Lua pcre inside nginx

NginX hooked pcre memory alloc/free functions pcre_malloc/free to use
its memory pool, in order to work around its memory leaking problem. As
a side effect, it reset this pool to NULL after every usage in core
without considering possible external references. If you don't set pcre
memory hooks to your own implementation, you will surely get the error.
ngx_lua has fixed this problem, and can use pcre related extensions
normally after v0.1.6rc5.
* src/core/ngx_regex.c in NginX sources
* ngx_http_lua_patch.c in ngx_lua sources
