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.

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

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.
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.

Introduce a condition variable to avoid returning EBUSY when
the MAC policy list is busy during a load or unload attempt.
We assert no locks held during the cv wait, meaning we should
be fairly deadlock-safe. Because of the cv model and busy
count, it's possible for a cv waiter waiting for exclusive
access to the policy list to be starved by active and
long-lived access control/labeling events. For now, we
accept that as a necessary tradeoff.

Do a bit of cleanup. new_part() basically ignored the passed in size
