Better identifier parsing

  * '(<|>)' and '`elem`' now get parsed and rendered properly as links
  * 'DbModule'/'DbUnitId' now properly get split apart into two links
  * tuple names now get parsed properly
  * some more small niceties...

The identifier parsing code is more precise and more efficient (although to be
fair: it is also longer and in its own module). On the rendering side, we need
to pipe through information about backticks/parens/neither all the way through
from renaming to the backends.

In terms of impact: a total of 35 modules in the entirety of the bootlib + ghc
lib docs change. The only "regression" is things like '\0'. These should be
changed to @\\0@ (the path by which this previously worked seems accidental).
