safehasattr: pass attribute name as string instead of bytes This is a step toward replacing `util.safehasattr` usage with plain `hasattr`. The builtin function behave poorly in Python2 but this was fixed in Python3. These change are done one by one as they tend to have a small odd to trigger puzzling breackage.

debug: `isinstance(a, x) or isinstance(a, y)` is `isinstance(a, (x, y))`

debug: update usage strings of debugignore and debugnodemap Multiple files can be specified for debugignore. debugnodemap does not take a revision argument.

debug: slightly improve wording on the InputErrors from the previous patch

debug: use InputError instead of CommandError for validating arguments

clonebundle: add a `filter_bundle_url` function This function does nothing by default, but give extension the opportunity to alter the URL, typically, this could be used to inject authentication token when serving clone bundle for private repositories.

clonebundles: move the manifest reading in a dedicated function We are about to make the logic more advanced to help hosting solution, so we need to centralize it first.
