Log Message:
Fix a signal handler bug originally reported by Hugh Graham some year ago:
If two signals are sent after each other without the process being run in
userspace between them then the second one will overwrite part of the signal
info stored on the userstack.
Fixed by rewriting and simplifying both the signal delivery code and the
trampoline code. Also bump signal version number to 2.
Rename __sigtramp1.S to __sigtramp.S.
