bgpd: optimize aspath string representation and assegments handling

* bgp_aspath.h: Add str_len to struct aspath.
* bgp_aspath.c: Save the aspath string representation length and use it
  instead of strlen().
  (aspath_make_str_count) assign the string buffer directly for
  consistency with the string length and change the return type to void.
  (aspath_dup) use str_len and copy the string instead of calling
  aspath_make_str_count().
  (assegment_data_new) change from XCALLOC to XMALLOC. All users initialize
  the memory before use.
  (assegment_data_free) unused, removed.
  (aspath_intern) check that there's always a ->str pointer.
  (aspath_hash_alloc) reuse assegments and string representation instead of
  copying them.
  (aspath_parse) now aspath_hash_alloc does not dupes memory, free the
  temporary structures only if the aspath it is in the hash.
  (aspath_cmp_left) remove useless NULL initialization.
