8f8d03df46 add perllike hash function for strings 
This also adds a new API json_global_set_string_hash() which permits
to select the hash function. The default one is the only one that was
previously present. So there are no changes to existing apps, and the
new hash function needs to be explicitely be opted in. Especially for
smaller strings, the perllike functions seems to be around twice as
fast as the other one, with similarly good results in value distribution.

2d549662be add json_object_object_add_ex() API 
This provides more control over some detail aspects, many
of which are performance related.

4a2cd966f5 Add NULL-safe lookup function 
New lh_table_lookup_ex() method protects itself against null pointers
and invalid objects being passed in.

64c0ca3690 Define a LH_LOAD_FACTOR constant and note the range that it can be set to. 
Change the resize check from "count > size" to "count >= size" to avoid a
potential infinite loop with high load factors and a full hash table.
