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
Theora.

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

This is an alternative to SDP to convey the codec configuration
necessary to decode the stream. The configuration is sent only once at
the beginning of the stream; at least you won't be tempted to waste
bandwidth with retransmissions. This is a ad-hoc hack, but it's not too
bad or pervasive.

If the the link is relative, psz_uri is dynamically allocated a string of the
absolute URI (which is also returned by the function).   However, if it isn't,
NULL is returned and nothing is allocated.   segment_New performs a strdup, so
the pointer is not saved.   Thus, check if the allocation occurred and clean up
if needed.

The defined HAVE_AVCODEC_MT is used by modules/codec/avcodec/avcodec.c
and modules/codec/avcodec/video.c. It was only defined in modules/codec/avcodec/video.c.

This patch moves the define to modules/codec/avcodec/avcodec.h.

Take into account that HLS streams with bandwidth specified are not in ascending
(or descending) order. Choose really the best wrt to measurements.
