app, io: [wasm, android] add support for numeric/email keyboard mode

Previously, the on-screen keyboard always displays the text keyboard,
(QWERTY or equivalent).

For optimal user experience, it's possible to specify the keyboard type
using `InputHint`. The on-screen keyboard will provide shortcuts or
restrict what the user can input.

Due to some limitations (gio#116), only numeric and text keyboards are
supported on Android.

io/key,io/pointer: forbid nil tags for InputOps

Forcing a non-nil tag ensures that all handler tags are either unique,
or intentionally equal. Additionally, a nil tag has special meaning in

io/router/key: add explicit tag to FocusOp; make last SoftKeyboardOp apply

The target of FocusOp is too subtle; be explicit instead and remove
any doubt.

Multiple SoftKeyboardOp in a single frame is rare, but if they do occur,
they should behave as if they were from separate frames: the last one

As a side-effect the key event router can be much simplified.

io/key: improve InputOp focus and blur

The existing implementation cannot remove the focus of some widget,
doesn't have an option to focus without display the on-screen keyboard
and it automatically focuses the first InputOp, aggressively.

That change aims to make possible: remove focus from any widget. Add
focus without displaying the on-screen-keyboard/soft keyboard. Don't
automatically focus any widget. Don't recover focus when the widget is
visible again.

Fixes gio#180.

Many operations do not pass refs to Write. Similarly adding
...interface{} requires constructing a slice, which is slow.

This cuts about 100ns from RRect and Border benchmark.

Implement key state for the following platforms:

all: rename io/event.Key to Tag

Key had an unfortunate association with keyboard input.

This is an API change. The following rewrites were run to fixup
Gio code:

        $ gofmt -r 'pointer.InputOp{Key:a} -> pointer.InputOp{Tag:a}' -w .
        $ gofmt -r 'pointer.InputOp{Key:a, Grab:b} -> pointer.InputOp{Tag:a, Grab:b}' -w .
        $ gofmt -r 'key.InputOp{Key:a} -> key.InputOp{Tag:a}' -w .
        $ gofmt -r 'key.InputOp{Key:a, Focus:b} -> key.InputOp{Tag:a, Focus:b}' -w .
        $ gofmt -r 'event.Key -> event.Tag' -w .

app/internal/window: allow punctuation as keycode events

Allows things like "ctrl-{" and ".".

All punctuation is returned as-is, e.g. "!" is "!", not "shift-1", and
"{" is "{", not "shift-[".

Also add the Enter key as a known key (fn-return on my Mac).

io: give event packages a common prefix

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`.
