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@

Kernel and bootblocks still use the old 0L value until all the NULL abuses

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.

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.
