Rationale: don't spam the user with warnings he can do nothing about.  He will
still get warnings when he uses the ConfigParser in is his own programs, and
we (as developers) will have to remove configparser.cc the same instant we
remove configparser.hh anyway.

Merged from trunk@6356.

Use parametertree.hh to keep hierarchical string-based data, 
and parametertreeparser.hh to read such data from files and streams.

This code used to be in ConfigParser, which I will deprecate in a second.
The new implementation is inspired by boost: each parser is a global method
in a namespace.  In our case, that namespace is a class ParameterTreeParser,
because it needs to have some private methods (ltrim and rtrim, to be
precise).  On demand, parsers for more formats can be added to this class/file.

I do not insist on any of the details of this new code. However, I wanted
to have the many architectural change before the creation of the 2.2 release
branch.

This is especially useful when an array is needed to initialize a class
member.

This uses a statement like

  array<T, 2> result = { t0, t1 };

to initialize the array.  This is correct and explicitly allowed by the
upcoming standard.  Unfortunately g++ warns about this with -Wmissing-braces
(which is implied by -Wall) because this relies on brace elision.  The report
<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25137> has been filed more than
five years ago, but so far not much has happened.
