Subject: [PATCH] bootmenu: Replace reverse for truetype console
The truetype console doesn't support many ANSI escape sequences, among
those the reverse sequence is *broken*. It reverses the text, but does
not change the background color.
This, instead, uses characters to show which option is currently active.

Subject: [PATCH] autoboot: Make all prompts configurable
This is a multi-purpose commit. Though it is hard to split into distinct
changes.
1. Allows the non-keyed prompt to be configured
This is self-explanatory. This allows better customization for the
integrator. Though, more to the point, this reduces the confusion that
comes from the option name and description. Now it is used for all
auto-boot prompts, not only for the keyed prompt.
2. Redraws using ANSI escapes
This is required for (1), as we can't backspace over the arbitrary
amount of characters to redraw the countdown.
This is done through resetting the column to 1 and clearing the line for
maximum compatibility. Tested against serial, default dm_video and the
truetype console.

Subject: [PATCH] [WIP] cli: Clear ctrl+c before running a command
This fixes an issue where:
With an environment like so:
bootmenu_0=Default U-Boot boot=run distro_bootcmd; $menucmd -1
* Running bootmenu
* Running the option
* Cancelling using CTRL-C
Would show the menu as expected, but running *any* command
post-cancellation would spuriously exit in unexplainable ways.
