swaybar: complete barconfig_update event handling

Browse source 
This adds complete support for the barconfig_update ipc event. This also
changes the bar command and subcommand handlers to correctly emit the
event. This makes it so all bar subcommands other than id and
swaybar_command are dynamically changeable at runtime. sway-bar.5 has
been updated accordingly

# COMMANDS
*status_command* <status command>
Executes the bar _status command_ with _sh -c_. Each line of text printed
to stdout from this command will be displayed in the status area of the
bar. You may also use swaybar's JSON status line protocol. See
*swaybar-protocol*(7) for more information on the protocol
If running this command via IPC, you can disable a running status command by
setting the command to a single dash: _swaybar bar bar-0 status\_command -_
*pango_markup* enabled|disabled
Enables or disables pango markup for status lines. This has no effect on
status lines using the i3bar JSON protocol.
The following commands may only be used in the configuration file.
*id* <bar_id>
Sets the ID of the bar.
*position* top|bottom
Sets position of the bar. Default is _bottom_.
*output* <output>
Restrict the bar to a certain output, can be specified multiple times. If
the output command is omitted, the bar will be displayed on all outputs.
*swaybar_command* <command>
Executes custom bar command. Default is _swaybar_.
*font* <font>
Specifies the font to be used in the bar. _font_ should be specified as a
pango font description. For more information on pango font descriptions,
see https://developer.gnome.org/pango/stable/pango-Fonts.html#pango-font-description-from-string
*separator_symbol* <symbol>
Specifies the separator symbol to separate blocks on the bar.
*wrap_scroll* yes|no
Enables or disables wrapping when scrolling through workspaces with the
scroll wheel. Default is _no_.
*workspace_buttons* yes|no
Enables or disables workspace buttons on the bar. Default is _yes_.
*strip_workspace_name* yes|no
If set to _yes_, then workspace names will be omitted from the workspace
button and only the custom number will be shown. Default is _no_.
*strip_workspace_numbers* yes|no
If set to _yes_, then workspace numbers will be omitted from the workspace
button and only the custom name will be shown. Default is _no_.
*binding_mode_indicator* yes|no
Enable or disable binding mode indicator. Default is _yes_.
*gaps* <all> | <horizontal> <vertical> | <top> <right> <bottom> <left>
Sets the gaps from the edge of the screen for the bar. Gaps can either be
set all at once, per direction, or per side. Note that only sides that
touch an edge of the screen can have gaps. For the side that does not
touch an edge of the screen, per-side outer gaps for workspaces may be of
use.
*height* <height>
Sets the height of the bar. Default height (0) will match the font size.
The following commands may be used either in the configuration file or at
runtime.
*bindcode* [--release] <event-code> <command>
Executes _command_ when the mouse button has been pressed (or if _released_

command _nop_.

*height* <height>
Sets the height of the bar. Default height (0) will match the font size.
*hidden_state* hide|show [<bar-id>]
Specifies the behaviour of the bar when it is in _hide_ mode. When the
hidden state is _hide_, then it is normally hidden, and only unhidden by
pressing the modifier key or in case of urgency hints. When the hidden
state is _show_, then it is permanently visible, drawn on top of the
currently visible workspace. Default is _hide_.
For compatibility with i3, _bar hidden_state hide|show [<bar-id>]_ is
supported along with the sway only _bar <bar-id> hidden_state hide|show_
syntax. When using the i3 syntax, if _bar-id_ is omitted, the hidden_state
will be changed for all bars. Attempting to use _bar <bar-id1>
hidden_state hide|show <bar-id2>_ will result in an error due to
conflicting bar ids.
*mode* dock|hide|invisible|overlay [<bar-id>]
Specifies the visibility of the bar. In _dock_ mode, it is permanently
visible at one edge of the screen. In _hide_ mode, it is hidden unless the
modifier key is pressed, though this behaviour depends on the hidden state.
