Since f60a1188 we store a pointer to the VRF in the interface structure.
There's no need anymore to store a separate vrf_id field.

Remove mid-string line breaks, cf. workflow doc:
.. [#tool_style_conflicts] For example, lines over 80 characters are allowed
for text strings to make it possible to search the code for them: please
see `Linux kernel style (breaking long lines and strings)
<https://www.kernel.org/doc/html/v4.10/process/coding-style.html#breaking-long-lines-and-strings>`_
and `Issue #1794 <https://github.com/FRRouting/frr/issues/1794>`_.

1. The socket() call replaced with vrf_socket() in open_packet_socket().
2. One new isisd privileges is added in zebra_capabilities_t [].

the buffer to read from the socket when processing an incoming
packet was hardcoded to be of size 8192. If the mtu of the
interface is greater than that and hello padding is enabled
on that circuit, the hello message will be truncated, and this
will cause the adjacency establishment to fail. fix this by
using a large enough stack buffer instead

Historically, isisd has been carrying around its own red-black tree to
manage its LSP DB in. This replaces that with the newly-added
DECLARE_RBTREE_*. This allows completely removing the dict_* code.

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

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.

Due to the time window between opening socket and binding it to an interface, the same hello
packet is delivered on multiple interfaces, unique socket per circuit is not yet established.
When such hellos get processed, they form incorrect adjacencies. So, drop the packet that is
received on multiple interfaces because the socket for the circuit is yet to bind to an interface.

this fixes a bunch of issues found by Coverity SCAN and flagged as
"high" impact -- although, they're all rather minute issues.
* isisd/isis_adjacency.c: one superfluous check, one possible NULL deref
* isisd/isis_circuit.c: two prefix memory leaks
* isisd/isis_csm.c: one missing break
* isisd/isis_lsp.c: one possible NULL deref
* isisd/isis_pfpacket.c: one error-case fd leak
* isisd/isis_route.c: one isis_route_info memory leak
* isisd/isis_routemap.c: one... fnord
* isisd/isis_tlv.c: one infinite loop

The socket is only created once when an interface is brought up, and the
multicast groups were joined according to configuration at that point.
This breaks when later switching an interface to another IS-IS level.
Since, for a separate conformance issue (ANVL ISIS-6.4), we should be
inspecting the destination address anyway, the simplest fix here is to
just join all groups unconditionally. There shouldn't be much traffic
on these anyway, worst case we might be picking up some unrelated
multicast groups due to NIC filter aliasing though...

this fixes warnings from vtysh extract.pl by making sure the isis method
files always 'work'. (previously, extract.pl would grab unselected isis
method sources and then complain about missing headers)
