[Scummvm-devel] Merging remaining GSoC branches (Attention PORTERS!)

Last time I checked the branch was working as far as loading engine plugins
in during runtime and running correctly on DS and PS2. However, the only
approach implemented thus far for loading one plugin at a time is the
"iterate through each plugin, loading then checking if it fits the desired
game then unloading, until you find the right one" and with the current
implementation there's memory fragmentation after each unload (so successive
plugins are loaded further and further in memory). Obviously this is counter
to the point of having dynamic plugins on platforms like the DS. I've been
meaning to look into this (the idea being to make sure whatever is getting
allocated in memory after a plugin load gets loaded before the plugin
instead) but unfortunately won't have time due to a terribly packed school
schedule (multiple projects/essays/problem sets, etc) until Wednesday night
next week. :-(
