Counter-example: gcd 4 (4 mod 2) = gcd 4 0 = 4 <> 2 = gcd 4 2.

Note that the "divides" definition from the theory is overridden with a
notation, which happens to be equivalent.

Modify the Coq printer so that all the declarations (rather than just queries) are taken into account when updating a file.

It amounts to
- adding missing data in the file header,
- changing <font> to <span>,
- enclosing all the comments into <p> blocks.

Fix why3doc always generating incorrect links when outputting to a directory, which is the case for stdlibdoc.

Note that this is a short-term fix only, as it still uses Filename.basename
like the older code. As a consequence, it only works if the layout of the
generated files is flat.

Generating the documentation was not working since the symbols read by
why3doc in local files were not the ones that had been globalized from
installed files.

The original idea was to replace t1 by t2 only when t1 is more complicated
than t2, which was implemented by saying that t1 is neither a variable nor
a constant. Unfortunately, it means that no substitution happens when both
t1 and t2 are variables and/or constants. This patch fixes it.
