Parental advisory: naked kludge and explicit hack

We have reliable error detection with XCB, so this option has become
mostly useless. For testing/debugging, the developer can hack the
CheckSHM() function to return false if really needed.

This made no sense. If the thread is detached, the handle is released
asynchronously when the thread exits. So it cannot be used in any way
(except from the thread itself).

Note that Carbon code isn't supported in 64bit applications...

lua_variables: luaL_optstring returned pointer is valid as long as the value stay on the lua stack (also avoid an strdup).

Theora support is enabled. An option is added to manually select the
payload format of unknown dynamic payload types, in pre-arranged
streaming setups, without needing SDP. The only choice for now is

lua_variables: the pointers returned by luaL_checkstring might be invalid when the value is poped from the lua stack.
