  -----------
  Add "process metadata" Mach-O LC_NOTE for corefiles

Add a new LC_NOTE for Mach-O corefiles, "proces metadata", which is a
JSON string.  Currently there may be a `threads` key in the JSON,
and if `threads` is present, it is an array with the same number of
elements as there are LC_THREADs in the corefile.  This patch adds
support for a `thread_id` key-value for each `thread` entry, to
supply a thread ID for that LC_THREAD.
