Yup, it got removed because it doesn't include any field modifiers that
might have been used with the PV name, and because we changed the
internals slightly, so you will have to modify the caPutLog code to
match anyway.

> dbNameOfPV is used by caPutLog
In 3.15 the void * asTrapWriteMessage.serverSpecific pointer that gets
passed to the listeners is no longer a dbAddr*, it's now a dbChannel* so
to get the PV name all RSRV asTrapWriteListeners must call
    dbChannelName((dbChannel *) msg.serverSpecific)
instead, which returns a const char* holding the channel's full PV name.

I just updated the 3.15.1 AppDevGuide to correct this in the Access
Security chapter, although we haven't actually documented the dbChannel
API there yet (see dbChannel.h and post questions here until that gets
written, sorry).
