Fix library-related indirection bug

Accessing library functions via function pointer seems to cause a reset.
Still investigating the cause.

- compile keymaps subdir as part of main src cmakefile, rather than as a
separate library.

- rather than setup table of function pointers and using an indirection
in the main code, set up a jump table (switch).  This is cleaner.
