Tidy the tlb flushing code. With tt mode gone, there is no reason to have the capability to have called directly from do_mmap, do_mprotect, and do_munmap, rather than calling a function pointer that it is given. There was a large amount of data that was passed from function to function, being used at the lowest level, without being changed. This stuff is now encapsulated in a structure which is initialized at the top layer and passed down. This simplifies the code, reduces the amount of code needed to pass the parameters around, and saves on stack space. A somewhat more subtle change is the meaning of the current operation index. It used to start at -1, being pre-incremented when adding an operation. It now starts at 0, being post-incremented, with associated adjustments of +/- 1 on comparisons. In addition, tlb.h contained a couple of declarations which had no users outside of tlb.c, so they could be moved or deleted.
