Add a Lua wrapper library for openssl.
Add patches for:
1. Revise the makefile, so the package can be built under openwrt
2. Remove "lua_isinteger" implementation from the package's "compat"
code in order to avoid linkage issues - An implementation already
exists in the target's Lua package.
3. Support OPENSSL_NO_SSL3_METHOD & OPENSSL_NO_COMP
