When vtysh sends 'exit' to a daemon, we set the vty->status to
VTY_CLOSE but never actually close the connection. Lovely.

The xml2cli.pl script was useful years ago when the vty code was very
rudimentary. This is not the case anymore, so convert all ldpd CLI
commands to use DEFUNs directly and get rid of the XML interface.
The benefits are:
* Consistency with the other daemons;
* One less build dependency (the LibXML perl module);
* Easier to add new commands.

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.

Shows known values in the appropriate naming domain when the user hits
<?> or <Tab>. This patch only works in the telnet CLI, the next patch
adds vtysh support.
Included completions:
- interface names
- route-map names
- prefix-list names

Passing stack value to thread_add_* causes thread->ref to become an
invalid pointer when the value goes out of scope
Signed-off-by: Quentin Young <qlyoung@cumulusnetworks.com>
Pass pointer to pointer instead of assigning by return value. See
previous commit message.
To ensure that the behavior stays functionally correct, any assignments
with the result of a thread_add* function have been transformed to set
the pointer to null before passing it. These can be removed wherever the
pointer is known to already be null.

The way thread.c is written, a caller who wishes to be able to cancel a
thread or avoid scheduling it twice must keep a reference to the thread.
Typically this is done with a long lived pointer whose value is checked
for null in order to know if the thread is currently scheduled. The
check-and-schedule idiom is so common that several wrapper macros in
thread.h existed solely to provide it.
This patch removes those macros and adds a new parameter to all
thread_add_* functions which is a pointer to the struct thread * to
store the result of a scheduling call. If the value passed is non-null,
the thread will only be scheduled if the value is null. This helps with
consistency.
A Coccinelle spatch has been used to transform code of the form:
if (t == NULL)
t = thread_add_* (...)
to the form
thread_add_* (..., &t)
The THREAD_ON macros have also been transformed to the underlying
thread.c calls.

These have copies in vtysh that do the node-switch locally and are
listed in extract.pl's ignore list. The ignore list however is
redundant since DEFUN_NOSH does the same thing...
ldpd is a bit hacky, but Renato is reworking this anyway.

Centralise read_config/daemonize/dryrun/pidfile/vty_serv into libfrr.
This also makes multi-instance pid/config handling available as part of

This moves all install_element calls into the file where the DEFUNs are
located. This fixes several small related bugs:
- ospf6d wasn't installing a "no interface FOO" command
- zebra had a useless copy of "interface FOO"
- pimd's copy of "interface FOO" was not setting qobj_index, which means
"description LINE" commands would fail with an error
The next commit will do the actual act of making "foo_cmd" static.
