libCom: Fix msgbufGetNode() in errlog.c
...
Systems that generate large numbers of errlog messages or have a slow
message listener could overwrite older messages in the message buffer
after the buffer wraps. This also corrects and annotates the test
code to describe what's being checked.

libCom: Fix errlogPrintf() assert fail at shutdown
...
If errlogPrintf() gets called during shutdown, it can cause a
recursive assert failure.

libCom/errlog: Clean up possible problem at shutdown.
...
Don't use epicsMutexMustLock() in msgbufGetFree().
When we're shutting down, the pvtData.msgQueueLock gets destroyed.
This makes msgbufGetFree() return NULL if the lock is dead.
The epicsMutexMustLock() routine asserts(), which recurses...

libCom/errlog: Rewrote msgbufGetNode() to use buffer better.
...
Michael Davidsaver pointed out that the original algorithm used is
dumb, it can't reuse empty space at the beginning until all messages
have been drained. This new version can, and is more efficient.

errPrintf() newline fix.
...
errPrintf() was adding a newline when writing to the err log buffer,
but not when printing to the screen. This results in the error
message running together with the next line. Added a newline to the
stderr output.

2) added errSymLookup function with these improvements

o return void and always copy a string into the users buffer. If the error code cant
be found then copy in a message with the error code's raw numbers in it.
3) removed prototypes for nonexistent fuinctions from header file
