82185a52e2 Future proofing core file format
* The Haiku specific notes contain a structure size field, now.
* Change the type of the count and size fields in the Haiku specific
  notes to uint32 also for 64 bit ELF. The size field for a note is a
  uint32 anyway.

467fe4ca0c kernel: Add core dump facility
* Add function core_dump_write_core_file(). It writes a core file for
  the current thread's team. The file format is similar to that of
  other OSs (i.e. ELF with PT_LOAD segments and a PT_NOTE segment), but
  most of the notes are Haiku specific (infos for team, areas, images,
  threads). More data will probably need to be added.
* Add team flag TEAM_FLAG_DUMP_CORE, thread flag
  THREAD_FLAGS_TRAP_FOR_CORE_DUMP, and Team property coreDumpCondition,
  a condition variable available while a core dump is progress. A
  thread that finds its flag THREAD_FLAGS_TRAP_FOR_CORE_DUMP set before
  exiting the kernel to userland calls core_dump_trap_thread(), which
  blocks on the condition variable until the core dump has finished. We
  need the team's threads to stop so we can get their CPU state (and
  have a generally unchanging team state while writing the core file).
* Add user debugger message B_DEBUG_WRITE_CORE_FILE. It causes
  core_dump_write_core_file() to be called for the team.
* Dumping core as an immediate effect of a terminal signal has not been
  implemented yet, but that should be fairly straight forward.

e3616ca108 system: Provide elf.h to applications
Make a version of elf.h (assembled from the private header files
elf_common.h, elf32.h and elf64.h, and including Haiku's extensions for
C++) available to applications ported from UNIX.
