Make the *iSoftCallback devices allocate a single buffer for private
storage instead of several, and cope with calloc failures without
suspending the IOC thread.
Added new PN_LINK type in link.h, make dbStaticLib display it.
Made all device support extended so links can be changed at runtime.
Modified startup so add_record() always called before regular link processing.
Incomplete, stilll need to add MS/MSS/MSI support, currently disabled.
Replaced Dirk's fixed precision=2 and limit=10 seconds with
global variables which can be set for each IOC. Also changed
the upper control limit for delay fields from 10 to 100,000.
When generating a DBE_PROPERTY event because of a modified
enum string, also post DBE_VALUE and DBE_LOG events if the
record is currently in that particular state.
