The rendering implementation is needed for using Gio UI with external
window libraries such as GLFW. Expose it in the new package gpu.

We'd like to support Gio using a different renderer binding than
the builtin. A first step is to define the Functions interface
in package gl, and extract the concrete implementations to a
separate package.

Currently the golang.org/x/sys package is missing the Pipe2 call for OpenBSD.
The call exists on OpenBSD, it just isn't exposed.
This diff was tested buy adding the Pipe2 call and setting:
go mod edit -replace=golang.org/x/sys=/pat/to/modified/sys

Issue #77 seems to be caused by eglGetDisplay returning a zero
EGLDisplay, yet eglGetError returns EGL_SUCCESS. Since EGLDisplay
is not necessary a pointer type, the zero value may be valid.

EGL contexts don't need locking, so their Lock and Unlock methods
are empty. Remove them and add them where necessary instead.

Instead of calling from the low level context into the window
for its surface and dimensions, add a Context.MakeCurrent method
that does it directly.
The result is simpler and clearer logic. For example, synchronization
is obviously no longer needed. It wasn't necessary before, but the
reason was unclear.
