ecore-buffer: Add ecore_buffer library to EFL.
Summary:
Ecore_Buffer is abstraction of graphic buffer.
it supports backend of shm, x11_dri2 and x11_dri3 for now,
and this library also provides method to share buffers between processes.
Ecore_Buffer_Provider and Ecore_Buffer_Consumer is for this, sharing buffer.
provider draws something in to Ecore_Buffer, and consumer receives and displays it.
the binary, bq_mgr is a connection maker for buffer provider and consumer.
it can be included Enlightenment as a deamon later.
@feature
Test Plan:
1. Configure with --enable-ecore-buffer and --enable-always-build-examples to build examples.
2. Run bq_mgr, it connects consumer and provider.
3. Run ecore_buffer_provider_example and ecore_buffer_consumer_example
