Remove the deprecated functions such as getIntField in PVStructure,
whose usage has been replaced by that of the template getSubField
function and which are now no longer called anywhere.
For each getSubField overload a throwing getSubFieldT has been added and
vice versa. These have been documented in doxygen and in the module
documentation.

Implementation of getSubField (and getScalarArrayField) introduced in
the getAs pull request throws an exception then catches it to return a
null pointer. Implement without throwing.

Fix seg fault when getAs is called with a string of the form x.y (or
x_1. ... x_n.y) where x or (x1. ... .x_i) is not a structure field.
