtimedwait for
nptl case.

nptl: fix libc sigaction signal checking

We should not check for SIGCANCEL in __libc_sigaction because nptl calls this
function to setup this signal. Nptl provides it's own override for sigaction
that checks that the user cannot override signals nptl uses internally.
Linuxthreads does not use SIGCANCEL at all so this affects nptl only.

nptl: turn pointer demangling off

Currently the stub calls would
demangle the pointer that is never mangled. Alternatively, we could sync
nptl/sysdeps/unix/sysv/linux/libc_pthread_init.c with new glibc version
that properly mangles the pointers, but that would need more validation
to make sure that all struct pthread_function readers do demangling.
uclibc currently does not do pointer mangling everywhere so it's more
consistent to just disable it here too.

nptl: mark symbols with libc forwarder hidden

Add attribute_hidden to all symbols having libc forwarder. This prevents
recursive self calls which would happen if libc is before libpthread in
linking order: the forwarder functions would call itself via the function
table, since the libpthread symbols would get overwritten with libc ones.
This has not been a problem in glibc since there these symbols are marked
hidden with linker version-script. Since we don't use one, we need to mark
these explicitly.
