Implement common code for debug config output and remove daemon-specific
code that is duplicated everywhere.

The debug library allows to register a `debug_set_all` callback which
should enable all debugs in a daemon. This callback is implemented
exactly the same in each daemon. Instead of duplicating the code, rework
the lib to allow registration of each debug type, and implement the
common code only once in the lib.

Also an empty (thus non-replace) notify selectors message shouldn't
clear the selectors, it should just do nothing.

- call the new notification hooks when backends call the old notification
posting API.

Currently, YANG notification processing is done using a special type of
callbacks registered in backend clients. In this commit, we start using
regular northbound infrastructure instead, because it already has a
convenient way of registering xpath-specific callbacks without the need
for creating additional structures for each necessary notification. We
also now pass a notification data to the callback, instead of a plain
JSON. This allows to use regular YANG library functions for inspecting
notification fields, instead of manually parsing the JSON.

Current code assumes that notification is always sent in stripped JSON
format and therefore notification xpath starts at the third symbol of
notification data. Assuming JSON is more or less fine, because this
representation is internal to FRR, but the assumption about the xpath is
wrong, because it won't work for not top-level notifications. YANG
allows to define notification as a child for some data node deep into
the tree and in this case notification data contains not only the
notification node itself, but also all its parents.
To fix the issue, parse the notification data and get its xpath from its
schema node.

When the daemon is partially mgmtd-converted, it receives configuration
from vty and mgmtmd simultaneosly. This configuration must be
synchronized.

Replace operation removes the current data node configuration and sets
the provided value. As current northbound code works only with one
xpath at a time, the operation only makes sense to clear the config of
a container without deleting it itself. However, the next step is to
allow passing JSON-encoded complex values to northbound operations which
will make replace operation much more useful.

Currently, there's a single operation type which doesn't return error
if the object doesn't exists. To be compatible with NETCONF/RESTCONF,
we should support differentiate between DELETE (fails when object
doesn't exist) and REMOVE (doesn't fail if the object doesn't exist).

Currently, there's no difference between CREATE and MODIFY operations.
To be compatible with NETCONF/RESTCONF, add new CREATE_EXCL operation
that throws an error if the configuration data already exists.

lib, mgmtd: respect base xpath in mgmtd
|
|
`nb_cli_apply_changes` can be called with base xpath which should be
prepended to xpaths of every change in a transaction. This base xpath is
respected by regular northbound CLI but not by mgmtd. This commit fixes
the problem.

Batch IDs are only used to verify that all messages were received and
processed by a backend. It's not necessary to do that as we use reliable
stream transport - messages can't be dropped or received out of order.
This commit also fixes possible race condition that can happen if
one backend process messages slower than other backends.

- Cannot have 2 cmd_node's with same .node number. Install the mgmtd
client library debug nodes (client frontend and client backend) using
new unique node numbers. Fixes memleaks.

mgmtd: improvements in logging and commentary

lib: mgmtd: make error handling more robust
|
|
- log names of datastores not numbers
- improve logging for mgmt_msg_read
- Rather than use a bool, instead store the pending const string name of
the command being run that has postponed the CLI. This adds some nice
information to the logging when enabled.

Code is no longer using a global FE "client context", and instead
creates client objects, rename the structure and it's uses to reflect this.
Remove an obfuscating abstraction layer whose existence was entirely
based on using a uintptr_t rather than a pointer to an declared-only struct.
Change multi-duty "params" structure into a single duty callbacks one.
Remove unsupported API code.
