Bug 852: Remove CPU sourced data API entry where not allowed (ES3 and GL core >= 3.0) ; GL2 cfg: Ignore GL2ES3 symbols (super)

Remove CPU sourced data API entries via new config 'BufferObjectOnly  <name>',
listed in 'gl-common-gpubufferonly.cfg' and included in ES3 and all GL core >= 3 interfaces.

If BufferObjectOnly is defined for a function, only the 'long offset' variant is being emitted.

Due to limitations of GlueGen's 'ExtendedInterfaceSymbolsIgnore A.java', which only
identifies the function name and not the signature - all CPU sourced variants
are manually added to the compatibility and ES2 GL profiles via '*-common-cpubufferJavaCode.java' files.

GLContext: Added 'isCPUSourcedAvail()' to determine whether context allows CPU sourced data,
i.e. for GL2ES1 and GLES2 ctx.

GLContext/GLProfile/GL: isGLES2() now returns false if having a ES3 context due to 'CPU sourced'
incompatibility!

+++

GL2 cfg: Added ignore GL2ES3 symbols of it's superclass, removing duplicated symbols.
