Per Wayne Scott of Intel, the old sequence took 20cycles!!! on a P6.
Another nice side-benefit is that the kernel is about 3K smaller!!!

larger than the vfs layer can provide. We now automatically support
32K clusters if MSDOSFS is installed, and panic if a filesystem tries
to allocate a buffer larger than MAXBSIZE.
This commit is a result of some "prodding" by BDE.

Since locale reading code not resistent against stack overflowing or
similar intruder attacks, don't allow PATH_LOCALE env variable action
for s-bit programs (non-standard locale path setting)
number of mail messages sent per run was lowered from 2 to 1. Why? Well,
some numbers just give you the warm fuzzies, like zero and one. Zero isn't
much use here, so I picked my all time favourite, one.
strdup() it to prevent unsetenv() or setenv() effects. Check its length to
not allow user to overflow internal locale buffer. Move PATH_LOCALE
handling code into one place.
POSIX: make better stub for LC_MONETARY & LC_NUMERIC, now it check
locale directory existance instead of refusing all non-C non-POSIX
locales. POSIX treats empty locale env variable as unset variable
while our old code treats it as "C" locale, fix it. Implement previous locale
restoring, if locale setting fails. Old code assumes success if some
of LC_ALL subset is successed even other fails, POSIX treats it as
failure with previous locale restoring, fix it.
Remove unneccessary length checking in currentlocale()
ttymsg() insists on them not being there.
Also, since ttymsg() opens the tty "on demand", don't keep an fd open
ourselves. This would interfere with HUPCL etc.
This should close PR#2103 from <xaa@stack.nl>
as performed by the multicast kernel modifications. However, BSD
already had IPPROTO_ENCAP defined as 98 (RFC 1241 encapsulation).
This changes the use of IPPROTO_ENCAP to IPPROTO_IPIP, which is
the BSD name for IP proto 4.
