There are no contexts any more. Rename the log message IDs not to
contain them.

Since creating new file is suspicious, the administrator may have
misspelled some file name. The message explains the problem and shows
the file name as well.

Also, removed a duplicate message, created a new instance for it.

- add zone and file names to masterload errors
- catch masterload error and log it
- don't quit auth completely on a single zone load failure

At least for some logging. This eliminates having more real parameters
than placeholders for the used messages. Other occurrences of the
function are preserved, as the corresponding messages have full set of
placeholders.

The DATASRC_DATABASE_FINDNSEC3_COVER logging message was missing a
placeholder. Added.

One missing placeholder and one explanation in the text.

it didn't seem correct to say "it's not allowed on the wire".  this
restriction is more about the definition of the RRset concept, rather than
what we'd see in the wire.  also added a reference to the relevant RFC (2181).

also, in sqlite3 accessor and the old data source API, check both the
major and minor versions, log any mismatches, and throw if major doesn't
match.  right now there's no test for it, which is bad, but this seems to
be best way forward from the given patch.

using debug level of 40 for now.

This is for ticket #1102.

Also clarify the log description.

No changelog entry.

Discussed some on jabber.

for the positive case to a separate method and used it directly from find()
and findWildcardMatch().  Moved detailed comments of findWildcardMatch to
the head of its definition so that the function body will be physically
concise.

Added utility to put messages in a message file into alphabetical
order and, for ease of further editing, the data source message file
in alphabetical order.

ones for each subcase of find().

As the concerns there seem to be false ones.

catch exception in rollback explicitly.  added a test case for that.

When we iterate and find out that there are RRs in an RRset with
different TTL, we go for the lowest of them instead of throwing and give
a warning.

added some log messages.  to make the log/exception messages useful,
also added an RRClass parameter to the Client constructor.
