Rename lh_xxx,sk_xxx tp OPENSSL_{LH,SK}_xxx Rename sk_xxx to OPENSSL_sk_xxx and _STACK to OPENSSL_STACK Rename lh_xxx API to OPENSSL_LH_xxx and LHASH_NODE to OPENSSL_LH_NODE Make lhash stuff opaque. Use typedefs for function pointers; makes the code simpler. Remove CHECKED_xxx macros. Add documentation; remove old X509-oriented doc. Add API-compat names for entire old API Reviewed-by: Dr. Stephen Henson <steve@openssl.org>

Add a lock around the OBJ_NAME table Various initialization functions modify this table, which can cause heap corruption in the absence of external synchronization. Some stats are modified from OPENSSL_LH_retrieve, where callers aren't expecting to have to take out an exclusive lock. Switch to using atomic operations for those stats.
