[XTENSA] Remove non-rt signal handling
The non-rt signal handling was never really used, so we don't break anything. This patch also cleans up the signal stack-frame to make it independent from the processor configuration. It also improves the method used for controlling single-stepping. We now save and restore the 'icountlevel' register that controls single stepping and set or clear the saved state to enable or disable it. Signed-off-by: Chris Zankel <chris@zankel.net>
