bgpd: add instance delete & config write hooks
Both of these hooks are necessary for proper operation of extensions
that need to latch on to a particular instance.
- without the delete hook, it's impossible to get rid of stale

- the config-write hook is necessary because per-instance config needs
to be written inside the "router bgp" block to have the appropriate
context; adding a separate config node can't do that.

build, lib: bump libyang requirement version to >= 0.16.105
After ~4 months of deprecation period [1], drop support for older
libyang versions that don't support embedded extensions.
In addition to support for embedded extensions, libyang 0.16-r3
contains several bug fixes and performance improvements compared
to libyang-0.16-r1. It was about time to update.
ripd: fix problems with the "ip rip authentication" command
libyang-0.16-r3 doesn't allow the creation of data nodes if their
corresponding "when" statement (if any) resolves to false. This
change broke the "ip rip authentication" command.
This commit adapts this command so that it's not affected by the
new libyang stricter validation checks.
libyang-0.16-r3 contains a commit[1] that changed the autodelete
behavior of subtrees when validating data. A few FRR commands were
affected by this change since they relied on the old autodelete
behavior.
To fix these commands, use the LYD_OPT_WHENAUTODEL flag when
validating data to restore the old autodelete behavior (which adds
a lot of convenience for us).
