This commit fixes possible integer overflow for
prev_idx in build_common_root() CID 350596
and
tbl8_idx in write_edge() CID 350597
Unintentional integer overflow (OVERFLOW_BEFORE_WIDEN)
overflow_before_widen: Potentially overflowing expression tbl8_idx * 256
with type int (32 bits, signed) is evaluated using 32-bit arithmetic,
and then used in a context that expects an expression of
type uint64_t (64 bits, unsigned).
Coverity issue: 350596, 350597
Fixes: c3e12e0f03 ("fib: add dataplane algorithm for IPv6")

Remove trailing blank lines. They serve no purpose and are just
editor leftovers.
These can cause git to complain about whitespace errors during merges.

Add fib implementation for ipv6 using modified DIR24_8 algorithm.
Implementation is similar to current LPM6 implementation but has
few enhancements:
faster control plane operations
more bits for userdata in table entries
configurable userdata size
