```
mgmtd/mgmt_be_adapter.c:86:5: error: "HAVE_RIPD" is not defined, evaluates to 0 [-Werror=undef]
86 | #if HAVE_RIPD

```
I have searched the code, there is only three places need to be fixed.

Let's make the compiler happy, even though there is no problem.

New back-end clients may need to add notification static allocations so
we should have it available for those users, rather than requiring the
new user delve into the mgmtd infra and modify it themselves.

Backend "subscribe" API allows daemons to dynamically register xpaths
they are interested in. Such xpaths are not stored in hardcoded
config/oper xpath arrays so this function fails to understand that a
backend daemon is interested in them. Fix by using dynamic xpath maps
instead which store both hardcoded and dynamic xpaths.

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.

There are places, where we can receive an existing commit transaction.
If we don't check that the request already exists, it gets overwritten
and we start having problems with transaction refcounters. Forbid having
multiple configuration sessions simultaneously.

Also change `be_client_xpaths` to `be_client_config_xpaths` referred in the doc
to make much clearer it's use (since there's a separate `be_client_oper_xpaths`.

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.

The config is always applied fully, all batches are included. There's no
need to pass a list of applied batches as it always contains all of
them.
