e48ce0cfe3 santad: Move signature fetching into SNTPolicyProcessor (#433)
This also removes an unnecessary hash, checks code signatures on non-MachO files (which is rare but possible) and fixes a rare crash in EndpointSecurityManager

6dc7387881 Add transitive whitelisting to Santa (#224)
Add transitive whitelisting.

Binaries may be identified with WHITELIST_COMPILER rules.  Any executable they output will then be marked locally with a transitive whitelist rule and allowed to run if the TransitiveWhitelistingEnabled config key is true.

This currently only prints the distribution of the non-root cache. In the near future I'll unify the caches again which stops this being a problem.

616fd9570f santa-driver: Split cache for root/non-root volume
Split the kernel-land cache into 2 separate caches, one for the root
volume and one for secondary volumes. When an unmount happens, clear
the non-root cache to ensure no overlap with filesystem IDs.

916c3c7a2a SNTXPCConnection: Re-add forced establishment of clients, better tests.
Previously SNTXPCConnection had two-way validation which, due to the method of
implementation, forced a client to connect to a server straight away. Once that
was removed, it meant invalidationHandlers aren't called if either end dies
before the connection is established.

This also puts back the acceptedHandler, which can be used to know when the
connection has finished being established (particularly useful on the server
side), updates the __weak stuff to use WEAKIFY/STRONGIFY macros (and now
actually switch them back to strong within each block) and make the
tests a lot better by using in-process anonymousListener's rather than
lots of mocking.

8eae9b7cb7 santad/SantaGUI: Refactor GUI<>santad connection logic and add queuing.
Instead of having santad create a listener for SantaGUI to connect to
and then reverse the client-server relationship, have SantaGUI create an
anonymous listener that it sends to santad using the control interface.

Also add a queue for notifications so that blocks that occur while
SantaGUI isn't running will show up once it starts.
