Subject: CLEANUP: hlua: rename hlua_appctx* appctx to luactx
X-Git-Tag: v2.4-dev18~16
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7e702d13f44a68cede269eb1ece34f93dadd2d6b;p=thirdparty%2Fhaproxy.git

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".
