028fff6edd classify: Use fixed size bit vector 
The vector was already limited to MAX_NUM_PROTOS (512) entries or 64 bytes
in the old code. Now it uses that size right from the start which avoids
reallocating it later when entries are added.

The old code which reallocated the vector to expand it was buggy because
the realloc function can return a different pointer, but the code still
used the original pointer to reset the new bits.

Function ExpandBitVector is now unused and therefore removed.
