Add a gfp_mask to audit_log_start() and audit_log(), to reduce the
amount of GFP_ATOMIC allocation -- most of it doesn't need to be 
GFP_ATOMIC. Also if the mask includes __GFP_WAIT, then wait up to
60 seconds for the auditd backlog to clear instead of immediately 
abandoning the message. 

The timeout should probably be made configurable, but for now it'll 
suffice that it only happens if auditd is actually running.

This patch should fix the avc_alloc_node() oom condition that Andrew
reported when no policy is loaded in SELinux.

Prior to this patch, when no policy was loaded, the SELinux "security
server" (policy engine) was only returning allowed decisions for the
requested permissions for each access check.  This caused the cache to
thrash when trying to use SELinux for real work with no policy loaded
(typically, the no policy loaded state is only for bootstrapping to the
point where we can load an initial policy).

This patch changes the SELinux security server to return the complete
allowed access vector at once, and then to reset the cache after the
initial policy load to flush the initial cache state created during
bootstrapping.

This patch adds more messages types to the audit subsystem so that audit 
analysis is quicker, intuitive, and more useful.

I forgot one type in the big patch. I need to add one for user space 
originating SE Linux avc messages. This is used by dbus and nscd.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
