EPICS Base 3.14.8

Bug Description

In R3.14.7 there is a new epicsExit facility. The
DB CA link subsystem should install an epicsExit handler
that calls ca_context_destroy() so that DB CA link related
CA circuits are shut down during a soft IOC reboot.

When dbCa was modified to call ca_context_destroy, a crash occured
when a call to db_post_event was made for channel access links to local records.

To do a complete cleanup at shutdown would be a major effort and is not planned
for the 3.14 releases.

For 3.14 there are no currently no plans to fix this since it probably means a complete cleanup of all resourses used by database records.
