largest size for a buffer in the buffer cache. This patch
defines a new constant MAXBCACHEBUF, which is the largest
size for a buffer in the buffer cache. Having a separate
constant allows MAXBCACHEBUF to be set larger than MAXBSIZE
on a per-architecture basis, so that NFS can do larger read/writes
for these architectures. It modifies sys/param.h so that BKVASIZE
can also be set on a per-architecture basis.
A couple of cases where NFS used MAXBSIZE instead of NFS_MAXBSIZE
is fixed as well.

Attempt to connect to alternate addresses if the connect doesn't
succeed in 180ms, and cut wait time between connection attempts
in half for each additional, if no connection was established.
Take the first connection to succeed and close the others.
This makes whois more responsive when e.g. IPv6 service took long
time or fail to respond.

trying to build a cluster. The limit is tunable using the sysctl
vfs.ffs.maxclustersearch. The current limit is 10 cylinder groups
per block allocation. It was previously limited to the number of
cylinder groups in the filesystem per block allocation. When there
were no clusters of the needed size left, it repeatedly searched
the whole filesystem for a non-existent cluster on every block
allocation. The result was very slow filesystem allocation with
100% CPU utilization. The old behavior can be had by setting
vfs.ffs.maxclustersearch to a huge number (1,000,000).
This change affects only the layout policy routines so is not able
to interfere with the integrity of the filesystem.

gcc 4.9 added support for new alignment attribute alloc_align:
The alloc_align attribute is used to tell the compiler that the function
return value points to memory, where the returned pointer minimum
alignment is given by one of the functions parameters. GCC uses this
information to improve pointer alignment analysis.
This attribute is not (yet) available on clang.
vt_is_cursor_in_area needs to return true if any part of the mouse

Fix a missing .h and change the recommended include for the POSIX2008 functions from xlocale.h to locale.h. Including xlocale.h is for legacy / Darwin compatibility so should not be encouraged.
It would previously call into some unfinished Solaris compatibility code and
return without actually calling panic(9). The compatibility code is
unneeded, however, so just remove it and have dtrace_panic() call vpanic(9)
directly.

- Board serial and revision;
