Previously, there was no way to clear AMSG when setting a no-alarm
status: it kept the last error message, and it is strange to have a
record that has no alarm while showing an error. With this change, the
NAMSG field is treated the same as NSTA and NSEV: they are cleared when
their content is moved to STAT, SEVR, and AMSG.
Previously, linking a field of e.g. a calc record to itself
(calc.INPA = calc.A) directly or through a chain of other records
that support to follow the link for attributes like units, precision
caused an infinite recursion and crashed the ioc.
Affected records: calc, calcout, seq, sub and aSub
Also added support for seq link 0 fields which had been added meanwhile.
Save/restore dbAddr::pfield around callbacks to
avoid corruption if CB forgets to restore.
Need to peak at dbChannel.h during libCom build.
So generate dbCoreAPI.h early, and add extra
-I to source location when compiling dbTrapWrite.c
This enables us to use toctrees, which informs Sphinx on the global
documentation structure, and removes warnings about not-included
documents.
The old ComponentReference.pod was kept, in order to not break the old
HTML output, but the new Markdown file is used as source for the
generated markdown files in doc/
Markdown can be generated from .pod and .dbd.pod files.
Markdown will be generated and installed by "make inc".

Besides being deprecated in C++11 and removed in C++17, the intended use
case for this was always wrong, since std::unexpected() is called by the
C++ runtime when a function throws an exception that was not specified
in its "dynamic exception specification", which is different from an
exception thrown by user code which wasn't caught [1,2]. Using abort()
keeps the same behavior, but with the intended semantics.
We don't use std::abort() to simplify backwards compatibility.

Copyright was previously assigned based on the author's email, which had
been modifified by repository conversion from CVS to git. This rectifies
the situation by assigning copyright to the authors employer at the time
of creation of the file.
