Boot manager: Niveus window, keys and wells, Instrument Sans, pointer, other systems, working power entries

Browse source 
The F8 menu is redrawn in the Niveus language: a window with three lights,
bevelled keys with a lit edge, wells for panels, anti-aliased corners and a
soft shadow, set in Instrument Sans rasterised into include/gfx/nvfont.h
(tools/python/mknvfont.py, make nvfont). Scale doubles on screens 1400 px tall
or more. Lists taller than the screen scroll.

The keyboard still drives everything, and a mouse, touchpad or tablet does
too: both UEFI pointer protocols are polled, hover moves the highlight, a
click activates. The cursor stays hidden until the pointer has really done
something, since the firmware installs a pointer protocol with or without a
mouse. The 'keep this resolution?' countdown is one ten-second budget however
many times the pointer moves.

Loaders found at well-known paths on any volume (Windows, Ubuntu, Debian,
Fedora, Arch, openSUSE, systemd-boot, rEFInd, other BOOTX64.EFI) are listed
and chain-loaded with LoadImage/StartImage. 'Reboot to firmware' used to halt;
it now sets OsIndications and restarts, and Restart and Shut Down call
ResetSystem.

Checked under QEMU+OVMF: menu, resolution list (incl. 2560x1600 at double
scale), system information, shut down, firmware setup, chain-loading a copy of
the loader from a second disk, and a full boot of the ISO to the login prompt.
Pointer hover and click were checked only with synthetic events: in this setup
a USB mouse or tablet delivered no event to the loader (one USB I/O handle
appeared but no pointer protocol came from it), and why was not established.
