Commit Message

After the last big formatting patch a number of changes have been
commited that do not conform with our style/uncrustify config. This
has lead to the problem that running uncrustify on before sending PR
some of the changes made by uncrustify need to be backed out again.

To bring everything back to the agreed upon style, run uncrustify once
more. Uncrustify version used:

	Uncrustify-0.70.1_f

I double checked the result by running uncrustify (Uncrustify-0.69.0_f)
from Ubuntu focal/20.04 which does not do any further changes and
uncrustify 0.66.1_f from Ubuntu bionic/18.04, which only produces one
small change:

-gc_addspecial(void *addr, void(free_function)(void *), struct gc_arena *a)
+gc_addspecial(void *addr, void (free_function)(void *), struct gc_arena *a)

I therefore went with the variant produced by the newer versions of
uncrustify.

The version uncrustify 0.59 produced a lot of changes, many of which
were not changed by this commit, so that version is too old.

This looks wrong to me. we want a space between the return type and the
prototype name. no?

This is also non-expected - we always want spaces around binary bitwise
operators.
