Reapply MXS-504 changes subsequent to optimisation changes. Merge SSL processing into non-SSL processing so far as possible, correct usage of OpenSSL, simplify where possible.

Switch bitmask_clear to be locking and offer bitmask_clear_without_spinlock for non-locking version, in response to review comments. Revert poll.c to use bitmask_clear (with locking) and amend dcb.c to use the non-locking version and to take advantage of the return of an indication of whether the whole bitmask is then clearn.

Various optimisations of bitmask processing. External change is that bitmask_clear() does not apply a spinlock, so must be called with exclusive access to the bitmask. This affects the call in shutdown processing in poll management. The call from DCB processing is safe because zombie processing has exclusive access to DCBs.

Allow hangup event also when EPOLLRDHUP is not available.
...
When generating a fake hangup event, EPOLLRDHUP is used if available,
otherwise EPOLLHUP. process_pollq(int) does the same thing both in the
case of EPOLLRDHUP and EPOLLHUP, so it seems this should work.

Remove all traces of logfile_t
...
The earlier log file based approach for enabling and disabling
messages has now been completely replaced with the syslog priority
based approach.
Similarly as with log files before it is now possible to enable
and disable a log priority for a particular session, even though
it apparently has not been used much.
The local test-programs of the logging has got minimal attention
only to make them compile. They should get an overhaul as they did
not work before either.

Reset sessionid upon exit.

Session info always copied to tls
...
Maxadmin earlier gave the impression that you could change whether
messages for different log files could be specifically enabled for
a session. In practice that was true only for trace messages as the
session id and the bitmask telling what logfiles are enabled, were
copied to thread local storage only as far as trace messages were
concered.
The code for setting that information in place is quit short and
efficient, so there is really no reason not to do that always.
This also means that it always will be possible to get your hands
on the session object if there is a need for that.

LOGIF and skygw_write_log removed from server/core/*.c
...
LOGIF and skygw_write_log removed from server/core/*.c and
replaced with calls to MXS_(ERROR|WARNING|NOTICE|INFO|DEBUG).
This is a mechanism change, no updating of the actual message
has been performed.
Currently this causes a very small performance hit, since the
check whether the priority is enabled or not is performed in
the function that is called and not before the function is called.
Once all LOGIFs and skygw_write_logs have been replaced, the
behaviour will be altered back to what it was.
