they become candidates for reuse. Without this fix, some of the
state from a thread structure's previous incarnation could interfere
with its new one. Specifically, a non-bound thread started as
"suspended" (see pthread_attr_setcreatesuspend_np()) might not get
scheduled at all when resumed, as the "active" flag would be set
spuriously.

compiles failing- usually due to some strange NFS drift which thinks
that the opt_ah.h in the compile directory is out of date wrt the
source it is copied from. When the copy is executed again, it fails
because the target is read-only. Oops. Modify the compile hooks

to determine which Elf Types are to be handled. Change the M4
templates to wrap an `#if __FreeBSD_version >= NNN'/`#endif' pair
around the generated code for each ELF data type, where `NNN' is
the OS version where the ELF type was added to the source tree.
This change allows cross-builds of old sources on newer FreeBSD
systems to work correctly.

elimination pass in the GCC 4.1 optimiser breaks the non-compliant behavior
on which FreeBSD relied. This change brings FreeBSD up to date by switching
trap frames to being explicitly passed by reference.

passed by value (trap frames) as if they were in fact being passed by
reference. For better or worse, this incorrect behaviour is no longer
present in gcc 4.1. In this patch I convert all trapframe arguments to
be explicitly pass by reference. I also remove vm86_initflags, pushing
the very little work that it actually does up into vm86_prepcall.

- The PCPU usage was to ensure that there were no faults on the stack while
the tte_hash_bucket lock was held - but this can be avoided by making sure
the address on the stack is already referenced.
- PCPU removal obviates the need for critical_{enter, exit}

after we perform the operations to delete the export,
call vfs_deleteopt() to delete the "export" mount option from
the linked list of mount options associated with that mount point.
This fixes one scenario:
- put a filesystem in /etc/exports to export it
- remove the filesystem from /etc/exports to delete the export and restart
mountd
- try to do a "mount -u -o ro" or "mount -u -o rw" on that filesystem
now that it is no longer exported.
