(bug 43451) Restore old behavior of 'mod', add 'fmod'
...
In trying to fix bug 35866, I32c9eca6 changed the behavior of 'mod' to
no longer cast its arguments to integers, which conventiently also
solved bug 6068. However, this also broke many existing uses that
depended on that casting.
This change reverts 'mod' to its old behavior while still solving bug
35866, and at the same time adds a new 'fmod' operator with the new
behavior to keep bug 6068 fixed as well.

(Bug 35866) ParserFunctions: Division by zero in Expr.php
...
The PHP modulo operator ('%') casts its operands to ints, causing
floating point values 0 < $right < 1 to raise a divide-by-zero error.
Explicitly casting both operands to float and using fnmod() resolves the
issue. This change also tidies up the check for zero values and adds
tests.

Reimplement, but better! Use BC Math library where possible, for fixed-point math operations. The tolerance aspect has been included by doing math internally at 16 digits, but discarding the last two digits for the purpose of comparison.

Where applied, it assumes that any floating point number that is an integer to within one part in 10^10 should be replaced with that integer.

* Strip comments early, before template expansion. This mimics the behaviour in the old parser. Added parser tests demonstrating the regression this fixes. The syntactic effect is fairly elegant, with comments taking effect at source level, as expected. The removeHTMLcomments() and preprocessToDom() passes could be merged at a later date.
...
* No need for comment stripping in Expr.php anymore
* Updated srvus() to roughly account for these changes
* Gave comment handling its own preprocessor tag, and split off comment handling from extensionSubstitution(). This only applies for the non-HTML modes, since in HTML mode, comments are stripped early.
* Strip comments from template argument names (PPFrame::newChild).
