signal frame constructors and use it (on x86 and amd64) to fill in
the trap number in the signal context information.
Needed for wine which likes to look at the trap number...

signal frames. This commit looks worse than it is -- really just a
load of moving-code-around.
This is the first multiple-implementation module, in that it has a
single interface (pub_core_sigframe.h) but multiple implementations,
depending on the os-cpu pair. All the grotty details are hidden in
the implementation in m_sigframe/; callers need be aware only of the
interface. Yay.
