Fix _mips_rtld_bind() to handle ELF filters.
MIPS does not use the common _rtld_bind() to handle runtime binding.
Instead, it uses a private _mips_rtld_bind(). Update _mips_rtld_bind()
to include the changes made to _rtld_bind() in r216695 and r218476 to
support upgrading the read-locked rtld_bind_lock to a write lock when
an object with a filter is encountered.
While here, add a 'where' variable to track the location of the fixup

Release laundered vnode pages to the head of the inactive queue.
The swap pager enqueues laundered pages near the head of the inactive queue
to avoid another trip through LRU before reclamation. This change adds
support for this behaviour to the vnode pager and makes use of it in UFS and
ext2fs. Some ioflag handling is consolidated into a common subroutine so
that this support can be easily extended to other filesystems which make use
of the buffer cache. No changes are needed for ZFS since its putpages
routine always undirties the pages before returning, and the laundry
thread requeues the pages appropriately in this case.

This little BSD licensed library has been kicking around for years.
It allows one to trivially convert an absolute path to a relative path
and the reverse. The test programs themselves are very useful in scripts
but the real use comes shortly with the -r and -a arguments to ln.
These are sometimes known as the --relative and --absolute flags and
can force a symlink to be relative when you only have an absolue path.
Another place these are sometimes used is to add -a and -r args to 'realpath'.
Incredibly useful in Makefiles.
I was going to just add the files in with 'ln' but a library makes more sense.
The test programs may come out in their own right some day for scripting.

[net80211] flesh out more IBSS 11n support
* Pepper comments around which describe what state(s) we're in when faking
up 11n nodes.
* By default don't fake it up as 11n until we properly negotiate the 11n
capabilities using probe request/response frames.
* Send a probe request with our HT information, as the 802.11-2012 spec
suggests.
* Reassociate with the driver if we've been promoted.
This is done because although learning a peer via beacons can learn 11n
state, learning peers via hearing probe frames and broadcast frames
does not. Thus, sometimes you end up with an 11n peer in the peer
table and sometimes you don't.
Note that the probe request/response exchange may not actually succeed.
Ideally we'd put the peer into some blocking state until we've exchanged
probe request/reponse to learn capabilities, or we timeout and just
stay non-11n.
This is more an experiment to get 11n IBSS nodes actually discovering
each other and be able to transmit. There are other issues that creep
up which I'll attempt to address in future commits.

For RTT calculations mid-session, we explicitly ignore ACKs with tsecr of 0 as
many borken middle-boxes tend to do that. But during 3whs, in syncache_expand(),
we don't do that which causes us to send a RST to such a client. Relax this

In particular:
- Do not use %ebx in the asm constraints on i386, since rtld is
compiled with -fPIC and gcc cannot handle GOT-base register reload
(clang and newer gcc can).
- Avoid direct use of [static N] construct in the function

Fix error reporting from wcstof()
When wcstof() skipped initial space and then parsing failed, it set
endptr to the first non-space character. Fix it to correctly report
failure by setting endptr to the beginning of the input string.
The fix is from theraven@, who fixed this bug in wcstod() and
wcstold() in r227753.
While I'm here:
Move assignments out of declarations in wcstod() and wcstold().
This is against my personal preference, but it is our agreed style(9).
Set endptr correctly on malloc() failure in all three functions.
Remove an incorrect comment: This is pointer arithmetic,
so the code was not actually making that assumption.
wcstold() advanced the wcp pointer beyond leading whitespace
and then reset it back to the beginning of the string.
Do not reset it. This seems to have no functional effect,
since strtold_l() also skips leading whitespace. I'm making
the change to keep this function consistent with wcstof() and
wcstod(), and because the C11 spec prescribes the use of iswspace()
to skip leading space.
