Liav A c6c3e2a7fd Kernel: Instantiate a TextModeConsole early on if there's no framebuffer ...

If the bootloader that loaded us is providing a framebuffer details from
the Multiboot protocol then we can instantiate a framebuffer console.
Otherwise, we should use a text mode console, assuming that the BIOS and
the bootloader didn't try to modeset the screen resolution so we have is
a VGA 80x25 text mode being displayed on screen.

Since "boot_framebuffer_console" is no longer a good representative as a
global variable name, it's changed to g_boot_console to match the fact
that it can be assigned with a text mode console and not framebuffer
console if needed.
