Unbreak kernel build.

Remove a bunch of #include "opt_pci.h".
Remove opt_pci.h from SRCS.
Use `krb5_get_err_text' instead of `error_message' so that instead of
e.g.

   Unknown error: -1765328378

we get

   Client not found in Kerberos database

Another way to accomplish this would have been to leave
`error_message' alone, but to explicitly load the Kerberos com_err
error tables.  However, I don't really like the idea of a PAM module
dorking with global tables.

Remove opt_pci.h from SRCS, it doesn't exist anymore.
The pam_krb5 module stored a reference to a krb5_ccache structure as
PAM module state (created in pam_sm_authenticate and referenced later
in pam_sm_setcred and pam_sm_acct_mgmt).  However, the krb5_ccache
structure shares some data members with the krb5_context structure
that was used in its creation.  Since a new krb5_context is created
and destroyed at each PAM entry point, this inevitably caused the
krb5_ccache structure to reference free'd memory.

Now instead of storing a pointer to the krb5_ccache structure,
we store the name of the cache (e.g. `MEMORY:0x123CACHE') in
pam_sm_authenticate, and resolve the name in the other entry points.

This bug was uncovered by phkmalloc's free'd memory scrubbing.

Remove a commented out #include "opt_pci.h", it doesn't
exist anymore.
Use a jump table (a la Solaris) for pthread routines with default
entries in the table being stubs.  While I'm here, add macros to
auto-generate the stubs.  A conforming threads library can override
the stub routines by filling in the jump table.

Add some entries to namespace.h and sync un-namespace.h to it.
Also add a comment to remind folks to update un-namespace.h
when changing namespace.h.
At initialization, override the pthread stub routines in libc
by filling in the jump table.

Convert uses of pthread routines within libc_r to use the internal
versions (_pthread_foo instead of pthread_foo).

Remove a couple of globals from application namespace.
New release notes:  SA-02:40, SA-02:41, SA-02:42.
- Fix some minor grammar and spelling nits.
- Massage the wording in a few places.
- Put .Nm on lines by itself so it renders correctly.

in various revisions of vm/vm_map.c between 1.148 and 1.153.
Remove getopt and strtol dependencies, reducing size of static exe.

Try to reword things a bit more to make it clearer.

Recognize the Serverworks CIOB30 host to pci bridge.
Argh, change declaration of two-dimensional array so that it actually
builds.
When parsing the CIS, if a BAR tuple is encountered, enable the corresponding
bit in the PCI command register for the device.  Otherwise, device drivers
that look at this register to see which types of BARs are usable will think
that none of them are.
This allows my Adaptec 1480A cardbus card to finally work.

Back out previous commit since there is controversy about changing so much
in sleep including duping strtol(3).  Code changes also increased
dynamic size of sleep(1).
Minimal take on previous commit -- remove getopt and printf.  Static size
is reduced by 40k, dynamic by a few bytes.
Functional changes:
* "sleep -- arg" now returns usage() instead of ignoring the --
* "sleep -1" now returns immediately instead of returning usage()
