epics-base/src/std/rec/mbboDirectRecord.c
Ben Franksen cc946b760c partly fix lp:1666924, i.e. for rset only, as described in the ticket 
This means:

* typed method definitions for struct rset
* using REC_TYPE macro in place of dbCommon
* define REC_TYPE as dbCommon unless defined
* in record supports, define REC_TYPE before including epics headers
* fix a few method types in record supports (e.g. void* -> REC_TYPE*)
* fix the type errors gcc finds in dbAccess.c and dbConvert.c
