Introduce a spinlock for synchronizing access to the video output hardware

in syscons. This replaces a simple access semaphore that was assumed to be protected by Giant but often was not. If two threads that were otherwise SMP-safe called printf at the same time, there was a high likelyhood that the semaphore would get corrupted and result in a permanently frozen video console. This is similar to what is already done in the serial console drivers.

Add a font width argument to vi_load_font_t, vi_save_font_t and vi_putm_t

and do some preparations for handling 12x22 fonts (currently lots of code implies and/or hardcodes a font width of 8 pixels). This will be required on sparc64 which uses a default font size of 12x22 in order to add font loading and saving support as well as to use a syscons(4)-supplied mouse pointer image. This API breakage is committed now so it can be MFC'ed in time for 6.0 and later on upcoming framebuffer drivers destined for use on sparc64 and which are expected to rely on using font loading internally and on a syscons(4)-supplied mouse pointer image can be easily MFC'ed to RELENG_6 rather than requiring a backport. Tested on: i386, sparc64, make universe MFC after: 1 week

by explicitly setting sc->font_width, in the same places where sc->font_size is set, instead of relying on the default initialized value of 0 for sc->font_width. PR: kern/84836 Reported by: Andrey V. Elsukov MFC after: 2 days

Add VESA mode support for syscons, which enables the support of 15, 16,

24, and 32 bit modes. To use that, syscons(4) must be built with the compile time option 'options SC_PIXEL_MODE', and VESA support (a.k.a. vesa.ko) must be either loaded, or be compiled into the kernel. Do not return EINVAL when the mouse state is changed to what it already is, which seems to cause problems when you have two mice attached, and applications are not likely obtain useful information through the EINVAL caused by showing the mouse pointer twice. Teach vidcontrol(8) about mode names like MODE_, where is the video mode number from the vidcontrol -i mode output. Also, revert the video mode if something fails.

Also some minor style cleanups.

- Add a font width field to struct scr_stat. Use this instead of '8'.

- Use the values in the video info for the font size and width instead of second guessing.
