kernel page table page to have a legitimate pindex to support superpage
promotion on kernel memory.
Correct a nearby style error: Pointers should be compared to NULL.

pages' flags and its population count can be inconsistent. That could
result in a page being freed twice.

* prototypes for optarg/optind on platforms that don't already have them
* Disambiguate version number macros
* Remove unnecessary PACKAGE_NAME macro
* Hook for forthcoming bsdtar test suite
* Sync version number up with the portable distribution

doesn't; it proved useful in bsdcpio as well, so I pushed it down
into libarchive.)
exercises and verifies the libarchive APIs:
* Improved error reporting; hexdumps are now provided for
many file/memory content differences.
* Overall status more clearly counts "tests" and "assertions"
* Reference files can now be stored on disk instead of having
to be compiled into the test program itself. A couple of
tests have been converted to this more natural structure.
* Several memory leaks corrected so that leaks within libarchive
itself can be more easily detected and diagnosed.
* New test: GNU tar compatibility
* New test: Zip compatibility
* New test: Zero-byte writes to a compressed archive entry
* New test: archive_entry_strmode() format verification
* New test: mtree reader
* New test: write/read of large (2G - 1TB) entries to tar archives
(thanks to recent performance work, this test only requires a few seconds)
* New test: detailed format verification of cpio odc and newc writers
* Many minor additions/improvements to existing tests as well.

I also need to reconcile a few issues between this

mtree utility.

probably the right thing to do a while ago but xorg has progressed
to the point that for novice users (who are the ones expected to think
installing X11 during an install...) it's best to just install the
whole x11/xorg metaport for them. This removes the X11 sub-menus
and sets it up so you just select whether or not you want X11. While
here garbage collect an X11 configuration menu I missed removing when
I removed support for attempting xorg configuration from inside sysinstall
a while ago.

of two compares against 0. The negative effect of cache flushing
is probably more than the gain by not doing the two compares (the
value is almost certainly in register or at worst, cache).
Note that the uses of m_freem() are in error cases and m_freem()
handles NULL anyhow. So fast-path really isn't changed much at all.
feature is represented by a node in the new 'kern.features' sysctl node.
A feature is present if the corresponding node is present and evaluates to
true.
A FEATURE() wrapper macro is added which takes the sysctl node name and
a description of the feature as the sole arguments and creates a read-only
sysctl node with a value of 1.

Clean up DSS-related locking and protect all pertinent variables with
dss_mtx (remove dss_chunks_mtx). This fixes race conditions that could
cause chunk leaks.
Reported by: [1] kris
This is a long-standing bug, but until recent changes it was difficult
to trigger, and even then its impact was non-catastrophic, with the
exception of revision 1.157.
Optimize chunk_alloc_mmap() to avoid the need for unmapping pages in the
common case. Thanks go to Kris Kennaway for a patch that inspired this
change.
Do not maintain a record of previously mmap'ed chunk address ranges.
The original intent was to avoid the extra system call overhead in
chunk_alloc_mmap(), which is no longer a concern. This also allows some
simplifications for the tree of unused DSS chunks.
Introduce huge_mtx and dss_chunks_mtx to replace chunks_mtx. There was
no compelling reason to use the same mutex for these disjoint purposes.
Avoid memset() for huge allocations when possible.
Maintain two trees instead of one for tracking unused DSS address
ranges. This allows scalable allocation of multi-chunk huge objects in
the DSS. Previously, multi-chunk huge allocation requests failed if the
DSS could not be extended.
