Only the Wayland backend needs an wl_egl_window between the wl_surface
and EGL. Move code dealing with the indirection to Wayland specific
code.
Then, introduce the eglDriver interface instead of referencing the
native window type directly. This will help when multiple backends are
supported at runtime (e.g. Wayland+X11).
Finally, move the eglDriver implementation methods from GOOS-specific
code to separate EGL-specific files, allowing EGL types to be used
directly instead of unsafe.Pointer and uinptr.
The result is simpler generic EGL code, and easier path towards X11
support.

Package ui is now only about units except for the Config.Now method.
Remove Now and rename Config to Converter. Add layout.Config to
replace the old ui.Config.

Packages that provide support for external events such as pointer, key and
system are only the beginning. Future packages are expected for clipboard
access, drag and drop, gps positions and so on.
To keep the number of top-level packages under control, move such I/O packages
to the new `io` directory.
The `system` package name was the previous solution to keeping the number of
top-level packages under control: I named it `system` instead of the narrower
`profile` because I expected to put all the less common events into it, turning
`system` into a "package util" smell.
With `io`, package system can be renamed to `profile`.
