add some missing parameter validation in GLES java bindings

- added support for comments in checks.spec
- added most missing checks
- added and commented with // special-cased functions
- added and commented with # functions that are still missing validation checks
- moved glGet* to a special case and updated all the "pnames" from the khronos spec
- changed ifcheck to default to 1 value. this allows us to simplify the checks.spec file
  and handle unknown pnames automatically (they'll be validated against 1 value, if
  it happens to need more, the call will go through but the validation will not
  happen).
- refactored the cpp headers in to a common header + GLES version specific
  header
