- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

MFV r248590,248594:
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.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

Merge r687-689,691,693-701,720 from libarchive.googlecode.com:
Translate getdate.y into C for portability. Make the get_date()
function easier to test as well:
* Have it accept a time_t "now" to use as a reference so that test
code can verify relative time specifications against known starting
points.
* Set up default date after parsing the string so that we
can use the specified timezone (if any) instead of the local
default. Otherwise, local DST makes it almost impossible to
reliably test time specifications such as "sunday UTC"

Merge r369 from libarchive.googlecode.com: Test -s option.

Test --strip-components and fix it to actually work. Jaakko did a
good job writing this test; it exercises a lot of subtle cases. The
trickiest one is that a hardlink to something that didn't get
extracted should not itself be extracted. In some sense, this is not
the desired behavior (we'd rather restore the file), but it's the best
you can do in a single-pass restore of a tar archive.

The test here should be extended to exercise cpio and newc formats as
well, since their hardlink models are different, which will lead to
different handling of some of these edge cases.

Test handling of restores relative to symlinks.
In particular:
* tar -x -P follows symlinks to existing dirs, but not without -P
* symlinks to files are always replaced
* broken symlinks are always replaced

Test for -q (aka --fast-read).
Fix the error uncovered by this test.

MFp4: bsdtar 2.5.4b

In addition to a number of bug fixes and minor changes:
* --numeric-owner (ignore user/group names on create and extract)
* -S (sparsify files on extraction)
* -s (regex filename substitutions)
* Use new libarchive 'linkify' to get correct hardlink handling for
both old and new cpio formats
* Rework 'copy' test to be insensitive to readdir() filename ordering

Most of the credit for this work goes to Joerg Sonnenberger, who
has been duplicating features from NetBSD's 'pax' program.

New bsdtar test harness. Still rather skimpy, but a lot easier
to run and maintain than the old scripts that used to be here.
