Now global lock uses the actual global lock. Currenly if no lock
can be acquired, we just panic the kernel so that I remember to
implement it properly once AML is running concurrently.

Kernel: Implement barebones AML parser
...
This implements only parsing for AML in qemu. InvokeMethods are not
parsed since number of arguments to Methods is not yet known.
Parsing AML uses multiple kilobytes of stack space, so I increased
boot stack size by a lot :D
I am not sure where my own AML is going, but this is good start if
I decide to implement full ACPI on my own.
This code is very much just ugly macro expansion.
Qemu has 2 DefPackage elements that I am not able to parse. Package
data ends while there should be still multiple elements.
