Update libarchive to 3.1.2

Some of new features:
- support for lrzip and grzip compression
- support for writing tar v7 format
- b64encode and uuencode filters
- support for __MACOSX directory in Zip archives
- support for lzop compresion (external utility)

Update libarchive to 3.0.4

Update libarchive to 3.0.3

Some of new features:
- New readers: RAR, LHA/LZH, CAB reader, 7-Zip
- New writers: ISO9660, XAR
- Improvements to many formats, especially including ISO9660 and Zip
- Stackable write filters to write, e.g., tar.gz.uu in a single pass
- Exploit seekable input; new "seekable" Zip reader can exploit the Zip
Central Directory when it's available; the old "streamable" Zip reader
is still fully supported for cases where seeking is not possible.

Merge FreeBSD changes from lib/libarchive to contrib/libarchive:

r204111 (uqs):
Fix common misspelling of hierarchy

r208027 (uqs):
mdoc: move CAVEATS, BUGS and SECURITY CONSIDERATIONS sections to the
bottom of the manpages and order them consistently.

GNU groff doesn't care about the ordering, and doesn't even mention
CAVEATS and SECURITY CONSIDERATIONS as common sections and where to put
them.

r208291 (uqs):
mdoc: consistently spell our email addresses <foo@FreeBSD.org>

r209031 (uqs):
mdoc nitpicking: the title argument shall be uppercase

r214822 (kientzle):
Clarify the naming: Methods that free an object should
be called "free". Retain the old "finish" names to preserve
source compatibility for now.

r214905 (kientzle):
If the Zip reader doesn't see a PK signature block
because there's inter-entry garbage, just scan forward
to find the next one. This allows us to handle a lot
of Zip archives that have been modified in-place.

Thanks to: Gleb Kurtsou for sending me a sample archive

r216258 (kientzle):
Don't write data into an empty "file."

In particular, this check avoids a warning when
extracting directory entries from certain GNU tar
archives that store directory contents.

r225525 (kientzle):
Fix cpio on ARM.
