This makes it consistent with Samba, to ease transition.
Update unit test code to link to with tdb_wrap instead of including
db_wrap.c.
There are some potential whitespace fixes in this commit that have
been ignored. CTDB's lib/tdb_wrap will be deleted after the
transition to Samba's lib/tdb_wrap, so there's no point polishing it
too much.

This reverts commit 6578a97bd9.
This condition cannot happen since when recovery is triggered, all the
databases would get frozen and thawed in the order of priority. The only
other place where databases get frozen are for implementation of ctdb
wipedb/restoredb commands.

Database priority is a global property and all the nodes should have the
priority set for the databases. Just setting priority on one node can
lead to problems in the recovery as a database can be frozen at wrong
priority and then freezing database would not succeed.

reloadips really expects deleted IPs to be released before completing.
Otherwise the recovery daemon starts failing the local IP check. The
races that follow can cause a node to be banned.
To make the error handling simple, do the actual deletion in
release_ip_callback().
