The SysV ABI specifies that the symbol hash function should return only 32
bits of hash. Unfortunately due to an implementation bu and the fact that
the return type is unsigned long which is 64 bits in LP64, this can fail
in some cases: "\xff\x0f\x0f\x0f\x0f\x0f\x12". See:

Implement DT_GNU_HASH

DT_GNU_HASH serves the same purpose as DT_HASH, however it is a distinct
and faster apprach implemented and designed in the GNU toolchain in 2006.

DT_GNU_HASH is preferred whenever available.

Original GNU benchmarks claim 50% faster dynamic linking time.

Code based on FreeBSD and OpenBSD, both were based on DragonFlyBSD.

Implement and integrate GNU Hashing function

Define Elf_Hash struct that contains ELF/SYSV and GNU hash checksum.
Implement _rtld_gnu_hash() for DT_GNU_HASH.
Adapt existing code to compute all Elf_Hash types, instead of only
the ELF/SYSV one.
Rename _rtld_elf_hash() to _rtld_sysv_hash() to match the GNU toolchain
terminology.

_rtld_gnu_hash() uses Dan Bernstein's string hash function posted eons ago
on comp.lang.c.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.
Drop symbol number from default branch diagnostic, it isn't set at this
point and most likely not valid either.
Expand symnum, GCC's uninitialized used tracking is too imprecise.
Fix C&P bug. Deal with more MIPS hacks overriding def.
Add last_symnum, move up def and defobj.
Add back symnum, fix debug print.
Replace last use of r_type.
Fix indentation.

Add _dlauxinfo helper function to provide access to the ELF auxilary

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.

Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.

Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.

This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

Correct the lookup order of _rtld_symlook_default and make
_rtld_find_symdef use _rtld_symlook_default.

This reduces the code size and means that dlsym(RTLD_DEFAULT,...) has the
correct lookup order.

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.

As seen on tech-userlevel...

There are several optimizations here:

1) Objects on _rtld_list_main do not participate in the DAG structures
   at all.  This is okay because all symbols must be resolvable at
   link/load time, and _rtld_list_main is always searched first, so
   any references from those objects must necessarily be resolved to
   other objects on _rtld_list_main.

   (Making this work completely required setting obj->main a bit
   earlier; hence the RTLD_MAIN hack.)

2) Objects on _rtld_list_main are not put on _rtld_list_global,
   preventing an extra search.

3) A bit is used to keep track of whether an object is on
   _rtld_list_global, so we don't have to do a silly linear search.

4) A small attempt is made to prevent objects being put on the DAG
   lists multiple times (using a silly linear search).

The sum of this appears to be a ~10% (.3s) reduction in Mozilla's
startup time on my 800MHz box.

Also, make sure _rtld_objmain->path is always set, just to make the
debug output nicer.

Several small changes that shave 7-8% off the simple-exec-loop test:

* Rename _rtld_find_library() to _rtld_load_library().  It now calls
  _rtld_load_object() if necessary to actually load the object, rather
  than having the caller do it.  To do this, it also takes the `mode'
  argument that gets passed to _rtld_load_object().

* On a related note, remove _rtld_check_library(), and instead call
  _rtld_load_object() to instead try actually loading the object.  We
  save two extra namei's and a bunch of redundant work (almost
  literally the same code) this way.

* In _rtld_map_object(), mmap(2) the first page read-only, rather than
  read(2)ing it.

* In _rtld_symlook_obj(), compare the *second* character of the symbol
  name before calling strcmp().  (This first character is too
  frequently `_', and turns out to not be helpful, in libc.)

* Also in _rtld_symlook_obj(), remove the bogus STT_FUNC special case
  -- this also allows removing the `in_plt' argument to
  _rtld_symlook_list() and _rtld_symlook_obj().

Also:

* In _rtld_obj_from_addr(), rather than trying to look up `_end' in
  the each object, instead use obj->mapsize as the upper bound.

First cut at an ELF shared loader.  Originally from John Polstra's FreeBSD elf
kit, then hacked on by Matt Thomas <matt@3am-software.com>, then by me (to
make it work with new versions of the toolchain, etc.).  This runs, but it's
in serious need of cleaning and/or a fair bit of reworking.  See the README
file for more information, and a list of things to do.
