de7ea4e414 Implement PTRACE_GETSIGINFO. This makes Linux strace(1) quieter 
in some cases (strace -f man id > /dev/null).

060d0b57b8 Fix handling of r10 in Linux ptrace(2). This fixes decoding 
of the 'flags' argument to mmap(2) with Linux strace(1).

faf2fa21d7 Support PTRACE_GETREGSET w/ NT_PRSTATUS in Linux ptrace(2). 
While Linux strace(1) doesn't strictly require it - it has a fallback
to PTRACE_GETREGS - it's a newer interface, so we better support it
before the old one is deprecated.

132f90c660 Linuxolator whitespace cleanup 
A version of each of the MD files by necessity exists for each CPU
architecture supported by the Linuxolator.  Clean these up so that new
architectures do not inherit whitespace issues.

Clean up shared Linuxolator files while here.

but it allows to use 64 bit linux strace(1) on 64 bit linux binaries.
