This commit adds the builtin types to the VM's builtin classes
buffer (however no methods were added to those classes) and a super
class parameter introduced while creating a new class.
this is a part of the class implementation. In this commit classes
and instances type were completely cleaned and prepared for a new
implementation. Native class registering mechanism were fully refactored
and made it much simpler.
a buffer of classes for primitive types added to PKVM, but they'll
not be initialized in this commit.
names buffer and constant pool of a module are now merged (just like
java's constant pool).
VM's core libraries and scirpt modules are merged into a single
map name modules.
creating a new module doesn't register it automatically anymore,
you need to call pkRegisterModule(...) each time.
newModule() function refactored with a simpler interface, we're not
setting path or registering globals anymore, the caller is
responsible for that.
now it's easier to re-use cli modules into another hosting
application and a little python script have added to generate
native api to support native extension library.
