a25b28a972 Added files to the pet library that support the overlay demo sample program. 
cbm_load() is needed because the Pet/CBM Kernals don't have a LOAD function that can be used by machine code programs.

81550ca1ee CS_MergeLabels: Keep labels referenced by data 
Partial fix for ICE in #1211.  This may fix enough to allow #1049 to be
fixed.

When merging labels, keep the first label with a ref that has no JumpTo;
this is a data segment label, used by computed gotos.

The real fix is to track and rewrite labels in data, but this is more
involved.

fd208fdf0b - Added support for calling subdir Makefiles for the make targets 'samples' and 'clean'. 
- Adjusted the 'tutorial' Makefile to actually work as expected.

Note: The 'disasm' and 'geos' Makefiles don't seem to work so they are not called as of now.

b931e65811 Fix ICE for bit-fields with typedef 
Fixes #1267

Avoid ICE, but treat plain int bit-fields declared via typedef as
signed rather than unsigned.  It is more efficient to treat them
as unsigned, but this requires distinguishing int from signed int,
and this is curently not done.

d0089aef95 Fix bit-field truncation warning message 
Fix copy & paste bug with warning message.

struct X {
      signed int a : 3;
};
struct X g = { 5 };

Before:
s.c(4): Warning: Implicit truncation from 'int' to 'int : 3' in bit-field
initializer changes value from 5 to 5

After:
s.c(4): Warning: Implicit truncation from 'int' to 'int : 3' in bit-field
initializer changes value from 5 to -3

Fixes #1268

81ac28ff71 Used TAY/TYA instead of PHA/PLA when extracting a bit-field. 
Without optimization, it saves a few CPU cycles.  With optimization, it saves more cycles and a few bytes.

ea95728330 Avoided an avalanche of messages from bad bit-field declarations. 
Made cc65 replace a bad bit-field type with a good one, and always parse the field width.

Shortenned a parameter name to a spelling that's consistent with other function headers.
