riscv: Add support for enabling SV48 mode
This increases the size of the user map from 256GB to 128TB. The kernel
map is left unchanged for now.
For now SV48 mode is left disabled by default, but can be enabled with a
tunable. Note that extant hardware does not implement SV48, but QEMU
does.
- In pmap_bootstrap(), allocate a L0 page and attempt to enable SV48
mode. If the write to SATP doesn't take, the kernel continues to run
in SV39 mode.
- Define VM_MAX_USER_ADDRESS to refer to the SV48 limit. In SV39 mode,
the region [VM_MAX_USER_ADDRESS_SV39, VM_MAX_USER_ADDRESS_SV48] is not
mappable.

libc __sfvwrite(): roll back FILE buffer pointer on fflush error
__sfvwrite() advances the pointer before calling fflush. If fflush()

buf_alloc(): Stop using LK_NOWAIT, use LK_NOWITNESS

avoids the need for a 'camcontrol rescan' on the device which detaches

nvmecontrol's ability to do the same thing w/o changing the exposed
nvme/nvd/nda device. We scan the target and not the LUN because dual
actuator drives have multiple LUNs, but the firmware is global across
many vendors' drives (and the so far theoretical ones that aren't won't
be harmed by the rescan).
Since the underlying struct disk is now preserved accross this
operation, it's now possible to upgrade firmware of a root device w/o
crashing the system. On systems that are quite busy, the worst that
happens is that certain operaions are reported cancelled when the new
firmware is activated. These operations are retried with the normal CAM
recovery mechanisms and will work on the retry. The only visible hiccup
is the time that new firmware is flashing / initializing. One should not
consider this operation completely risk free, however, since not all
drives are well behaved after a firmware download.

vt_vga: fix colour in pixel blocks with more than 4 colours
VGA hardware provides many different graphics and data access modes,
each with different capabilities and limitations.
VGA vt(4) graphics mode operates on blocks of pixels at a time. When a
given pixel block contains only two colours the vt_vga driver uses write
mode 3. When the block contains more than two colours it uses write
mode 0. This is done because two-colour write mode 3 is much more
efficient.
In practice write mode 3 is used most of the time, as there is often a
single foreground colour and single background colour across the entire
console. One common exception requiring the use of mode 0 is when the
mouse cursor is drawn over a background other than black, as we need
black and white for the cursor in addition to the background colour.
VGA's default 16-colour palette provides the same set of colours as the
system console, but in a different order. Previously we configured a
non-default VGA palette that had the same colours at the same indexes.
However, this caused anything drawn before the kernel started (drawn by
the loader, for instance) to change colours once the kernel configured
the new, non-default palette.
In 5e251aec8636 we switched to leaving the default VGA palette in place,
translating console colour indexes to VGA colour indexes as necessary.
This translation was missed for the write mode 0 case for pixel blocks
with more than two colours.
