Michael Adam 3cb4bcd211 ctdb_client: fix race in starting concurrent transactions on a single node ...

There are two races in concurrent transactions on a single node.
One in starting a transaction, and one with committing (replaying).

This commit closes the first race by storing the pid in the
transaction-lock record and comparing the own pid against it
as a measure to prevent starting a second transaction when
a second node has come inbetween and changed the pid in the lock
record.
