41b21bfa60 *: have daemons call frr_fini() at termination
Fix a number of library and daemon issues so that daemons can
call frr_fini() during normal termination. Without this,
temporary logging files are left behind in /var/tmp/frr/.

Changes:

- Apply mask to prefix when storing it in the data structures. We
  can't just add a validation for it otherwise it will break old

Changes:
- Refactor list entry deletion to use a function that properly notifies
  route map on deletion (fixes a heap-use-after-free).
- Prefix list entry wild card sets `le` to maximum IP mask value and
  `any` is a boolean.
- Fix prefix list trie removal order (in `prefix_list_entry_update_start`).
- Let only the `any` callback change the value of field `any`.

744ad1afb4 lib: properly apply prefix list entries
After the commands started working I noticed that prefix lists were
still not working and displaying incorrect information in
`show ip prefix-list`.

Turns out `any` must be set to `0` when a prefix is set and the prefix
entry **must** be installed in the prefix list head.

a7b2821884 lib: fix prefix list installation
Based on the function `prefix_list_entry_add` and
`prefix_list_entry_delete` it was created two functions to replicate
its functionality without the assumption we are always alocating a new
prefix list entry.

Since the prefix list entry is stored in the YANG private data
structures, we want to avoid the allocation/free of memory that is
hold by the schema.

Every time a prefix list entry values change we must call
`prefix_list_entry_update_start` to uninstall the entry from prefix
list internal structures and then call
`prefix_list_entry_update_finish` to put them back.

The variable `installed` in the prefix list entry tracks the
installation status of the internal structure. It is possible that a
user unconfigures or forgets to add a `prefix` value and so we can't
install the entry until then.

c7d3de9ff2 lib: add 'no ... remark LINE' commands
Implement the commands `no ... remark LINE` for cisco and zebra style
access lists to match `ipX prefix-list description LINE` command set.

It useful when you just want to go through the command history and
prepend a `no` to a `remark` or `description` command. Example:

```
access-list foo remark just another acl
!
! ...
!
! Suddenly we decide we no longer think that remark is useful,
! lets press up key to find that line in history and append `no`:
no access-list foo remark just another acl
