registrar: introduce new class for registration to replace funcregistrar
_funcregistrarbase differs from funcregistrar in points below:
- every code paths should use same class derived from
_funcregistrarbase to register functions in a same category
funcregistrar expects (3rd party) extensions to use (a class
derived from) delayregistrar.
- actual extra setup should be executed in another function
For example, marking revset predicate as "safe" is executed in a
class derived from _funcregistrarbase, but putting name of "safe"
predicate into safesymbols is executed in another function for it.
funcregistrar expects derived classes to do so.
New class is named as module private one, because code paths, which
register functions, should use not it directly but one derived from
it.
