build: i18n-scan.pl: use xgettext to extract message strings

Using xgettext has a few benefits compared to the previous perl extraction
approach. The xgettext utility is able to properly distinguish commented
from uncommented code and it is able handle concatenated constant
expressions such as `_("Some " + "string")`.

A further benefit is the ability to extract translations with disambiguation
contexts and plural translation calls.

luci-base: luci.js: further nested Class.super() call fixes

Use stacks keyed by class id + symbol internally to not clobber the
prototype scope pointer when repeatedly calling super() in invoked
methods.

luci-base: luci.js: properly handle nested Class.super() calls

Introduce a unique __id__ attribute per class and use that, together with
the symbol name being looked up to, to form a unique key which is used to
store the prototype scope pointer.

This fixes cases where a call to super() invokes a procedure which is
calling super() as well on a different class or symbol.
