2014-04-02remove struct elem entirely from hsearch.csin1-29/+22
There are two changes here, both of which make sense to be done in a single patch: - Remove hash from struct elem and compute it at runtime wherever necessary. - Eliminate struct elem and use ENTRY directly. As a result we cut down on the memory usage as each element in the hash table now contains only an ENTRY not an ENTRY + size_t for the hash. The downside is that the hash needs to be computed at runtime.
2014-04-02implement hcreate_r, hdestroy_r and hsearch_rsin1-30/+73
the size and alignment of struct hsearch_data are matched to the glibc definition for binary compatibility. the members of the structure do not match, which should not be a problem as long as applications correctly treat the structure as opaque. unlike the glibc implementation, this version of hcreate_r does not require the caller to zero-fill the structure before use.
