2d97630d03 Added somewhat more complex demo. It looks for emdrivers in the current directory and tries to load them until one loads successfully. In that case it "streams" its overlay files into extended memory. Finally it loads its overlays from extended memory (or disk) and calls into them.

942c0b6b2f Choose another way to fix the issue from r5804: When parsing the directory 
name, add a file mask, so the result is "$0:*" or similar. When specified like
this, the drive accepts the r/o specifier ",R" so we don't have to complicate
the code in open().

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.
