Restore the fptr_t type of {init,fini}{,_array} that was removed when initial
support for indirect functions was added.  This fixes {init,fini}_array support
on hppa where each member of the array is (already) a plabel.

Discussed with joerg.

PT_GNU_RELRO segments are arranged such that their vaddr + memsz ends
on a linker common page size boundary.  However, if the common page size
used by the linker is less than the VM page size being used by the kernel,
this can end up in the middle of a VM page and when the region is write-
protected, this can cause objects in neighboring .data to get incorrectly
write-protected, resulting in a crash.

Avoid this situation by calculating the end of the RELRO region not by
rounding memsz up to the VM page size, but rather by adding vaddr + memsz
and then truncating to the VM page size.

Fixes PR toolchain/55043.

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.

Add basic support for indirect functions. It allows providing a public
function symbol with an implementation choosen at run time.
Refactor calls to functions by address in ld.elf_so to create temporary
function descriptors on the stack, if the address is not leaked outside.

Limitations:
- no support for initialising static storage with function pointers
- no support for unnamed resolver functions

Fixed handling of DT_SONAME:

	- add function to add name aliases for shared libraries loaded
	  XXX[1]: we don't add a name during load time, only when DT_SONAME
	  is present.
	- search already loaded objects in load_by_name for an already
	  loaded object that matches our name and return it.
	- add missing initialization and cleanup for obj->names
	  XXX[2]: should we make them SIMPLEQ?
	- Add XXX in rtld.c about getting the name of an object.

NB: This makes the jdk work again without resorting to a hack of putting
    the build path of libjvm.so into the run path (which is a security
    problem).

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.

Introduce a new type Elf_Symindx for use in decoding the symbol hash table
section and allow this type to be overridden.

The ELF specification says it should always be uint32_t (Elf_Word), but
alpha decided to be different (not sure why). Define Elf_Symindx to be
uint64_t on alpha.

Alpha no longer uses non-standard definitions of Elf64_Sword and
Elf64_Word.  Remove the ability to override these types.

Fixes ld.elf_so after Herculean effort from me and martin.

move the defines for RTLD_ARCH_SUBDIR into a sub-sub-makefile so we can
grab these values via reach-over more easily.
some fixes for PR#40170:
- set NATIVE=yes in the environment for genscripts.sh
- set LIB_PATH to /usr/lib/{sparc,i386} for those scripts
- set use_sysroot to "yes", to enable LIB_PATH to work in genscripts.sh
- get rid of building an a.out-happy ldd (but keep supporting a.out
  binaries for the ELF version.)
- convert a.out, elf32 and elf64 support into convience libraries and
  link them right ones in.  if elf_ldd() fails on 64 bit platforms,
  try elf32_ldd() before aout_ldd().
now ldd on 64 bit platforms works for 32 bit binaries, aka PR#40199,
and it seems that all the issues from README are gone too.
add some (uintptr_t) to some casts, so these compile with ELFSIZE=32
*and _LP64.  necessary for 32/64 bit combo ldd support.
- rework this a bunch to make it work inside /rescue/ldd.
- fix alpha build.

Figure out obj->pltrel(a) after the dynamic section is parsed, so the relative
order of DT_PLTREL and DT_JMPREL is irrelevant.  Removes the need for yet
another weird #ifdef.
Also, be slightly more careful with the rel(a)lim trimming.

If REL(A)SZ extends into .rel(a).plt, trim rel(a)lim.  This is actually due to
what is arguably a bug in BFD on some platforms (at least PPC and SPARC), but
I can't fix old binaries.

Catch up with type changes.  Also:

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.
