Previously corrupt note namesz or descsz (perhaps caused by readelf's
current lack of endian support for notes) resulted in a crash. Check
that namesz and descsz do not extend beyond the end of the buffer before
trying to access name and desc data.

Reserve WXNEEDED ELF feature control flag

This will be used to tag binaries that require W+X mappings, in advance
of the ability to prevent W^X in mmap/mprotect.

There is still some discussion about the flag's name, but the ABI won't
change even if the name does (as kib pointed out in the review).

readelf: Close input files when done with them.

The low fd limit used by poudriere exposed an odd failure mode in
cap_fileargs (used by readelf as of r350516). In particular, when
the limit was hit, both the main process and casper service would
block on their shared socket, waiting forever for the other to send a

Teach readelf about some OpenBSD ELF program headers

- Add constants for OpenBSD wxneeded, bootdata and randomize to the
FreeBSD elf_common.h file. This is the file that gets used by the
elftoolchain library.
- Update readelf and elfdump utilities to decode these program headers
if they are encountered.

Note: FreeBSD has it's own version of elfdump(1), which will be updated
in a subsequent commit. I am adding it here anyway because this diff is
going to be submitted upstream.
