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.

+# For GCC 8, promote maybe-initialized warnings to an error. GCC 8
+# reports 0 maybe-uninitialized warnings where earlier versions
+# make many false reports. GCC 8 seems to analyze calls to static
+# in order to detect initializations that occur there. It's possible
+# that GCC 8 only performs that analysis at -O3, though.
