Various manual fix-ups:
- Use "heap blocks" rather than "malloc'd blocks" as heap blocks covers
  calloc, realloc, new, new[], memalign, etc.

- Used "GDB" and "GCC" throughout rather than "gcc" and "gdb".

- Made various tag uses more consistent.

- Greatly clarified the instructions on --xml=yes and its friends.

- Lots of other little improvements and fixes to out-of-date things and
  Linux-centric things, mostly in Section 2.
