Templates are now directly in dune's sexp language. The syntax is change to %{}
from ${} and $(). Old templates are still supported in jbuild files.
Other changes in this PR:
* Removal of ! patterns in variables
* Strict expansion for templates in dune files. Missing vars are now an error
* Using the correct syntax to parse included files in dune
* Improvements to the tests
* Syntax aware pretty printing of sexps. Now you must pass Dune vs. Jbuild to
print sexps

The syntax controls validation that will be used to make sure we are printing
something/reading valid

Things like \a are no longer allowed. Before they would be interpreted
as a literal \a. This will allow to introduce new escape sequences in
the future if needed.

They are almost never used and they complicate the language. The
parsing of jbuild files in unchanged.

Replace the current generated parser by an ocamllex lexer + a simple
parser.
The new code is:
- much simpler and smaller
- shouldn't cause ocamlopt to stack overflow anymore on BSD systems
- slightly slower but not that much
