[systemd-devel] [PATCH, REVIEW] Added unit enabled-context cache to improve performance w/ many units.

[Ken Sedgwick]

The attached patch adds an EnabledContext cache so systems with 1000s of
units do not suffer
O(N^2) performance when determining unit state.  The test-enabled unit test
(added to master under other patch)
is used to confirm that the returned states are the same as the current
master.

Please review.

Many thanks in advance,

Ken
