Applied base-0024-Sdo-directory-now-only-fetched-on-request
...
Sdo directory now only fetched on request.
The time-consuming SDO directory fetch during slave scan can now be
skipped by setting the EC_SKIP_SDO_DICT in globals.h. The directory
will now instead be fethed the first time an ethercat sdos command
is executed with the ethercat tool.

Improve synchronization of master->domains list
...
Introduce a new lock for synchronization of the master->domains list, and use
that instead of the big master_sem lock, improving real-time performance of
fx. ecrt_domain_process() when EoE thread is being shut down (or other
use-cases where master_sem is held for extended periods).
The following locking order is used:
* master->master_sem
* master->domains_lock
* master->io_sem
* domain->datagram_pairs_lock
Meaning that it is allowed to take domains_lock while holding master_sem, and
it is allowed to hold domains_lock while locking io_sem and
datagram_pairs_lock.
[RV: For now, the lockdep_assert_held() annotations are commented out,
since they don't compile with CONFIG_PROVE_LOCKING and (the default)
--disable-rtmutex.]

Clarify purpose of master->io_sem
...
In order to ensure proper use of locking, the purpose of each mutex/semaphore
must be clear and documented.
This is my best guess. The master->io_sem has a simple purpose, synchronizing
access to the master->datagram_queue list structure.
