xcbXorg is a connection manager lib that'll be used in common by all of
the xcb API frontends: xcbMouse, xcbWindow and xcbKeyboard. We moved
it into commonLibs to make it make more sense.
We also cleaned up the M4 scripting around AC_ARG_VAR-ing new common
libs as well as sense/wilzor libs.
* We had a prior issue where EQUALS would require that there be no
whitespace between itself and its operands on either side. We got
a bad solution from ChatGPT 4o. We got a proper solution now from
o1.
* Previously, if a string ended with a backslash right before EOF, the
backslash would be included. Now it will be dropped.
* Merge the two regexes for ignoring whitespace into one.
We add 2 new threads for handling the interoceptors and extrospector
events. Also add comments explaining the purpose and role of each of
these major threads.
