975a06c2ee Rewrote tgi_load_driver in assembler and fixed a possible memory leak when 
doing so. Changed the behaviour in case a driver is already loaded: Since the
library cannot know if this driver was linked statically or loaded
dynamically, an already installed driver is considered an error. It must be
removed before calling tgi_load_driver.

a4b6b6004a Removed tgi_load() and all corresponding infrastructure. The idea behind tgi_load() was to be able to describe a TGI mode in a target-neutral way by resolution and colordepth. However it turned out that there arn't any cc65 targets sharing any resolution. As a result the only working target-independent approach for a TGI program is to call tgi_loaddriver(tgi_stddrv); and then look up the resolution provided - and to adapt to that resolution.

e9f69ad123 Factored out generic LINE implementation based on SETPIXEL from the three drivers previously containing the identical code. 
Note: Originally I planned to create a module to be linked to the driver. However this turned out to cause quite some issues with the Makefiles - especially on the Apple2 where one driver uses to generic LINE implementation and the other doesn't. The final Makefile was so ugly that I rather opted for including the code in question on source level. In order to avoid to unwanted cross dependencies the whole .inc file content is wrapped in its own scope.
