Andrew Johnson 1d99ad6cfc Move closer to having pluggable link types. 
All link types now have a plink->precord pointer.
Add link support entry tables for const, DB and CA link types.
Route all link I/O options through the new plink->lset.

Michael Davidsaver 504665bf09 iocInit: move dbCaShutdown earlier

be called from iocShutdown.  Place it
after callback shutdown.

Andrew Johnson a5e1f367d6 Merged cbshutdown changes from 3.15 branch, revno 12690 2015-07-16 11:54:40 -05:00
Michael DavidsaverandAndrew Johnson fefe6fd1fc Fix shutdown issues with scan and callback. 
The main reason for this merge proposal is the change to "public" API functions.

Use atomic counter to resolve data race on threadsRunning in callback.

Split up callbackShutdown() and scanShutdown() into two phases *Stop() and
*Cleanup(). The *Stop() functions signal worker threads, and wait for them to
exit. The *Cleanup() functions actually reclaim global resources.

These two mechanisms have couplings which are quite complex. I/O Intr scans
involve both scan lists and callbacks.

Michael Davidsaver d35780888a iocInit: only teardown from iocBuildIsolated() 
iocShutdown() should only stop threads and cleanup
if the IOC was started with iocBuildIsolated().
If iocBuild() is used then only close CA links
as was done previously.

This is needed as some device support calls epicsExit()
(while holding a record lock).  This make it impossible
to run the full iocShutdown without deadlocking
in scan/callback shutdown, or segfaulting
in doFreeRecord() or dbLockCleanupRecords()
