Portability fixes

- CFLAG gnu99 was changed to c99.
- CXXFLAG c++98 was changed to c++11.
- CFLAG -pedantic-errors was added so that non-ISO C now throws errors.
- _XOPEN_SOURCE feature test macro added and set to 600 to expose SUSv3
  and c99 definitions in modules that required them.
- Fixed tests (and bootstrap daemon logging) that were failing due to
  the altered build flags.
- Avoid string suffix misinterpretation; explicit narrowing conversion.
- Misc. additions to .gitignore to make sure build artifacts don't wind
  up in version control.
