cmdline: use IPv6 address structure

The previous commits introduced a new rte_ipv6_addr structure without
any alignment requirements. It is not compatible with the in6_addr POSIX
type available in netinet/in.h.

The main issue is that in6_addr is not uniform on all platforms which
causes unaligned access warnings when compiling without
-Wno-address-of-packed-member (set in dpdk by default).

In order to have a consistent code base, replace in6_addr with
rte_ipv6_addr in the cmdline library. Update all code accordingly.

cmdline: increase input buffer size

DPDK defines cmdline input buffer size to 512 characters.
That buffer size can be too small for long application input.
For example, the following flow template API testpmd command is 444
bytes long:
```
flow queue 0 create 0 template_table 1000 \
pattern_template 0 actions_template 0 postpone no \
pattern eth / ipv4 / udp / end \
actions modify_field op set dst_type tag dst_level 0 dst_offset 0 \
src_type value src_value 0x31 width 32 / \
modify_field op set dst_type ipv4_src src_type value \
src_value 10101010 width 32 / modify_field op add dst_type \
ipv4_ttl dst_level 0 dst_offset 0 src_type value \
src_value ff width 8 / count / jump group 100 / end
```

The patch increases cmdline input buffer size to the LINE_MAX value,
which typically is 2048 bytes.
