5ba09fb415 core: use GRUB_TERM_ definitions when handling term characters 
* Also use hex value for GRUB_TERM_ESC as '\e' is not in the C standard and is not understood by some compilers

0fd9fa565b charset: Trim away RLM and LRM. 
They are not visible but would otherwise end up as [LRM] or [RLM] squares
with some fonts.

625934ec0f menu_entry: Disable cursor during update_screen() 
When running grub in a VGA console of a KVM pseries guest on PowerPC,
you can see the cursor sweeping over the whole line when entering a
character in editor mode. This is visible because grub always refreshes
the whole line when entering a character in editor mode, and drawing
characters is quite a slow operation with the firmware used for the
powerpc pseries guests (SLOF).
To avoid this ugliness, the cursor should be disabled when refreshing
the screen contents during update_screen().

7136b545c1 Erase backspaced character in grub_username_get 
It probably does not work across linefeed, but hopefully user names are not
that long (and nobody is using terminal that small).

9f2f979bcf always define config_directory and config_file as full pathname 
If configfile is relative pathname, extend it with current ($root) so its
interpretation does not change if $root is changed later.

bb05e313eb use light-gray as default color in normal.mod for consistency 
Defalut font color on PC console seems to be light-gray; this is
what user also gets in rescue prompt and what is defined as
GRUB_TERM_DEFAULT_NORMAL_COLOR. But normal.mod defaults to white.
This makes unpleasant visual effect as colors are changed after kernel
is booted.

Use the same color eveywhere for consistency and default to light-gray
as this is also what at least Linux kernel is using by default.

8f236c1419 Revamp hidden timeout handling 
Add a new timeout_style environment variable and a corresponding
GRUB_TIMEOUT_STYLE configuration key for grub-mkconfig.  This
controls hidden-timeout handling more simply than the previous
arrangements, and pressing any hotkeys associated with menu entries
during the hidden timeout will now boot the corresponding menu entry
immediately.

GRUB_HIDDEN_TIMEOUT=<non-empty> + GRUB_TIMEOUT=<non-zero> now
generates a warning, and if it shows the menu it will do so as if
the second timeout were not present.  Other combinations are
translated into reasonable equivalents.
