configure_file: Add support for indented cmakedefine

Browse Source 
Optional spaces and/or tabs are now understood between the '#' character
and the 'cmakedefine'/'cmakedefine01' words. This indentation is
preserved in the output lines.

line after the variable name, if any, is processed as above.
Input file lines of the form ``#cmakedefine01 VAR`` will be replaced with
either ``#define VAR 1`` or ``#define VAR 0`` similarly.
The result lines (with the exception of the ``#undef`` comments) can be
indented using spaces and/or tabs between the ``#`` character
and the ``cmakedefine`` or ``cmakedefine01`` words. This whitespace
indentation will be preserved in the output lines::
# cmakedefine VAR
# cmakedefine01 VAR
will be replaced, if ``VAR`` is defined, with::
# define VAR
# define VAR 1
If the input file is modified the build system will re-run CMake to
re-configure the file and generate the build system again.

indented_cmakedefine
--------------------
* The :command:`configure_file` command learned to support indented
``# cmakedefine`` and ``# cmakedefine01``. Spaces and/or tabs between
the ``#`` character and the ``cmakedefine``/``cmakedefine01`` words
are now understood and preserved in the output.
