[PATCH 0/6] rtems-source-builder patche series for graphic libraries

[Pavel Pisa]

Hello Qiao Yang,

I have applied your patches on RSB master the result
is identical to the last one with updated libPNG.

I have rerun build and all packages has build OK.

Joel, please, apply patches.

For future, I am not sure if these 4.11 related updates
should or should not propagate to RSB 4.11 branch.
But I suggest to have them on master for sure.

The next step should be to consider what to do with
keyboard Microwindows patch.

  microwindows-0.93-dev-without-keyboard.diff

It is required for Raspberry Pi testing for now
but it should be conditional and not applied to other
targets. I hope that I prepare proposal how to
make Microwindows drivers for RTEMS configurable
in future.

But I prefer to solve and think about these after
this round passed to final repositories.

Qiao, thanks for contribution,

                        Pavel
