/* Inlined replacements for INDEXENT/ENTINDEX
 * It only really removes the overhead of the push/jump
 * but since INDEXENT/ENTINDEX are used a lot with amxx
 * it might be beneficial to include.
 * NOTE: Bad stuff will happen if you call these before
 *       NEW_Initialize()
 * NOTE: No bounds checking is done because natives
 *       should use their own bounds checking!
