Move emulator GLES from development.git to sdk.git
The emulator GLES support has two interfaces: a host shared library interface used by QEMU, and a protocol between the platform and the host. The host library interface is not versioned; QEMU and the GLES renderer must match. The protocol on the other hand must be backwards compatible: a new GLES renderer must support an older platform image. Thus for branching purposes it makes more sense to put the GLES renderer in sdk.git, which is branched along with qemu.git for SDK releases. Platform images will be built against the protocol version in the platform branch of sdk.git. Change-Id: Ie73fce12815c9740e27d0f56caa53c6ceb3d30cc
