This commit contains a couple large, interdependent changes: - In preparation for capability checking, the _syscall_verify_* functions now load most handles passed in, and verify that they exist and are of the correct type. Lists and out-handles are not converted to objects. - Also in preparation for capability checking, the internal representation of handles has changed. j6_handle_t is now 32 bits, and a new j6_cap_t (also 32 bits) is added. Handles of a process are now a util::map<j6_handle_t, handle> where handle is a new struct containing the id, capabilities, and object pointer. - The kernel object definition DSL gained a few changes to support auto generating the handle -> object conversion in the _syscall_verify_* functions, mostly knowing the object type, and an optional "cname" attribute on objects where their names differ from C++ code. (Specifically vma/vm_area) - Kernel object code and other code under kernel/objects is now in a new obj:: namespace, because fuck you <cstdlib> for putting "system" in the global namespace. Why even have that header then? - Kernel object types constructed with the construct_handle helper now have a creation_caps static member to declare what capabilities a newly created object's handle should have.
