If at least one community alias is configured, then let's do the work,
otherwise we don't need to spend time on splitting stuff and creating
a new string.
This should improve the performance.

Add a hash_clean_and_free() function as well as convert
the code to use it. This function also takes a double
pointer to the hash to set it NULL. Also it cleanly
does nothing if the pointer is NULL( as a bunch of
code tested for ).

Firstly, *keep no change* for `hash_get()` with NULL
`alloc_func`.
Only focus on cases with non-NULL `alloc_func` of
`hash_get()`.
Since `hash_get()` with non-NULL `alloc_func` parameter
shall not fail, just ignore the returned value of it.
The returned value must not be NULL.
So in this case, remove the unnecessary checking NULL
or not for the returned value and add `void` in front
of it.
Importantly, also *keep no change* for the two cases with
non-NULL `alloc_func` -
1) Use `assert(<returned_data> == <searching_data>)` to
ensure it is a created node, not a found node.
Refer to `isis_vertex_queue_insert()` of isisd, there
are many examples of this case in isid.
2) Use `<returned_data> != <searching_data>` to judge it
is a found node, then free <searching_data>.
Refer to `aspath_intern()` of bgpd, there are many
examples of this case in bgpd.
Here, <returned_data> is the returned value from `hash_get()`,
and <searching_data> is the data, which is to be put into
hash table.

This has already been a requirement for Solaris, it is still a
requirement for some of the autoconf feature checks to work correctly,
and it will be a requirement for `-fms-extensions`.

Add a bit of code to allow for auto-completion of the community
alias command when attempting to use it for show commands.
example:
eva(config)# bgp community alias 11:22 FOO
eva(config)# end
eva# show bgp ipv4 uni alias
ALIAS_NAME BGP community alias
FOO

Show alias name instead of numerical value in `show bgp <prefix>. E.g.:
```
root@exit1-debian-9:~/frr# vtysh -c 'sh run' | grep 'bgp community alias'
bgp community alias 65001:123 community-1
bgp community alias 65001:123:1 lcommunity-1
