The Qualcomm Atheros reference design code goes through significant

RX before shutting down TX.

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.
This again simplifies vd_bitblt_text_t callback's API.

This fixes a bug when two windows use different fonts, but a longer-term

MFC after: 1 week
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

which relies on SA_SIGINFO not reported for SIG_DFL or SIG_IGN.
In kern_sigaction, ignore flags when resetting. Encapsulate the flag

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

This fixes bad looking refresh when switching window: squares instead
of text, flashing screen, and so on. In the worst case, vt_flush() came
at a very inappropriate timing and the screen was not refreshed at all

Currently, this has no effect, because the cursor is always redrawn
anyway. But this will be useful after improvements to the vd_bitbltchr_t

The vt_device structure members used to store the position of the cursor
as of the last redraw are renamed from vd_mdirty{x,y} to vd_mold{x,y}.
The associated comment is fixed too. Also, their value is now expressed
in pixels, not in character columns/row.

This avoids unnecessary redraw. In particular, during boot, where the
cursor is disabled and its fake position is [0;0], this triggered a
refresh of the whole screen each time vt_flush() is called.

Before the global flag was set/unset using the CONS_MOUSECTL ioctl, and
the per-window flag through the MOUSE_SETLEVEL or MOUSE_SETMODE ioctls.
Also, if the cursor is already enabled/disabled, return immediatly. This

that's only mostly similar. Specifically word 78 bits are defined for

while a IDENTIFY PACKET DEVICE defines them as

Therefore, only pay attention to bit 5 when we're talking to ATAPI

Ignore it for ATA devices. Remove kludge that papered over this issue

the error was caused by this bad interpretation of the spec (which is
quite easy to do, since bits aren't normally overlapping like this).
. interrupt storm detected on "intr70:"; throttling interrupt source;
. Added access serialization on iicbus_transfer(), previously there was
no such protection and a new transfer could easily confuse the
controller;
. Add error checkings (i.e. stop the transfer when a error is detected
and do _not_ overwrite the previous error);
. On command done interrupt do not assume that the transfer was finished
sucessfully as we will receive the command done interrupt even after
errors;
. Simplify the FIFO handling;
. Reset the FIFO between the transfers as the FIFO may contain data from
the last (failed) transfer;
. Fix the iicbus speed for AM335x, which in turn will make better use of
the I2C noise filter (set to one internal clock cycle);
. Move the read and write handler to ithread instead of notifying the

. Fix the comments based on OMAP4 TRM.
