Add support for generating method entries from stubs

[kocsismate]

Not yet finished. Hopefully the @mapping PHPDoc makes sense.

Shouldn't @mapping just reuse @alias?

[kocsismate]

So you mean that FuncInfo::alias should store the value coming from either @mapping or @alias?

My problem is that mappings and aliases won't be mapped to the same ZEND_RAW_FENTRY, since the class name is also stored for aliases (zim_##classname##_##alias), while not for mappings (zif_##func_nam). As far as I see, the only solution in this case would be to generate ZEND_RAW_FENTRYs - which is a no-go I think. But maybe do you know something else? Or did I misunderstand you?

@kocsismate What I mean is that (assuming we're on a method) @alias Foo::bar would end up being an MALIAS and @alias bar would end up being a MAPPING.

@nikic I see! I like this idea! I'll continue the PR later :)

Hopefully, my latest commit addresses all the comments. :)
