In preparation to Segment Routing:
- Update the management of Traffic Engineering subTLVs to the new tlvs parser
- Add Router Capability TLV 242 as per RFC 4971 & 7981
- Add Segment Routing subTLVs as per draft-isis-segment-routing-extension-25
Modified files:
- isis_tlvs.h: add new structure to manage TE subTLVs, TLV 242 & SR subTLVs
- isis_tlvs.c: add new functions (pack, copy, free, unpack & print) to process
TE subTLVs, Router Capability TLV and SR subTLVs
- isis_circuit.[c,h] & isis_lsp.[c,h]: update to new subTLVs & TLV processing
- isis_te.[c,h]: remove all old TE structures and managment functions,
and add hook call to set local and remote IP addresses as wellas update TE
parameters
- isis_zebra.[c,h]: add hook call when new interface is up
- isis_mt.[c,h], isis_pdu.c & isis_northbound.c: adjust to new TE subTLVs
- tests/isisd/test_fuzz_isis_tlv_tests.h.gz: adapte fuuz tests to new parser

The original check would always evaluate to false since
ISIS_PREFIX_SID_VALUE and ISIS_PREFIX_SID_LOCAL have different
values. Use !! to normalize the return value of the individual
checks to either 0 or 1, making the code do what was intended
(ensure the V/L flags are both 0 or 1).

The correct cast for these is (unsigned char), because "char" could be
signed and thus have some negative value. isalpha & co. expect an int
arg that is positive, i.e. 0-255. So we need to cast to (unsigned char)
when calling any of these.

The RFC states we can send only up to 16 v6 addresses in a hello packet
and cannot send sub tlv's of that type.

This is necessary to avoid a name collision with std::for_each
from C++.

The Sub-TLVs of the Extended IPv4 reachability TLV were not being
displayed as expected. Fix this.

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 original isisd code did not distinguish between
authentication_failure and authentication_type_failure, so
additional code had to be added to differentiate between the two
and to return the raw_pdu as requested by the IETF YANG model.

This reverts commit 48944eb65e.
We're using GNU C, not ISO C - and this commit triggers new (real)
warnings about {0} instead of bogus ones about {}.

To flood the tier calculated by the fabric locality detection,
OpenFabric makes use of TLV 150, defined in
draft-shen-isis-spine-leaf-ext-06, so add support for that TLV.

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

Convert the list_delete(struct list *) function to use
struct list **. This is to allow the list pointer to be nulled.
I keep running into uses of this list_delete function where we
forget to set the returned pointer to NULL and attempt to use
it and then experience a crash, usually after the developer
has long since left the building.
Let's make the api explicit in it setting the list pointer
to null.
Cynical Prediction: This code will expose a attempt
to use the NULL'ed list pointer in some obscure bit
of code.

This fixes the broken indentation of several foreach loops throughout
the code.
From clang's documentation[1]:
ForEachMacros: A vector of macros that should be interpreted as foreach
loops instead of as function calls.
