955357174f ldpd: Fix issue when starting up LDP with no configuration.
LDP would mark all routes as learned on a non-ldp interface.  Then
when LDP was configured the labels were not updated correctly.  This
commit fixes issues 6841 and 6842.

e7ff02539c lib: Note old ifindex on shutdown
If we have an interface configured in a daemon on shutdown
store the old ifindex value for retrieval on when it is
possibly recreated.

This is especially important for nexthop groups as that we
had at one point in time the ability to restore the
configuration but it was lost when we started deleting
all deleted interfaces.  We need the nexthop group subsystem
to also mark that it has configured an interface.

a251884bff lib: Allow nexthop simple display to take an alternate ifp name
The nexthop_group_write_nexthop_simple function outputs the
interface name, because we've stored the ifindex.  The problem
is that there are ephermeal interfaces in linux that can be
destroyed/recreated.  Allow us to keep that data and do something
a bit smarter to allow show run's and other show commands to continue
to work when the interface is deleted.

Wildcards bits have the opposite representation of a network mask,
example:

192.168.0.0/24 has the following netmask 255.255.0.0 and the wildcard
representation is 0.0.255.255.

To avoid future confusion lets put those definitions into a macro so we
know for sure which form to use.

deb95b373f lib, tools: fix reloading of key sub-context in key chains
When you add a key chain in the RIP configuration file and reload the
configurations via the frr-reload.py script, the script will fail and
the key chain will not appear in the running configuration. The reason
is that frr-reload.py doesn't recognize key as a sub-context.

Before this change, keys were generated this way:

    key chain test
     key 2
      key-string 123
     key 3
      key-string 456

With this change, keys will be generated this way:

    key chain test
     key 2
      key-string 123
     exit
     key 3
      key-string 456
     exit

This will allow frr-reload.py to see the key sub-context and correctly
reload them.

the decoding by flowspec, and the addition of a new attribute in policy

The commit also includes a check on fragment option, since dont fragment
bit does not exist in ipv6, the value should always be set to 0,
otherwise the flowspec rule becomes invalid.

24ed137c20 lib: adapt plugin to use new Sysrepo version
Sysrepo recently underwent a complete rewrite, where some substantial
architectural changes were made (the most important one being the
extinction of the sysrepod daemon). While most of the existing API
was preserved, quite a few backward-incompatible changes [1] were
introduced (mostly simplifications). This commit adapts our sysrepo
northbound plugin to those API changes in order for it to be compatible
with the latest Sysrepo version.

Additional notes:
* The old Sysrepo version is EOL and not supported anymore.
* The new Sysrepo version requires libyang 1.x.

Closes #6936

0fe5b904b7 lib: don't ignore error messages generated during the commit apply phase
While a configuration transaction can't be rejected once it reaches
the APPLY phase, we should allow NB callbacks to generate error
or warning messages when a configuration change is being applied.
That should be useful, for example, to return warnings back to
the user informing that the applied configuration has some kind of
inconsistency or is missing something in order to be effectively
activated. The infrastructure for this was already present, but the
northbound layer was ignoring all errors/warnings generated during
the apply/abort phases instead of returning them to the user. This
commit changes that.

In the gRPC plugin, extend the Commit() RPC adding a new
"error_message" field to the response type. This is necessary to
allow errors/warnings to be returned even when the commit operation
succeeds (since grpc::Status::OK doesn't support error messages
like the other status codes).

d142453d6b lib: Properly handle POLLERR from poll()
There are situations where POLLERR will be returned.  But
since we were not handling it.  Thread processing effectively
is turned into an infinite loop, which is bad.

Modify the code so that if we receive a POLLERR we turn it
into a read event to be handled as an error from the handler
function.

This was discovered in pim:
