pkVar is removed and slots (like wren) are implemented for accessing or passing pocketlang values to C and vice versa. Yet all the slot related functions are callable at runtime (a fiber is associated with the VM) which needs to be refactored to allocate slots even if it's not runtime, to let users make use of the pocketlang values before or without running a function.
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.
