build: update default CXXFLAGS.

* Add -std=c++03 and -pedantic, and fix the resulting warnings. The
  long-long-int warning is explicitly suppressed because it's not
  trivial to workaround in a platform-independent and ISO-conformant
  way without using C++11.

* Initial support for building with -std=c++11 (experimental).

* Prefer -Og optimization level in debug builds if supported by the
  compiler.
