cmdlib: Stop using proc.Log*

The Log* functions are re-exported through the LU. Inline use of string
formatting (“%”) was converted to additional arguments to Log* (unlike
“feedback_fn”, these functions support it). Some punctuation has been
removed from messages, as well as some small re-wordings....

A new method is added to check whether the LockSet-internal lock is
held. This is the case after LockSet.acquire was called with

Unit tests are updated, including one where the list of names must be...

mcpu: Start locking at correct level

Commit 8716b1d added a new lock level, LEVEL_NODE_ALLOC. It is ahead of
LEVEL_INSTANCE. The latter was hardcoded in mcpu to be locked right
after the BGL, effectively ignoring LEVEL_NODE_ALLOC.

Add new lock level for node allocations

The new lock is similar to the BGL in the sense that it has its own
level and there is only one. It is called “node allocation lock”.
Logical units will use it to synchronize with instance creations, which
in turn will start using opportunistic locks on nodes....
