riastradh | libc: Fix missing membar_consumer in dl_iterate_phdr.

Compute relocbase correctly for static PIE. AT_BASE is not usable in
this case.

Register dl_iterate_phdr in the libc's namespace.h
The NetBSD Standard C Library uses internally some of its functions with
a mangled symbol name, usually "_symbol". The internal functions shall not
use the global (public) symbols.
Stop using the public global name of dl_iterate_phdr in tls/tls.c:
__libc_static_tls_setup().
Follow the approach with other dlopen(3)-like functions with the
namespace.h in the dl_iterate_phdr() case. Use internally a weak symbol:
__dl_iterate_phdr instead of dl_iterate_phdr.

joerg | Implement __cxa_thread_atexit and __cxa_thread_atexit_impl. This
functions are used for destructors of thread_local objects.
If a pending destructor exists, prevent unloading of shared objects.
Introduce __dl_cxa_refcount interface for this purpose. When the last
reference is gone and the object has been dlclose'd before, the
unloading is finalized.
Ideally, __cxa_thread_atexit_impl wouldn't exist, but libstdc++ insists
on providing __cxa_thread_atexit as direct wrapper without further
patching.

christos | PR/45989: Martin Husemann: lint invocation does include -w only on i386
- turn lint -w for all the platforms after fixing the lint warnings.
- add _DIAGASSERTS() for casts that would assign values to types that
would not fit.
- change types, add casts
- change into ansii prototypes
- turn on _DIAGNOSTIC for libc (during current, to be eliminated for release
builds)

joerg | Add _dlauxinfo helper function to provide access to the ELF auxilary
vector. This can normally be found via __ps_strings, but libc is
initialised too early when linked dynamically and doesn't have access to
it yet, so provide an alternative mechanism via ld.elf_so.
Bump libc minor.

PR/45015: ld.elf_so: support ELF symbol versioning
Applied latest patch.

joerg | Avoid a dependency issue between pthread TLS by using simple atomic
initialisation, possibly running the initialisation loop more than once.
|

| 07-Mar-2011 |
joerg | Pass down ELF Auxillary Vectors for static NetBSD binaries too.
Rename __libc_init to _libc_init and call it explicitly from CSU code.
This enforces the constructor run order for newly linked programs.
Keep it as constructor with run-once semantic for binary compatibility.
Implement dl_iterate_phdr for statically linked programs.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

pooka | Add Solarisa-like dlinfo() interface to the ELF dynamic linker.
Implement RTLD_DI_LINKMAP which returns a pointer to the linkmap
chain at the given object. Other Solaris queries are currently
unimplemented.

thorpej | branches: 1.5.32; 1.5.40;
- Change the strong dlfcn names in libc to ___name, and make the __name
versions used by others in libc weak, so that we have:
name: weak
__name: weak
___name: strong
- Add __name strong aliases of the dlfcn names in ld.elf_so, so that we have:
name: strong
__name: strong
This allows ld.elf_so to self-resolve both the name and __name variants
of the dlfcn functions, the former being required for dlfcn support in
applications, the latter being required for dlfcn support in libc.
Fixes the problem described in:

skrll | branches: 1.4.2;
Resolve dlsym(3) and friends directly so that dlsym(RTLD_NEXT,...) works.
Previously dlsym resolved to the version in crt0.o or libc which would
mean that the caller's shared object couldn't be determined correctly
using __builtin_return_address(0).
Mainly from FreeBSD, but adapted by me. Benefits of this solutions are:
- backward comptibility maintained
- existing broken binaries are fixed with a new ld.elf_so
- __mainprog_obj can be removed from crt0.o
- we do the same thing as FreeBSD
Fixes PR 22067.
