src/: Remove g_ prefixes and _g suffixes from variables

These were often used to distinguish CAR_GLOBAL variables that weren't
directly usable. Since we're getting rid of this special case, also get
rid of the marker.

This change was created using coccinelle and the following script:
	@match@
	type T;
	identifier old =~ "^(g_.*|.*_g)$";
	@@
	old

	@script:python global_marker@
	old << match.old;
	new;
	@@
	new = old
	if old[0:2] == "g_":
	  new = new[2:]

	if new[-2:] == "_g":
	  new = new[:-2]

	coccinelle.new = new

	@@
	identifier match.old, global_marker.new;
	@@
	- old
	+ new

	@@
	type T;
	identifier match.old, global_marker.new;
	@@
	- T old;
	+ T new;

	@@
	type T;
	identifier match.old, global_marker.new;
	@@
	- T old
	+ T new
	 = ...;

There were some manual fixups: Some code still uses the global/local
variable naming scheme, so keep g_* there, and some variable names
weren't completely rewritten.
