The 'balanced' rule collects the locks that are taken and released
under the same condition, to prevent them from being reported as a
double lock. It runs on every file that contains a lock call.
To avoid this, collect the double-lock candidates first, so that
'balanced' runs only when one exists. The report then excludes what
'balanced' found.
Every double lock that can be reported is also a candidate, so the
same reports are made as before and the output does not change. A
report-mode run over every .c file in the tree produces identical
output.

Find double locks. False positives may occur when some paths cannot
occur at execution, due to the values of variables, and when there is
an intervening function call that releases the lock.
