data is a pointer to user-supplied data used for evaluating the expression. It should not be modified by the evaluation. Note that this modifies the flesh API to the (undocumented) thorn-visible function Util_ExpressionEvaluate.

Expression are of the form:
foo::bar = 2*sin(foo:baz)
ie. arithmetic and access to already set parameters. The new behaviour is
triggered if the parameter string (for real, boolean and int parameters) does
not parser properly as a double/int/bool. This last test is mostly an
optimization.
The largest change is actually in the expression parser which has been extended
to handle eg. exponential notation and negations. It now uses a state machine
to parse its input.

Some extra checking.
Moved types not needed by external stuff into its own header.

Now can deal with both floating point and integer values.
You can use the functions from the standard C maths library which take
one argument.
Evaluation should be faster, 'though parsing is probably a bit slower.
Now the user-supplied evaluation routine is called just once at the
beginning of the evaluation, so if any of the evaluations need a global
operation, these can all be done at once.
The routines have now been renamed as Util_ functions and the
header file cctki_Expression.h has been renamed as util_Expression.h.
IMPORTANT NOTE:
The above means you will need to
rm configs/*/build/Cactus/util/Expression.c.d
rm configs/*/build/Cactus/main/Groups.c.d
after updating to get rid of stale dependency files.

Currently just a copy of the stuff from HTTPD changed to integer and a
bug fix. When it is generalised and some optimisation is done these will
become Util routines rather than CCTKi routines.
