i387: Split up <asm/i387.h> into exported and internal interfaces
While various modules include <asm/i387.h> to get access to things we actually *intend* for them to use, most of that header file was really pretty low-level internal stuff that we really don't want to expose to others. So split the header file into two: the small exported interfaces remain in <asm/i387.h>, while the internal definitions that are only used by core architecture code are now in <asm/fpu-internal.h>. The guiding principle for this was to expose functions that we export to modules, and leave them in <asm/i387.h>, while stuff that is used by task switching or was marked GPL-only is in <asm/fpu-internal.h>. The fpu-internal.h file could be further split up too, especially since arch/x86/kvm/ uses some of the remaining stuff for its module. But that kvm usage should probably be abstracted out a bit, and at least now the internal FPU accessor functions are much more contained. Even if it isn't perhaps as contained as it _could_ be.
