Merge lp:~epics-core/epics-base/postdbrprop into lp:~epics-core/epics-base/3.15

[mdavidsaver]

(This branch should have been named "postdbeprop", but I mis-typed and don't want the trouble of correcting this now)

The branch adds posting of DBE_PROPERTY events when CA metadata/property fields are written with dbPut(). These fields are marked in the recordtype's .dbd file with "prop(YES)".

Changes are made to recognise the prop() field attribute and store it. The attribute is added to all Base recordtypes except mbbi and mbbo where it is not added for the *ST fields as this is already handled by the recordtype's support code.

Also, dbPut() is modified to post a monitor whenever a "prop(YES)" field is written. No attempt to detect field value changes is made. The event is posted for all monitors on the record with DBE_PROPERTY, not just the VAL field. This is done to support recordtypes with more than one VAL type field.

+<h3>Post DBE_PROPERTY events automatically</h3>
+
+<p>A new record field attribute "prop(YES)" is added to identify fields
+holding CA meta-data.  Changes to fields so marked will cause a event
+to be sent to all subscriptions to that record for DBE_PROPERTY.
+Meta-data fields are marked for all Base recordtypes.</p>

 <h3>errlogRemoveListener() routine changed</h3>
