Shut down RX before TX - in theory, this should make the chip less likely
to get upset.
The Qualcomm Atheros reference design code goes through significant
hacks to shut down RX before TX. It doesn't even try do do it in the
driver - it actually makes the DMA stop routines in the HAL shut down
RX before shutting down TX.
So, to make this work for chips that aren't the AR9380 and later, do
it in the driver. Shuffle the TX stop/drain HAL calls to be called
*after* the RX stop HAL call.

vt(4): Fix cursor handling in vt_flush()
There were situations where the cursor was not erased/redrawn or its
position was marked as dirty even though it's not displayed. The code is
now more straightforward.
At the same, add a function to determine if the cursor covers a given
area. This is used by backends to know if they need to draw the cursor.
This new function should be paired with a new state in struct vt_device,
called vd_mshown, which indicates if the cursor should be displayed.

vt(4): Add new vd_bitblt_text_t callback, and implement it for vt_vga
Compared to the deprecated vd_bitbltchr_t callback, vd_bitblt_text_t
receives:
o the whole text buffer
o the dirty area
o the mouse cursor (map, position, colors)
This allows the backend to perform optimization on how to draw things.
The goal is to remove vd_bitbltchr_t and vd_putchar_t, once all driver
are converted (only vt_vga is included in this commit).
In vt_vga, this allows to draw the text and the cursor in one pass,
without ever reading from video memory (because it has all the context).
The main benefit is the speed improvement: no more slideshow during
boot!
Other bugs fixed in vt_vga are:
o left-most characters are drawn properly (the left-most pixels were
missing with bold characters and some wide letters such as 'm')
o no more black square around the cursor
o no cursor flickering when the text is scrolling

"FIXME" inside the code.

Ensure that sigaction flags for signal, which disposition is reset to

which relies on SA_SIGINFO not reported for SIG_DFL or SIG_IGN.
In kern_sigaction, ignore flags when resetting. Encapsulate the flag
and disposition testing into helper sigact_flag_test().
On exec, and when delivering signal with SA_RESETHAND flag set,
signals are reset automatically. Use new helper sigdflt(), which
removes duplicated code and corrects all flag bits for the signal.
For proc0, set sigintr bit for all ignored signals. Ignored signals
