David Young 2f09d8f3c8 Move the GNU warnings configuration under config/gnu-warnings/ and trim
the filename prefixes.  Update config/gnu-flags to suit.

I also made changes to config/cmake/HDFCompilerFlags.cmake, but I'm not
sure they're correct.

# In GCC 4.4.7, the compiler gripes about shadowed global
# declarations when a local variable uses the name of a
# function that's in a system header file. For some reason,
# later versions of GCC (e.g., 5.2.0) don't complain about
# the shadowed globals. Maybe later versions are less fussy?
# Anyway, the shadowing seems to be harmless, and GCC 4.4.7
# is not a supported compiler, so let us promote shadowed globals
# warnings to errors only for GCC 5 and later.
