We should probably prevent any type of namespace collision
with something else.

Convert the `struct thread_master` to `struct event_master`
across the code base.

Effectively a massive search and replace of
`struct thread` to `struct event`. Using the
term `thread` gives people the thought that
this event system is a pthread when it is not

This is a first in a series of commits, whose goal is to rename
the thread system in FRR to an event system. There is a continual
problem where people are confusing `struct thread` with a true
pthread. In reality, our entire thread.c is an event system.
In this commit rename the thread.[ch] files to event.[ch].

Done with a combination of regex'ing and banging my head against a wall.

The int return value is never used. Modify the code
base to just return a void instead.

There's nothing that can be done here with an error. Try to make
Coverity understand that this is intentional.
(I don't know if the `(void)` will actually fix the coverity warning,
but I don't really have a better way to figure it out beyond just
getting this merged and waiting for a result...)

This replaces the external libsystemd dependency with... pretty much the
same amount of built-in code. But with one fewer dependency and build
switch needed.
Also check `JOURNAL_STREAM` for future logging integration.

Allow systemd to be informed about operational state so operators can
infer a bit about what is going on with FRR from the systemd status
cli.

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.

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.

We want the ability to start up quagga in a varied set of
environments. This needs to be done in SysV and systemd
startups. As such refactor the code to allow us to
allow end users to easily switch between the two
sysV:
edit the /etc/quagga/daemons file
service quagga [start|stop|reload|restart]
Systemd:
edit the /etc/quagga/daemons file
systemctl [start|stop|reload|restart] quagga

Modify the lib/ code to include the ability to interact
with systemd. Provide the ability to interact with
systemd's watchdog timer as well.
There is no code here that actually uses this change.
