Restore previous behavour that empty string
is equivalent to numeric zero.
epicsParse*() returns S_stdlib_noConversion
where previously strtoul() did not.

Command 'dbjlr <record|*> <level>' calls the report method for
all JSON links in all records, or in one named record.
Added level and indent arguments to the jlif::report() method.
Added jlif::map_children() method for recursing through all
JSON links, plus dbJLinkMapChildren() and dbJLinkMapAll() APIs.
Implemented the report and map_children methods in the const
and calc link types.
When representing a link field as a long string (.INP$)
we have to pick some size limit for the buffer.
Previously this was the max length of a PV name + 12 chars,
but with JSON links that's not big enough.
This commit sets it to 1KB and defines a macro so it will be
easier to change in the future if necessary.
This counter is indicates when we've finished parsing a link,
and needs to be stored with link rather than the parser so it
keeps its value while parsing embedded links. This fixes the
embedded links bug.
Also removed the limit on a link name's length.
Added dbFreeLinkInfo(), use everywhere to release dbLinkInfo resources.
Renamed link_type => expected_type in db[Can]SetLink(),
my brain understands this name faster.
This required a change to the lset::getValue arguments, removing
the pstat and psevr pointers. Links can still return a non-zero
value from getValue and trigger a LINK:INVALID alarm, but for any
other alarm settings they must manipulate the record themselves.
The JSON parser passes string arguments with a length
instead or nil-terminating them. These routines make it
simple to copy such strings into either permanent or
temporary storage.
* Added new lset::openLink() method, called on JSON_LINKs only
* Cleanup in dbJLink.c to prevent memory leaks.
* Removed jlif::start_parse() method.
* Renamed jlif::end_parse() to end_child, which will be called on
the parent link when a child link has succesfully finished parsing.
