Cleanup for a better OpenGL 3.2 integration,

for subsuming extensions:
    - Allow RenameExtensionIntoCore generate duplicate names,
      ie those will not be generated.
    - Add proper comment showing the extension of the symbol.
    - Fail if no 'GLHeader' is specified, but we are processing a GL/ProcAddress config
    - Fail if a GL function is not part of an extension

MethodBinding, ConstantDefinition cleanup:
    - getName() returns the renamed name
    - getOrigName() returns the original
    - getAliasedNames() returns the aliased ones

MethodBinding:
    - Change: equals() operates on renamed name
    - Add: hashCode() function - same criteria as equals()

Impact:
    - All config options etc shall trigger with the renamed name,
      but ignore, rename etc.
    - Generated Java impl. uses the renamed base name as well

Change: emitDefine() uses the ConstantDefinition

Add: JavaConfiguration: dumpRenames()

Change JavaConfiguration.shouldIgnoreInInterface/Impl():
    - respect the renamed symbol name as well

Change JavaEmitter.emitFunctions():
    - only emit a generated MethodBinding once,
      therefor store emitted method bindings in a HashSet

Fix BuildStaticGLInfo:
    - Allow white space at the end of #ifndef and #define
    - Trim strings
    - Allow 'const' qualifier in function pattern

Fix GLEmitter:
    - Fail if no 'GLHeader' is specified, but a RenameIntoCore option ..
    - Don't emit marker defines, marking an extension (ie not part of an extension)

Fix GLJavaMethodBindingEmitter:
    - Fail if a GL function is not part of an extension

Fix PCPP:
    - Pass constant type qualifiers for hex-constants: 'l' 'L' ...

Fix ProcAddressEmitter:
    - Operate on the aliased/renamed name for querying ProcAddress usage
      and generating code.
