Rusty Russell	18cd3dd2ad	lib/ccan/htable: benchmark against hsearch(3) ... Since that has a fixed hash table size and doesn't support delete, we can't do a thorough comparison, but we can insert and search.

Rusty Russell	0ac7deefbf	lib/ccan/htable: clean up interface, document htable_type better. ... We change from htable_new()/htable_free() to htable_init/htable_clear. We also change HTABLE_DEFINE_TYPE() to be the full name, without automatically prepending htable_.

Rusty Russell	1beb793664	lib/ccan/htable, strset: benchmarking tools. ...
