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.

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'.

This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
This creates a new version of the FreeBSD core file note generation
logic in the new target-dependent file "fbsd-tdep.c". The new version
is mostly copied from "fbsd-nat.c", but uses the iterator instead of
regset_from_core_section and defines fbsd_make_corefile_notes as a
gdbarch method instead of a target method.
Consecutive architecture-dependent changes exploit the new version,
migrating away from the target method. When all FreeBSD targets are
changed, the target method can go away.
gdb/ChangeLog:
* fbsd-tdep.c: New file.
* fbsd-tdep.h: New file.
* Makefile.in (ALL_TARGET_OBS): Add fbsd-tdep.o.
(HFILES_NO_SRCDIR): Add fbsd-tdep.h.
(ALLDEPFILES): Add fbsd-tdep.c.
