[PATCH/RFC] Register sets

[Mark Kettenis <kettenis at chello dot nl>]

OK folks, after reading all reactions on my origional post I'm pretty
confident that the following definition of `struct regset' is what we
need:

/* Data structure describing a register set.  */

struct regset
{
  /* Data pointer for private use by the methods below, presumably
     providing some sort of description of the register set.  */
  const void *descr;

  /* Function supplying a register set to a register cache.  */
  void (*supply_regset) (const struct regset *regset,
                         struct regcache *regcache,
			 int regnum, const void *regs, size_t len);
};

It keeps in line with GDB's current object model, and provides a hook
to store any register set-specific data.  I've included only the
supply_regset call right now.  The read_regset will follow when I get
at implementing the gcore support.

It's my intent to check this in on Thursday or Friday, such that I can
make some progress with the corefile support over the weekend.
