stand: Create common/modinfo.h Move all the MOD_xxx macros to this header. Each user of this interface is currently required to define MOD_ALIGNMENT(l). modinfo was selected because it sits inbetween modules and metadata and will make it easier to migrate to new, shared intefaces.

stand: update prototypes for md_load and md_load64 These are declared as extern in a number of files (some with the wrong return type). Centralize this in modinfo.h and remove a few extra stray declarations as well that are no longer used. No functional change. Note: I've not tried to cope with the bi_load() functions which are the same logical thing. These will be handled separately.

stand: Move md_copymodules into modinfo.c and reduce copies md_copymodules, bi_copymdoules, bi_copymodules32 (x2) and bi_copymodules64 (x2) are all the same routine... Replace them all with md_copymodules. This saves about 800 bytes on i386 BIOS loader, which is a nice bonus.

stand: collapse all copies of *copyenv into md_copyenv Use the efi's bi_copyenv to md_copyenv and place it in modinfo.c. Remove all other nearly identical and efi's has the best error handling.
