Alfred Perlstein e722820434 Merge projects/enhanced_coredumps (r204346) into HEAD: 
Enhanced process coredump routines.

  This brings in the following features:
  1) Limit number of cores per process via the %I coredump formatter.
  Example:
    if corefilename is set to %N.%I.core AND num_cores = 3, then
    if a process "rpd" cores, then the corefile will be named
    "rpd.0.core", however if it cores again, then the kernel will
    generate "rpd.1.core" until we hit the limit of "num_cores".

    this is useful to get several corefiles, but also prevent filling
    the machine with corefiles.

  2) Encode machine hostname in core dump name via %H.

  3) Compress coredumps, useful for embedded platforms with limited space.
    A sysctl kern.compress_user_cores is made available if turned on.

    To enable compressed coredumps, the following config options need to be set:
    options COMPRESS_USER_CORES
    device zlib   # brings in the zlib requirements.
    device gzio   # brings in the kernel vnode gzip output module.

  4) Eventhandlers are fired to indicate coredumps in progress.

  5) The imgact sv_coredump routine has grown a flag to pass in more
  state, currently this is used only for passing a flag down to compress
  the coredump or not.

  Note that the gzio facility can be used for generic output of gzip'd
  streams via vnodes.
