dropping its usage (GLArrayDataWrapper validation)
Skip GLProfile based index, comps, type validation, might not be future proof.

GLContext.isGL3bcAvailable() check
Julien Gouesse resolved this odd issue, where a requested GL2 profile was mapped to GL3bc but is not implemented,
see <https://forum.jogamp.org/InternalError-XXX0-profile-2-GL2-gt-profileImpl-GL3bc-not-mapped-td4041754i20.html#a4042018>.
I exploded his patch a little to reuse the GLContext.getAvailableGLProfileName() result
and simplify the conditional statement.
This might need more testing perhaps, plus analyis why GLContext.getAvailableGLProfileName()
offers GL3bc but is not available via GLContext.isGL3bcAvailable() check.

GLProfile.computeProfileImpl(..) as of Bug 1084 is not the culprit here and its hardware criteria filter works.
The issue is commit 99a064327bf991318841c858d21d13e55d6b39db of Bug 1203,
in particular the change in GLProfile re:
"Merge computed EGL-Profile-Map (1) and Desktop-Profile-Map (2)
per device, instead of just using the last computation,
preserving and favoratizing the Desktop-Profile-Map."
Here the Desktop-Profile-Map overwrites the EGL-Profile-Map and hence
the software mapping gets used.
Indeed, this is a regression cause by the work of Bug 1203.
+++
Resolution is to revert the explicit 'union mapping'
and rely on an enhanced 'GLContextImpl.remapAvailableGLVersions(fromDevice, toDevice)' function.
Here the EGLDrawableFactory _already_ maps the EGL device's GL Versions to the 'host' device (e.g. X11).
This has to be refined so that the remap will not overwrite the 'host' device's already detected GL Versions.
That alone is enough, so that GLProfile can simply use the 'mappedEGLProfiles' of the 'host' device if detected, which already is a merged mapping of X11 host- and EGL sub-device.
In case no 'mappedEGLProfiles' are available, we simply use the 'mappedDesktopProfiles'.

version/profile, also ..
also, if requested version is within GL3CompatNonCompliant valid range, i.e. < 3.1,
the detected actual version will be clipped for valid mapping to the requested data.
Here it might be essential to know, that all versions are being 'scanned'
via mapGLVersions from high to low.
Therefor Version 3.0 would be tried before 2.0
and both will be mapped to the clipped actual version 3.0.
The true actual version could be the maximum, however,
using the very same would lead to trying an invalid unavailable GLProfile.

using our OpenJFK 9 x86_64 and arm64 build.
Test demo class is 'com.jogamp.opengl.demos.ios.Hello',
residing in the new demo folder 'src/demos/com/jogamp/opengl/demos/ios/Hello.java'.
This commit does not yet include a working NEWT
specialization for iOS, but it shall followup soon.
Instead this commit demonstrates JOGL operating on
native UIWindow, UIView and CAEAGLLayer as provided by
Nativewindow's IOSUtil.
Test Video https://www.youtube.com/watch?v=Z4lUQNFTGMI
+++
Notable bug: The FBO used and sharing the COLORBUFFER RENDERBUFFER
memory resources with CAEAGLLayer to be displayed in the UIView
seemingly cannot handle GL_DEPTH_COMPONENT16, GL_DEPTH_COMPONENT24
or GL_DEPTH_COMPONENT32 depth buffer - none at all (Device + Simulation).
Therefor the default demo GLEventListener chosen here
don't require a depth buffer ;-)
This issue can hopefully be mitigated with other means
than using a flat FBO sink similar to FBO multisampling.

- GLProfile
- Add 'hasGL234OnEGLImpl' handling, i.e. GL* profiles on EGL devices
- Properly handle EGL's 'GLDynamicLookupHelper' queries for ES2, ES1 and GL* profiles,
i.e. allow each one to fail seperately.
- Merge computed EGL-Profile-Map (1) and Desktop-Profile-Map (2)
per device, instead of just using the last computation,
preserving and favoratizing the Desktop-Profile-Map.
- GLContextImpl.mapGLVersions(..): Map ES* profiles if having an EGLGraphicsDevice
and not disabled via GLProfile.disableOpenGLES.
- EGLContext
- createContextARBImpl(..): Use the EGL_CONTEXT_MINOR_VERSION_KHR if supported
- GLContext* accessibility: Remove unused entries, add newly used ones
- EGLDrawableFactory
- Fix a bug regarding detection of 'OpenGL' API for EGL
- SharedResource: Use detailed knowledge of each profile
- Only create one drawable and context for probing maximum,
utilizing 'GLContextImpl.MappedGLVersionListener'
to detect all mapped profiles for 'SharedResource' instance.
- Detect whether the probed/mapped device
can be mapped to the default-EGL-device, i.e.:
- current device is not the default-EGL-device
- default-EGL-device is valid and could be mapped (beforehand)
- same connection
In this case, no probing/mapping is performed
and the default-EGL-device mapped data being reused and remapped
to the requested device.
- When mapping/probing, attempt to use a surfaceless context first,
allowing same codepath for default-EGL-device and native-device (X11, ..).
This avoids using pbuffer if using default-EGL-device
and a dummy onscreen window if using a native-device (X11, ..).
If this fails, continue as usual ..
- default-EGL-device -> pbuffer
- native-device (X11, ..) -> dummy onscreen window
