manuals: Spellcheck and capitalization fixes

- Spelling fixes found using Emacs' spelling checker
  configured for US English
- Fixes for some capitalization issues, especially some
  project names (QEMU, openSUSE, BusyBox), that were not
  consistently used with the same capitalization anyway.
- A few whitespace fixes too
