Add support for 'info proc files' on FreeBSD core dumps.
Walk the list of struct kinfo_file objects in the
NT_FREEBSD_PROCSTAT_FILES core dump note outputting a description of
each open file descriptor. For sockets, the local and remote socket
addresses are displayed in place of the file name field. For UNIX
local domain sockets, only a single address is displayed since most
UNIX sockets only have one valid address and printing both pathnames
could be quite long. The output format was somewhat inspired by the
output of the "procstat -f" command on FreeBSD, but with a few less
details and some fields were condensed.

Support 'info proc' for FreeBSD process core dumps.
- Command line arguments are obtained from the pr_psargs[] array
saved in the NT_PRPSINFO note.
- The 'cwd' and 'exe' values are obtained from the per-process file
descriptor table stored in the NT_PROCSTAT_FILES core note.
- 'mappings' is implemented by walking the array of VM map entries
stored in the NT_PROCSTAT_VMMAP core note.
- 'status' output is generated by outputting fields from
the first structure stored in the NT_PROCSTAT_PROC core note.
- 'stat' is aliased to 'status'.
