remotefilelog: adjust the signature of basepack.createindex pytype point that the subclass signature have been updated.

pytype: add the couple annotations for pytype to understands the lrunode After loosing 2d6 SAN, I eventually understood that pytype was confused by method return type. Pytype is now happy.

pytype: ignore some signature mismatch in registrar pytype is grumpy about a sub method having a different signature than the one we use here. pytype error: internalmerge: Overriding method signature mismatch [signature-mismatch] Base signature: 'def _funcregistrarbase._extrasetup(self, name, func) -> Any'. Subclass signature: 'def internalmerge._extrasetup(self, name, func, mergetype, onfailure = None, precheck = None, binary = False, symlink = False) -> Any'. Parameter 'mergetype' must have a default value.

hgweb: update _runwsgi try/except range to be valid The `tmpl` variable is used in the `except` and `finally`, so we need it created before the `try` is open.

pytype: add type information for `annotateresult.lines` This seems to appease a confused pytype.

pytype: ignore attribute error for time.clock This seems to be a Windows only attribute.

pytype: ignore certifi import error This is an optional import so we should not complains about it.

pytype: ignore some signature mismatch in configitems pytype is grumpy about the dict.update having a more complex signature than the one we use here. pytype error: itemregister: Overriding method signature mismatch [signature-mismatch] Base signature: 'def builtins.dict.update(self) -> None'. Subclass signature: 'def itemregister.update(self, other) -> Any'. Parameter 'other' must have a default value.

pytype: only output the "pytype crashed" message on error If pytype did not crash while generating stub, that message is kind of confusing. It seems simple enough to avoid it in this case.

pytype: drop the now useless assert As the imported types are now used by type annotation, these ugly assert are no longer needed.
