CLEANUP: hlua: rename hlua_appctx* appctx to luactx

There is some serious confusion in the lua interface code related to
sockets and services coming from the hlua_appctx structs being called
"appctx" everywhere, and where the real appctx is reached using
appctx->appctx. This part is a bit of a pain to debug so let's rename
all occurrences of this local variable to "luactx".
