Port ssl_util_table.[ch] to Apache 2.0 by just removing all platform

depended code (table_read, table_write). This is possible because this
table library is local to mod_ssl and inside mod_ssl this library is
used for manipulating hash tables inside shared memory segments only. So
we can just get rid of the unportable parts at all.
