(the two may be different (ie, build vs. runtime))
Allow ldscript's SEARCH_DIR do be rooted somewhere other than `/'.
(in this case at TOOLS_PREFIX)
These changes are most helpful during `make buildworld' so that the shared
libs built in the middle of `make buildworld' are used vs. the ones in
/usr/lib on the build machine.

without being reclaimed. This bug was introduced in revision 1.95
dealing with filenames placed in newly allocated directory blocks,
thus is not present in 4.X systems. The bug is triggered when a
new entry is made in a directory after the data block containing
the original new entry has been written, but before the inode
that references the data block has been written.

to fix their code.
ata stuff:
Change name of ar_attach to not colide with existing ar_attach in if_ar.c.
usb stuff:
Create a dummy function to satisfy a call to it when in DEBUG mode.
now it is fixed. This should get us a working keyserv again, since
it depends on local transport for key exchange.
Since we do not have any KEYFILE name hardcoded anymore, set the
umask that way that the keyserver socket can be created with with
the appropriate permissions.
Re-add the accidently removed signal(SIGPIPE, SIG_IGN); to the code
which makes sense to avoid SIGPIPE when a disconnect on rpc socket
occurs.

The changes from GCC 2.95.3 to 3.1 are large and it is hard to figure
out how to apply our changes. Once BDE can properly test GCC 3.1 he'll
add back in our changes.
- Create a private list of active pmaps rather than abusing the list of all
processes when we need to look up pmaps. The process list needs a sx lock
and we can't be getting sx locks in the middle of cpu_switch()
(pmap_activate() can call pmap_get_asn() from cpu_switch()). Instead, we
protect the list with a spinlock. This also means the list is shorter
since a pmap can be used by more than one process and we could (at least
in thoery) dink with pmap's more than once, but now we only touch each
pmap once when we have to update all of them.
- Wrap pmap_activate()'s code to get a new ASN in an explicit critical section
so that when it is called while doing an exec() we can't get preempted.
- Replace splhigh() in pmap_growkernel() with a critical section to prevent
preemption while we are adjusting the kernel page tables.
- Fixes abuse of PCPU_GET(), which doesn't return an L-value.
- Also adds some slight cleanups to the ASN handling by adding some macros
instead of magic numbers in relation to the ASN and ASN generations.
