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
(leaving squares all over the place).
This doesn't fix the flickering of the screen with vt_vga, because the
sync signal is temporarily stopped and the video memory is cleared.

Like r270273, this has no effect for now, because the cursor is always
drawn. This is in preparation of future changes to vd_bitbltchr_t API.
MFC after: 1 week
Currently, this has no effect, because the cursor is always redrawn
anyway. But this will be useful after improvements to the vd_bitbltchr_t
callback API.
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
avoids to reset the cursor's position to the center of the screen.
This matches syscons' behavior.
While here, remove a trailing space and a redundant variable
declaration.
that's only mostly similar. Specifically word 78 bits are defined for
IDENTIFY DEVICE as
5 Supports Hardware Feature Control
while a IDENTIFY PACKET DEVICE defines them as
5 Asynchronous notification supported
Therefore, only pay attention to bit 5 when we're talking to ATAPI
devices (we don't use the hardware feature control at this time).
Ignore it for ATA devices. Remove kludge that papered over this issue
for Samsung SATA SSDs, since Micron drives also have the bit set and
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).
conversions have been detected and fixed.
It is now possible to add options after the encoding in the parameter
list for convert-keymap.pl. This is currently used to selectively
enable interpretation of the ISO8859-1 currency symbol as the Euro
sign found in ISO5589-15, or to add a Yen symbol in place of '\' for
specific Japanese keyboards. The option are appended to the parameter
list, as in e.g. "convert-keymap.pl german.iso.kbd ISO5589-1 EURO".
The options are appended to the encoding in the form "+EURO" or "+YEN"
in KBDFILES.map, to keep the meaning of the columns intact.

. 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.
The above changes allows me to read the EDID from my HDMI monitor on BBB

several updates to the converter tools. There is now support for hybrid
source keymaps, which e.g. use ISO8859-1 (not -15) but still provide an
Euro key (on the "E" key). ISO8859-1 currency symbols on other keys are
still converted to that character, not the Euro sign. A similar hack was
applied to the Japanese keyboards to add the Yen key, that could not be
expressed in SYSCONS.
Several modifications have been applied after the conversion (removal of
unused accents tables, some reformatting, exchange of a few key symbols).
The German keymap (de.kbd) is now using deadkeys only for those keys,
that behave that way under Windows. There are now ".acc" and ".noacc"
variants, which use deadkeys vs. nodeadkeys for all accent keys.
I'm still in the process of comparing keymaps that existed in different
encodings in SYSCONS. These are generally translated slightly differently,
either because of mistakes, or because of different preferences, or due
to limitations of the respective encoding.

* Remove a duplicate error check in mk_pair_of_sockets
* Always close sockets in the success path of ATF test cases. Don't
bother with the error paths, because those are mostly assertions
anyway. Most of these socket leaks were reported by Coverity.
All of them are harmless, because each ATF test case runs in its
own process.
* Fix the len argument to send in shutdown_send and
shutdown_send_sigpipe. The old version was using sizeof a pointer
instead of sizeof the char array. Reported by Coverity.
* Change a few ATF_CHECK to ATF_REQUIRE if the test can't reasonably
continue past a failure.

I've decided that for 11n rates it's best to start (very) low and work
our way up.
So, from now on, the initial rate for AMRR 11n is MCS4.
It doesn't try MCS12 or MCS20 - at low signal strengths those don't
work very well at all.
AMRR will step the rate control up over time if things work out better.
