Fix stop update query
add a third query to start / stop

The queries have 'AND AcctStopTime IS NULL', which speeds up
the normal case substantially.  However, we can still have
the case where we get a delayed stop, or where the detail file
is being replayed multiple times.  We therefore want to be able
to insert the record where AcctStopTime is NOT NULL
If there's no Acct-Status-Type, ignore the packet

but still return OK
Fix typos
Add "split" functionality, so rlm_yubikey just works in more cases
Too many connections to a home server is INFO not WDEBUG
Doxygen
Replace ad-hoc code with RATE_LIMIT(...) macro

So that messages are limited to once per second
Replace EDEBUG and WDEBUG with ERROR and WARN
Add docs for REMARKER
Add better debugging messages when we fail to split an OTP string

api key is a secret too
Hide markers unless -Xx
Try not to leak so much memory on failure
that one too...
Remove unused variable
Remove extraneous quotes
Enable child thread for detail file reader.

Which is simpler and much faster.
Declare variable
