Replace <+... ...+> by ... when any.  <+... ...+> is slow, and in some
obscure cases involving backward jumps it doesn't force the unlock to
actually come after the end of the if.

This patch ensures that all semantic patches in the scripts/coccinelle
directory provide the report option.  Report messages that include line
numbers now have the line number preceded by "line" for easier subsequent
processing.

Find missing unlocks.  This semantic match considers the specific case
where the unlock is missing from an if branch, and there is a lock
before the if and an unlock after the if.  False positives are due to
cases where the if branch represents a case where the function is
supposed to exit with the lock held, or where there is some preceding
function call that releases the lock.
