Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

- * Unwind the current stack frame and store the new register values in the
- * structure passed as argument. Unwinding is equivalent to a function return,
- * hence the new PC value rather than LR should be used for backtrace.
- *
- * With framepointer enabled, a simple function prologue looks like this:
- *	mov	ip, sp
- *	stmdb	sp!, {fp, ip, lr, pc}
- *	sub	fp, ip, #4
- *
- * A simple function epilogue looks like this:
- *	ldm	sp, {fp, sp, pc}
- *
- * Note that with framepointer enabled, even the leaf functions have the same
- * prologue and epilogue, therefore we can ignore the LR value in this case.
