9858e47dfd Pad bit-fields only to the next byte 
Fixes #1054.

Previously, bit-fields followed by another field were aligned
to two bytes.  Bit-fields ending the struct were (and continue
to be) aligned only to a single byte.

```
struct s {
  unsigned int x : 4;
};

struct t {
  unsigned int x : 4;
  unsigned int y;
};
```

Before: `sizeof(struct s) == 1`, sizeof(struct t) == 4`
After: `sizeof(struct s) == 1` sizeof(struct t) == 3`

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
