7ebaec1802 Don't save and restore the zero page locations used. 
Saves 19 bytes code (in the exe file) and reduces memory footprint
of the program by 45 bytes (code & bss).

to ROM NMI handler.

5ed1fac0d6 Use unique variables for cc65 toolchain. 
Originally I used the usual variables (like $(CC) and $(CFLAGS) ) but after
all this doesn't make sense as any predefined values and/or user defined
settings can only be wrong.

619b215260 Added library reference em_libref to EMD interface. 
Occasionally dynamically drivers suffer from not being to refer to
content in the C library. Therefore I added a mechanism to allow
a C library for a certian target to define a symbol that will be
handed over to dynamic drivers for that target. Then the drivers
can use their refernce to that symbol to access content in the C
library.

56b6dcf814 Brought back mouse driver source code. 
The mouse driver source code in question was removed two years
ago with commit 6cbbe66c87.
It seems however desirable to have it around visible in the source
code tree for reference purposes.

2e8a65bda4 Renamed Atari drivers.

- no longer than 7 characters
- with a common prefix
