17c5504129 In Atari XEX output format, join memory areas if possible. 
This makes executables shorter if two memory areas are consecutive.

a00611798d Output bit-field data as chars instead of ints 
This prepares for #1058, which will pad bit-fields only to
the next byte, instead of the next sizeof(int) (two bytes).

OutputBitFieldData now outputs chars instead of ints, and
calls to this function loop until there is less than one byte
to output.  A final partial byte is written out with zero padding
as a final partial int was previously.

Allow overlap of bit-field storage units (#1055) 
* Allow overlap of bit-field storage units

Previously,
struct s {
    unsigned int x : 10;
    unsigned int y : 10;
};
had sizeof(struct s) == 4.

With this change, allow the storage units of x and y to overlap,
so sizeof(struct s) == 3, with y stored immediately after x,
with no padding between them.

An int bit-field (the only type currently supported) will still
never occupy more than two bytes.

* ParseStructInit: Fix typo and expand comment

Explain why there are at most 30, not 32 bits.

* ParseStructDecl: Rewrite AddBitFieldCall

No behavior change.

555282497c Removed --lib option from cl65. 
The general approach of cl65 when generating the command lines to be executed is to first put options and the put files. However, this doesn't work well with the --lib option which would rather need to be put when libraries in general are put. I opted to not add this special behavior to cl65 as
* the use case for the --lib option is _VERY_ specific
* cl65 is after all a wrapper for ordinary use cases

fb0d09a277 Changed sim65's internal error codes from 9-bit values to 7-bit values. 
Some shells truncate process return codes to 8 bits.  And, the eigth bit often is used to show that a signal stopped the process.

a0db846a97 Allowed old-style (K and R) function declarations to be fastcall. 
That lets them match old-style definitions.  It avoids "Type conflict" error messages.  It allows shorter function calls.

Fixed the types of some variables in "test/ref/otccex.c".  It avoids crashes on 64-bit Windows (32-bit Windows with 64-bit pointers).
