Mgmtd makes use of libyang's internal ietf-yang-library module to add
support for said module to FRR management. Previously, mgmtd was loading
this module explicitly; however, that required that libyang's
`ietf-yang-library.yang` module definition file be co-located with FRR's
yang files so that it (and ietf-datastore.yang) would be found when
searched for by libyang using FRRs search path. This isn't always the
case depending on how the user compiles and installs libyang so mgmtd
was failing to run in some cases.
Instead of doing it the above way we simply tell libyang to load it's
internal version of ietf-yang-library when we initialize the libyang
context.
This required adding a boolean to a couple of the init functions which
is why so many files are touched (although all the changes are minimal).

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.

In case of config rollback is enabled,
record northbound transaction based on a control flag.
The actual frr daemons would set the flag to true via
nb_init from frr_init.
This will allow test daemon to bypass recording
transacation to db.

And again for the name. Why on earth would we centralize this, just so
people can forget to update it?

Same as before, instead of shoving this into a big central list we can
just put the parent node in cmd_node.

There is really no reason to not put this in the cmd_node.
And while we're add it, rename from pointless ".func" to ".config_write".

Our two northbound tools don't have embedded YANG modules like the
other FRR binaries. As such, ly_ctx_set_module_imp_clb() shouldn't be
called when the YANG subsystem it being initialized by a northbound
tool. To make that possible, add a new "embedded_modules" parameter
to the yang_init() function to control whether libyang should look
for embedded modules or not.
With this fix, "gen_northbound_callbacks" and "gen_yang_deviations"
won't emit "YANG model X not embedded, trying external file"
warnings anymore.

The correct cast for these is (unsigned char), because "char" could be
signed and thus have some negative value. isalpha & co. expect an int
arg that is positive, i.e. 0-255. So we need to cast to (unsigned char)
when calling any of these.

Confirmed commits allow the user to request an automatic rollback to
the previous configuration if the commit operation is not confirmed
within a number of minutes. This is particularly useful when the user
is accessing the CLI through the network (e.g. using SSH) and any
configuration change might cause an unexpected loss of connectivity
between the user and the managed device (e.g. misconfiguration of a
routing protocol). By using a confirmed commit, the user can rest
assured the connectivity will be restored after the given timeout
expires, avoiding the need to access the router physically to fix
the problem.
When "commit confirmed TIMEOUT" is used, a new "commit" command is
expected to confirm the previous commit before the given timeout
expires. If "commit confirmed TIMEOUT" is used while there's already
a confirmed-commit in progress, the confirmed-commit timeout is
reset to the new value.
In the current implementation, if other users perform commits while
there's a confirmed-commit in progress, all commits are rolled back
when the confirmed-commit timeout expires. It's recommended to use
the "configure exclusive" configuration mode to prevent unexpected
outcomes when using confirmed commits.
When an user exits from the configuration mode while there's a
confirmed-commit in progress, the commit is automatically rolled
back and the user is notified about it. In the future we might
want to prompt the user if he or she really wants to exit from the
configuration mode when there's a pending confirmed commit.
Needless to say, confirmed commit only work for configuration
commands converted to the new northbound model. vtysh support will
be implemented at a later time.

I see lots of the same code being copy-pasted and slightly tweaked for
string processing all over the codebase. Time to start aggregating these

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.
