9e5b8d99a3 Fix MSVC build broken by #1058 
MSVC complains about unary negation of unsigned, but it's
intended.  Suppress the warning.

https://github.com/cc65/cc65/pull/1058#discussion_r451757967

"Tested" with godbolt.org.

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

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.

83e0c70de5 Replace GIT_SHA with a more versatile BUILD_ID definition. 
When compiling cc65, it will by default place the git hash (if available) of
the checked out commit in the version string.  This isn't useful when building
a package for a Linux distribution, since there either won't be an upstream
git hash if there is one at all.

Thus we replace GIT_SHA with a more versatile BUILD_ID, which can be defined
to any arbitrary string.  When building, its contents will be appended to the
version string instead of the git hash.

If BUILD_ID is not defined by the user the behaviour will be exactly the same
as before.  That means BUILD_ID gets automatically defined to Git <GIT_SHA>,
if it can be determined from a checkout.
