Side discussion: It's a bit odd to see common-types.h and then see
errors.h spelled as errors.h and not common-errors.h.
[Or vice versa.]

Is consistency in the file names a goal?
I realize common-utils.h needs to be something other than utils.h
because gdb and gdbserver each still have their own.
And similarly for common-defs.h - gdb still has defs.h.
But nothing else in common/ is spelled common-foo,
and I wonder if less randomness would be useful.
I'd be happy with #include "common/errors.h", and so on.
That way when I see it used I know where to look without having to
rely on memory or ls.

Nit, and I do mean nit :-): errors.h uses COMMON_ERRORS_H,
so should this be COMMON_COMMON_TYPES_H?
