0657b2a559 alsamixer: small optimizations
textbox.c, mixer_display.c:
  - Replaced manual line drawing code `for (...) mvwaddch(...)` by the
    functions `mvwhline/mvwvline` provided by standard curses

card_select.c, proc_files.c:
  - Moved duplicate code in the create() functions to menu_widget_create()
    in menu_widget.c

card_select.c:
  - Removed redundant calls to sprintf()

device_name.c:
  - Combined multiple calls to form_opts_off()
  - Recognize ASCII DEL (127) as backspace

widget.c:
  - Uncommented code for setting a dummy key handler (all existing
    widgets do provide a key handling function)

32dc22c2bf alsamixer: Use a struct for storing color attributes
This commit is a preparation for the configuration file parser.

The `int attr_*` variables have been moved into a separate struct.
Members of that struct are alphabetically ordered, so an attribute can
later be accessed by its name.

Added `int get_color_pair(short fg, short bg)` for returning or
creating a color pair number.

Added call to `use_default_colors()` for enabling access to the
terminal's default color (-1).

ba1c5357a1 alsamixer: added mouse support
Mouse support has been added for mixer_widget.c, card_select.c and
proc_files.c.

In the mixer widget the mouse is handled as follows:
- After an element has been printed in mixer_display.c, a call to
  clickable_set() will store the coordinates of the drawn area plus the
  command enum that should be executed on click. An optional argument
  holds an index which points to the selected mixer control.
- on_mouse_click() searches for a matching rectangle, focuses the mixer
  control and returns the command enum.

In the menu widgets, the menu_driver() function handles mouse input.

6e9e84ba60 alsamixer: Replaced hardcoded keys by binding arrays
This commit is a preparation for making keybindings configurable.

The hardcoded keys in the switch statements of mixer_widget.c,
textbox.c, proc_files.c and card_select.c have been replaced by
command enums. The command that shall be executed is looked up in
the arrays `mixer_bindings` and `textbox_bindings`.

The channel_mask enum has been made public, since LEFT and RIGHT are
used as command arguments in bindings.c.
