read when the -t or -C switch is encountered and parts of it are processed.
The remaining parts are processed when all object files and libraries have
been read. To make this work, the expression evaluation in cfgexpr has been
rewritten to generate true expression trees. This means that expressions in
the linker config may use exports from the object files.
Separation of config file processing is the base for several enhancements, for
example forced imports by linker config.
This code needs more work and is only very, very, very roughly tested.

this is what it really is. Added a real EXPR_SECTION which is now used in
the linker to represent the run address of a segment, provided that it is
requested to be defined. Changed some named in use of EXPR_MEMAREA. Added
handling of the new EXPR_SEGMENT to both, the binary and o65 output format.
