Separate out C and html quoting into separate functions.
...
Dot sometimes wants normal C quotes, othertimes html. Quite annoying,
really, but this is cleaner anyway.

Don't draw arrows leaving return statements.
...
Return statements never flow to the next block (or any other block, for
that matter), so drawing arrows leaving them not only messes up dot's
graphs, but is quite missleading.

Output basic block flow diagrams to files.
...
The output can be controlled via --block-dot (not yet documented). The
files a named <sourcefile>.<function>.<stage>.dot. Currently, stage will be
one of "initial" (after expression to statement conversion), "thread"
(after jump threading), "dead" (after dead block removal), "final" (final
state before actual code emission).

...
The relative block number and the label user count are printed now.

Nuke the rcsid stuff.
...
It's pretty useless in git.

Bring back the unsigned type (PROGS version bump)
...
This is only low-level support (the unsigned keyword still does not work),
but sufficient to make switch statements using jump tables work.

Create and use alias operands for alias expressions.
...
This avoids the alias expression modifying the operand used in other
expressions.
