With a new version of clang 6.0, the compiler is detecting more
issues where we may be possibly be truncating the output string.
Fix by increasing the size of the output string to make the compiler
happy.

This allows running the daemons inside of Linux network namespaces
without messing with an additional mount/fs namespace (or a ton of
options).

adds a new all-daemon "debug memstats-at-exit" command. Also saves
memstats to a file in /tmp, useful if a long-running daemon is having
weird issues (e.g. in a user install).
Fixes: #437

Start creating a counterpart to frr_init and frr_late_init.
Unfortunately, some daemons don't do any exit handling, this doesn't
change that just yet.

This adds "@tcp" as new choice on the -z option present in zebra and the
protocol daemons. The --enable-tcp-zebra option on configure is no
longer needed, both UNIX and TCP socket support is always available.
Note that @tcp should not be used by default (e.g. in an init script),
and --enable-tcp-zebra should never have been in any distro package
builds, because
**** TCP-ZEBRA IS A SECURITY PROBLEM ****
It allows arbitrary local users to mess with the routing table and
inject bogus data -- and also ZAPI is not designed to be robust against
attacks.

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.

This adds a "-M" option to each daemon, to load dynamic modules at
startup. Modules are by default located in /usr/lib/frr/modules (lib64
if appropriate). Unloading or loading at runtime is not supported at
this point to keep things simple.

The protocols enum serves no purpose other than adding potential for
bugs and making it complicated to add a new protocol... nuke.

Contains the fetch-and-run-thread logic, and vty startup (which is the
last thing happening before entering the main loop).

Centralise read_config/daemonize/dryrun/pidfile/vty_serv into libfrr.
This also makes multi-instance pid/config handling available as part of
the library. It's only wired up in ospfd, but the code is in lib/.

Start centralising startup & option parsing into the library.
FRR_DAEMON_INFO is a bit weird, but it will become useful later (e.g.
for killing the ZLOG_* enum, and having the daemon name available)
