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.

If the loaded dso requires executable stack, as specified by PF_X bit of p_flags of PT_GNU_STACK phdr, but current stack protection does not permit execution, the __pthread_map_stacks_exec symbol is looked up and called. It should be implemented in libc or threading library and change the protection mode of all thread stacks to be executable.
Provide a private interface _rtld_get_stack_prot() to export the stack access mode as calculated by rtld.

Currently, when mapping an object, rtld reserves the whole address space for the mapping by the object' file with the protection and mode of the first loadable segment over the whole region. Then, it maps other segments at the appropriate addresses inside the region.
On amd64, due to default alignment of the segments being 1Gb, the subsequent segment mappings leave the holes in the region, that usually contain mapping of the object' file past eof. Such mappings prevent wiring of the address space, because the pages cannot be faulted in.
Change the way the mapping of the ELF objects is constructed, by first mapping PROT_NONE anonymous memory over the whole range, and then mapping the segments of the object over it. Take advantage of this new order and allocate .bss by changing the protection of the range instead of remapping.
Note that we cannot simply keep the holes between segments, because other mappings may be made there. Among other issues, when the dso is unloaded, rtld unmaps the whole region, deleting unrelated mappings.
The kernel ELF image activator does put the holes between segments, but this is not critical for now because kernel loads only executable image and interpreter, both cannot be unloaded. This will be fixed later, if needed.

Implement the dynamic string token substitution in the rpath and soneeded pathes. The $ORIGIN, $OSNAME, $OSREL and $PLATFORM tokens are supported. Enabling the substitution requires DF_ORIGIN flag in DT_FLAGS or DF_1_ORIGIN if DF_FLAGS_1, that may be set with -z origin gnu ld flag. Translation is unconditionally disabled for setuid/setgid processes.
The $ORIGIN translation relies on the AT_EXECPATH auxinfo supplied by kernel.

Change the way ELF coredumps are handled. Instead of unconditionally skipping read-only pages, which can result in valuable non-text-related data not getting dumped, the ELF loader and the dynamic loader now mark read-only text pages NOCORE and the coredump code only checks (primarily) for complete inaccessibility of the page or NOCORE being set.
Certain applications which map large amounts of read-only data will produce much larger cores. A new sysctl has been added, debug.elf_legacy_coredump, which will revert to the old behavior.
This commit represents collaborative work by all parties involved. The PR contains a program demonstrating the problem.

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.

Revamp the symbol lookup algorithm to cope better with objects loaded separately by dlopen that have global symbols with identical names. Viewing each dlopened object as a DAG which is linked by its DT_NEEDED entries in the dynamic table, the search order is as follows:
* If the referencing object was linked with -Bsymbolic, search it internally. * Search all dlopened DAGs containing the referencing object. * Search all objects loaded at program start up. * Search all objects which were dlopened() using the RTLD_GLOBAL flag (which is now supported too).
The search terminates as soon as a strong definition is found. Lacking that, the first weak definition is used.
These rules match those of Solaris, as best I could determine them from its vague manual pages and the results of experiments I performed.
