change mquery() function call signature to be the same a mmap(). It
needs the prot/flags info and passing the addresses via arg/return allows
it to be traced via ktrace better than an in/out paramter.
This adds a new mquery syscall and renames the old one to omquery.
New kernel _MUST_ be built and installed before building ld.so with this change.
