funopen(): change seekfn argument to use off_t, not fpos_t
On BSD, fpos_t is typedef'd to off_t but some systems use a struct.
This means fpos_t is not a portable function argument or return value.
Both FreeBSD and the Linux libbsd funopen() have switched to off_t
for this--we should too. From Joe Nelson. OK deraadt@

Define NULL as a void * instead of a long integer, as required by Single Unix.
Kernel and bootblocks still use the old 0L value until all the NULL abuses
in the code are fixed.

Fix the handle locking in stdio to use flockfile/funlockfile
internally when and where required. Macros in <stdio.h> are updated
to automatically call the underlying functions when the process is
threaded to obtain the necessary locking. A private mutex is added
to protect __sglue, the internal list of FILE handles, and another
to protect the one-time initialization. Some routines in libc that
use getc() change to use getc_unlocked() as they're either protected
by their own lock or aren't thread-safe routines anyway.

There's a major libc bump coming that is going to cover this as well...

Change internals of FILE: reuse the unget buffer field to access an
extended attribute data structure (pimpl idiom). Idea taken from citrus.
Much discussion with deraadt@, otto@, millert@...

This is the least disruptive way to extend FILE, since its size can't really
change without this being a flag day. So the size doesn't change.

Actual additions to the structure will come in separate steps, since this
change is nasty enough on its own.

Tests by otto@ and others, careful reading of code by otto@ and millert@.

This is definitely a major bump, and has been checked to not impact a
full ports build.

Don't define EOF In ctype.h, some 3rd party code checks whether or

Make P_tmpdir point to /tmp/ not /var/tmp
Really, there should be a way to make configurable by the admin

Use an _BSD_FOO_T_ type declaration for off_t in machine/ansi.h to allow
off_t to be visible in stdio.h even in strict ansi mode. This is needed
for ftello()/fseeko() and it allows us to remove the horrible fpos_t hack.

Add fseeko() and ftello() -- versions of fseek() and ftell() that use off_t.
Also make fsetpos() and fgetpos() use fseeko() and ftello() respectively
since fpos_t is actually a 64bit type.
