`~.Axes.errorbar` now color cycles when only errorbar color is set

Previously setting the *ecolor* would turn off automatic color cycling for the plot, leading to the

the lines and markers defaulting to whatever the first color in the color cycle was in the case of

multiple plot calls.

`.rcsetup.validate_color_for_prop_cycle` now always raises TypeError for bytes input

Previously, keyword arguments were silently ignored when no positional

arguments were given.

`.Axis.get_minorticklabels` and `.Axis.get_majorticklabels` now returns plain list

Previously, `.Axis.get_minorticklabels` and `.Axis.get_majorticklabels` returns

silent_list. Their return type is now changed to normal list.

`.get_xminorticklabels`, `.get_yminorticklabels`, `.get_zminorticklabels`,

`.Axis.get_ticklabels`, `.get_xmajorticklabels`, `.get_ymajorticklabels` and

`.get_zmajorticklabels` methods will be affected by this change.

Default slider formatter

The default method used to format `.Slider` values has been changed to use a
