Root has problems with loading dictionaries if multiple threads are running.
Force load some dictionaries we'll need during initialization.

For easy access to the Event Reference through EventStore

Enable thread-safety checking.

Similar change to !35801.

Prior to this change log file diffs in unit tests compared the reference file to the current
output, rather than the other way around, so that lines in the log removed due to local
changes are marked with a `+` in the diff output and lines added to the log are marked with
a `-`.

This commit switches the order of comparison with the aim of making the output more intuitive.

Enable thread-safety checking.

The code which builds MBTS readout geometry has been factored out from the EndcapCryostatConstruction,
so that now it can be shared by the old-style and new-style (SQLite based) LAr detector factories.

Also fixed SqliteRecordset so that it does not print an ERROR message if the requested
table is not found in the SQLite database.

Avoid redundant set lookup.

Enable thread-safety checking and fix identified issues.

Prefer to initialize members in an initializer list.

The event selectors keep track of the sourceIDs for events being processed,
using the BeginProcessing and EndProcessing incidents.  When handling
each incident, it queries the event store to find the sourceID.

EndProcessing is fired by the event loop manager after all event processing
is completed.  In particular, in MT jobs, this incident is fired from
the event loop thread after the scheduler has reported that an event
has completed.

However, we would like to give the event loop manager the possibility 
of clearing the event store in the threaded part of event processing.
If that happens, the event store will already have been cleared by the
time EndProcessing is fired, so retrieving the sourceID will fail.

Change the event selectors so that they save the sourceID when
handling the BeginProcessing incident (using SlotSpecificObj)
and use that at EndProcessing rather than trying to retrieve
it again from the event store.

New property "AthenaPoolCnvSvc.maxDHFormCacheSize" controls the max size
of DHForm cache in DataHeaderCnv. Default size is 100. The setting works
for each input file.
Introduced to avoid excesive memory usage in case of files with many
large DHForms. (noticed in ATLASRECTS-6370)

Prefer preincrement to postincrement for iterator classes.
