0390c34e88 Changed multi-line C comments into another style. 
The left side doesn't look unbalanced.

2c975d3642 Create static drivers directly from source files. 
Up to now static drivers were created via co65 from dynamic drivers. However there was an issue with that approach:

The dynamic drivers are "o65 simple files" which obligates that they start with the 'code' segment. However dynamic drivers need to start with the module header - which is written to. For dynamic drivers this isn't more than a conceptual issue because they are always contain a 'data' segment and may therefore only be loaded into writable memory.

However when dynamic drivers are converted to static drivers using co65 then that issue becomes a real problem as then the 'code' segment may end up in non-writable memory - and thus writing to the module header fails.

Instead of changing the way dynamic drivers work I opted to rather make static driver creation totally independent from dynamic drivers. This allows to place the module header in the 'data' segment (see 'module.mac').

d6c3bd29ac Renamed JUMPTABLE and cleaned up module.cfg. 
This change was suppsed to fix the issue that the former JUMPTABLE is merked as 'ro' while it is actually written to in several scenarios. When drivers are converted using co65 and then compiled into ROMs the JUMPTABLE isn't copied to RAM and therefore the write operations in question fail.

However unfortunately I didn't succeed in changing that :-( Just setting the former JUMPTABLE to 'rw' broke the drivers. So I placed the DATA segment directly after the former JUMPTABLE segment. This made the drivers converted with co65 work again - obviously after changing libsrc/Makefile:235 from '--code-label' to '--data-label'. But the actual dynamic drivers still didn't work as the former JUMPTABLE wasn't placed as the beginning of the loaded file anymore. That effect could be changed by exchanging src/ld65/o65.c:1391 with src/ld65/o65.c:1394 but doing so broke the drivers again :-((

3f0af9b241 Have src/Makefile and libsrc/Make use disjoint work directories. 
Building the clean target in src or libsrc should only delete stuff created by the make in those directories. Having both separated allows the Travis CI build to replace the native binaries with cross built binaries while keeping everything else.

44ccb27549 Changed Makefile.inc handling. 
It seems more appropriate to trigger the inclusion of Makefile.inc via $TARGET (instead of $SRCDIR). This is btw. more consistent with extzp.s inclusion which is triggered via $TARGET too.

b477023783 Turn off mouse polling interrupt if the mouse hasn't been moved for 
some time. Turn it back on when the mouse is moved again.
Since the polling interrupt runs at a rather high frequency (1kHz),
this saves many processor cycles when the mouse is inactive.
