30d3f201efd974e92af39ab7522ca30ddb2a379a Add a callback for `__has_include` and use it for dependency scanning.
This adds a preprocessor callback for the `__has_include` and
`__has_include_next` directives.
Successful checking for the presence of a header should add it to the list of
header dependencies so this overrides the callback in the dependency scanner.
Patch by Pete Cooper with some additions by me.
