[PATCH] powerpc: Merge signal.h

Browse Source 
Having already merged the ppc and ppc64 versions of signal.c, this
patch finishes the job by merging signal.h.  The two versions were
almost identical already.  Notable changes:
	- We use BITS_PER_LONG to correctly size sigset_t
	- Remove some uneeded #includes and struct forward
declarations.  This does mean adding an include to signal_32.c which
relied on the indirect inclusion of sigcontext.h
	- As the ppc64 version, the merged signal.h has prototypes for
do_signal() and do_signal32().  Thus remove extra prototypes from
ppc_ksyms.c which had them directly.

Built and booted on POWER5 LPAR (ARCH=ppc64 and ARCH=powerpc).  Built
for 32-bit powermac (ARCH=ppc and ARCH=powerpc) and Walnut (ARCH=ppc).
