[PATCH] sigcontext_struct -> sigcontext

Hi Paul, Anton, Jeff,

PPC and PPC64 are the only two architectures that define a struct
sigcontext_struct - all the others use struct sigcontext (UML seems to
have been infected :-)). This patch just renames sigcontext_struct to
sigcontext. It also renames sigcontext32_struct to sigcontext.

Cheers,
