If a command returns a nonzero exit status and VTYSH has a corresponding
command, VTYSH will skip executing its own version. If this happens in a
command that changes CLI nodes we get node desynchronization.

In some situations rtrlib does not release the locks for its internal
data structures before calling a callback. This can lead to deadlocks
when a lot of routes must be revalidated because the sync socket buffer
will fill up and block the rtrlib thread. The bgpd main thread then
waits for rtrlibs internal locks to be released indefinitely.
This is fixed by using nonblocking sockets instead of blocking ones and
setting a flag to revalidate everything, if it would block.

This commit removes various parts of the bgpd implementation code which
are unused/useless, e.g. unused functions, unused variable
initializations, unused structs, ...

If a cache server was added after rpki was started it's tr_socket would
not be initialized. This would lead to a segfault if the rtr manager
ever decides to switch to that socket or if rpki support is stopped.

The following types are nonstandard:
- u_char
- u_short
- u_int
- u_long
- u_int8_t
- u_int16_t
- u_int32_t
Replace them with the C99 standard types:
- uint8_t
- unsigned short
- unsigned int
- unsigned long
- uint8_t
- uint16_t
- uint32_t

We have a signed/unsigned comparison warning that this should
fix.
This should be ok because the range of input is a very limited
value and should never be of concern

This commit adds support for the RTR protocol to receive ROA
information from a RPKI cache server. That information can than be used
to validate the BGP origin AS of IP prefixes.
Both features are implemented using [rtrlib](http://rtrlib.realmv6.org/).
