Guard max lock setting with error check
We weren't checking for an error before setting the DB4 maxlocks
parameter, which could cause a NULL dereference in the error path.

Cleanup key array logic to make llvm scan-build happier
We can't have the size != 0 without keys != NULL, but the fact we
checked one at the start and the other later was confusing the static
checks from scan-build. Use size in both places; it keeps scan-build
happy and make the code a little easier to read.

Make keyd more robust in the face of socket errors
We were mostly ignoring errors back from reads or writes to the keyd
socket. Check that we've read/written as many bytes as we expect and
pull some of this out to common functions for sending keys/replies.

Make keyd internal functions static
Nothing else links to keyd.o, but these functions are internal so mark

Add error checking when trying to daemonize in keyd
We weren't checking the return from freopen, which causes warnings when

Check return value when writing PID to DB4 upgrade lock file
When writing our PID to the lock file for upgrading the DB4 version
we didn't check it was actually successful. This doesn't matter in
general (because it's the existence or not of the file we care about)
but catch it and error out appropriate anyway.

Fix issue with looking up keys by fingerprint via HKP interface
The index variable for the current parameter was being reused to parse
the fingerprint, resulting in attempting to free an unallocated piece of
memory and crashing. Use a different loop variable instead.

Add a reindex command to the onak tool
With the changes to the backends to store keys using the full fingerprints
it can be useful to force a key to be re-indexed and thus transitioned to
a fingerprint rather than 64 bit key id index. Ideally we'd want to be
able to do this across the entire backend, but that's a bit heavyweight for
a full keyserver so add the ability to do it for a single key to start with.

Check that signature data lengths do not exceed the available data
Some signatures have been witnessed on the keyserver network where the
hashed data lengths reported exceed the size of the overall packet. It
is assumed these are the results of some corruption somewhere, so if
they're detected don't try to parse any further (and drop them if we're
doing signature checking).

Don't end an existing transaction if trying to delete a non-existent key
The DB4 key deletion routine would always exit the current transaction
if the key wasn't found, even if it had been called by another function
which had entered the transaction. Only do so if the deletion routine
itself is what caused the transaction to be started.
