Add support for preinit, init and fini arrays. Some ABIs, in particular on ARM, do require working init arrays.
Traditional FreeBSD crt1 calls _init and _fini of the binary, instead of allowing runtime linker to arrange the calls. This was probably done to have the same crt code serve both statically and dynamically linked binaries. Since ABI mandates that first is called preinit array functions, then init, and then init array functions, the init have to be called from rtld now.
To provide binary compatibility to old FreeBSD crt1, which calls _init itself, rtld only calls intializers and finalizers for main binary if binary has a note indicating that new crt was used for linking. Add parsing of ELF notes to rtld, and cache p_osrel value since we parsed it anyway.
The patch is inspired by init_array support for DragonflyBSD, written by John Marino.

When loading dso without PT_GNU_STACK phdr, only call __pthread_map_stacks_exec() on architectures that allow executable stacks.

Now that the kernel defines CACHE_LINE_SIZE in machine/param.h, use that definition in the custom locking code for the run-time linker rather than local definitions.

Allow threading libraries to register their own locking implementation in case default one provided by rtld is not suitable.
Consolidate various identical MD lock implementation into a single file using appropriate machine/atomic.h.

Fix the handling of high PLT entries (> 32764) on sparc64. This requires additional arguments to reloc_jmpslot(), which is why MI code and MD code of other platforms had to be changed.

Update rtld for the "new" ia64 ABI. In the old toolchain, the DT_INIT and DT_FINI tags pointed to fptr records. In 2.11.2, it points to the actuall address of the function. On IA64 you cannot just take an address of a function, store it in a function pointer variable and call it.. the function pointers point to a fptr data block that has the target gp and address in it. This is absolutely necessary for using the in-tree binutils toolchain, but (unfortunately) will not work with old shared libraries. Save your old ld-elf.so.1 if you want to use old ones still. Do not mix-and-match.
This is a no-op change for i386 and alpha.

Add ia64 support. Various adjustments were made to existing targets to cope with a few interface changes required by the ia64. In particular, function pointers on ia64 need special treatment in rtld.
