HPM Update

Made SQL and strlib functions HPM-friendly, special thanks to Yommy for bringing the issue up.
Added partial map.c support, for the all-handy map[] array, beware that soon the whole map.c renewal design will be commit and when that happens your usage of map.c functions in plugins might require some updates.
