Some subrs (e.g. x-file-dialog) create X windows and block the execution of

The Emacs code is buggy, see https://github.com/ch11ng/exwm/issues/39https://github.com/ch11ng/exwm/pull/42
* RandR module is now made optional; users can enable it with
`exwm-randr-enable`.
* Correct the calculation of sizes/coordinates at various places.
* Input focus is now tracked with (Emacs) window instead of buffer since the
latter can be ambiguous in multi-screen settings.
This commit should fix most input focus bugs (especially those related to
floating windows). The actual settings of input focus are delayed to exclude
redundant event. Dead code since this commit is removed.
This commit also fixes a bug for non-floating windows converted form floating
state. The workaround for `ido-mode` is also improved to properly handle
`exwm-mode` buffers.
* Prevent switching to floating windows or windows on other workspaces
* Provide a workaround for `ido-mode` (can be enabled with
`(exwm-enable-ido-workaround)`)
Remove `exwm--with-current-id`, which was introduced to as a wrapper to
`with-current-buffer` to do extra checks. Note that in functions run as hooks,
the validation of window ID is still required as they are not synchronized with
events.
`emacsclient` started with `-c` or `-t` argument create a new frame that shall
not be used to manage X windows.
Also fix some related input focus issues (with some remaining unfixed).
Close#17.
* Relax the conditions to refresh layout; this may introduce some overheads
though
* Fix the problem when `*scratch*` buffer is killed; close#12
* Enhance `exwm-reset` by forcing layout refresh in it. This should allow users
to overcome some layout bugs
* Fix input focus lost after moving window to another workspace
* Enhance `exwm-reset` to provide user a way to reset input focus when it's
lost unexpectedly
* Fix `exwm-reset`
* Make input mode buffer local
* Allow window to stay in `char-mode` while setting input focus to other window
or switching to other workspace
* Correct ConfigureNotify events sent to fullscreen windows.
* Exit fullscreen mode before switching workspace.
* Temporarily treat `xcb:Atom:_NET_WM_STATE_ABOVE` as
`xcb:Atom:_NET_WM_STATE_FULLSCREEN` since
a) "plugin-container" (Flash Player) seems only set this, and
b) it's not normally used by applications.
This makes fullscreen videos working in e.g. iceweasel.
