Unified HMI: initial commit

This is the initial commit for RVGPU of Unified HMI.

`Unified HMI` is a common platform that promotes UX innovation
in integrated cockpits and enables flexible information display
from various applications across multiple displays.

`RVGPU` is a client-server based rendering engine
that creates 3D commands on a client device, sends them to a server
for GPU rendering, and displays the results.

- create new layer, meta-uhmi
- create sub-layer, meta-rvgpu
- add 1 feature to enable basesystem, agl-rvgpu

+
+Don't use pkg-config to lookup the path of a binary that's in the path.
+
+Alternatively we'd have to prefix the path returned by pkg-config with
+PKG_CONFIG_SYSROOT_DIR.

+Subject: [PATCH] glBufferData: Update resource backing memory.
+
+Update buffer backing memory on buffer initialization with data.
+This is workaround for UHMI project, where
+VIRTIO_GPU_CMD_TRANSFER_FROM_HOST_3D command is not implemented.
+
+The problem is in the following use-case:
+1) glBufferData --- reserves guest memory "backing" for resource,
+but doesn't fill it with data. Instead, data is serialized into
+virgl internal command and sent using VIRTIO_GPU_CMD_SUBMIT_3D
+comand. This command is opaque for rproxy/rvdds and serialized cmd buffer
+is just forwarded to virglrenderer, where it is deserialized and
+used for initialization of internal "gpu" memory with this data.
+2) glMapBuffer --- this calls TRANSFER_FROM_HOST_3D, which asks host/rproxy-->
+rvdds/virglrenderer to update backing memory (on source) with buffer data.
+And further this backing memory is mapped to guest application.
+In case of UHMI, TRANSFER_FROM_HOST_3D is not implemented, thus the memory is
+not "initialized".
+3) Modify buffer memory, but not whole memory, just some chunks.
+4) glUnmapBuffer --- this will trigger VIRTIO_GPU_CMD_TRANSFER_TO_HOST_3D
+command, which will send to target whole buffer memory and will overwrite
+previous memory. It's ok for modified in step 3 memory, but other is
+just garbage (I always saw zero filled memory).
+
+The above scenario produces artifacts on buffer-scene of glmark, in case of
+"update-method=map", which forces glmark to use 1-4 flow.
+
+As a workaround, fill buffer backing memory with data on step 1.
