Message:

Merge unified panic architecture (Phase 1).

Note that this is still work in progress as there are the following sharp edges:

• imprecise detection of read/write accesses on some architectures
• missing or imperfect capability to print stack traces on some architectures
• istate_t on some architectures may contain too little valuable information
• basically all trap frames need to be reorganized to look like a normal stack frame on the stack trace so that there are no missing frames
• panic_common() could print more information about the current context such as the task name, thread name, ASID etc.
• functions that call panic_*() should be protected against inlining to avoid missing or confusing stack frames in the stack trace
