  Prevent data corruption in dvbchannel.cpp causing hang

m_is_open was being corrupted by multiple simultaneous modifications,
leading to it managing to create infinite loops within its underlying
data structure. This patch extends the locking of m_hw_lock to cover
all uses of m_is_open, preventing issues.

  A channelscan with mythtv-setup gives sometimes incorrect "Timed out" messages.
This happens when the scan time of a particular transport is extended
because there are SDT's and a NIT to receive but the error message is given
when the original timeout time is exceeded. This is fixed by using
the already present function HasTimedOut to decide if the scan has timed out.

The modified time computation also computes the number of seconds.

  AVSync2: Use frame timestamps to determine elapsed play time

MythTV uses frame count to determine the elapsed time of a recording
for display, jumps, etc. This can be inaccurate with variable rate
content and also with frame doubling being done in the decoder.
This change recalculates the frame count based on the time code.
This ensures MythTV elapsed time will be accurate.

  Valgrind error in DVBStreamHandler / DeviceReadBuffer

The DeviceReadBuffer is now stopped only once at the end of recording
instead of three times. One of the two later stop attempts accessed memory
that was already free'd in a previous stop. This caused valgrind errors
when testing with valgrind and this caused also possibly occasional
segmentation faults of  mythbackend at the end of a recording.

  Video aspect ratio wrong on systems with multiple monitors

On a system with two monitors, positioned horizontally next to each other,
the vertical size of the video in a window is correct but the horizontal size
is about half what it should be.
The same is true for full-screen video, without an enclosing window.

This problem is most likely introduced in commit b2c82a3, dated Feb 1,
"Convert from QDesktopWindow to QScreen".

Before this commit a system with multiple monitors was treaded as "Xinerama".
After this commit a system with mulitple monitors is seen as one big screen
with an area which is the bounding box of the screens of all monitors.
The name display as used in the code now refers to the big "bounding box" screen.

The video aspect ratio computations use the size of the display in mm.
The bug was here that the display size in mm was used in conjunction
with the size in pixels of the first screen.
In order to scale correct the size in pixels of the display has to be used.

Note: the change from QDesktopWidget to QScreen is a Good Thing because
the QDesktopWidget is declared obsolete.
Note: with this fix included the video scaling in a multiple monitor
system is now exact which is better than before, in the "Xinerama" mode.

  Update guide title/subtitle/description with new DVB EIT data

The title/subtitle/description in the guide is now updated
with the latest information received from DVB EIT. The title
is now updated with the newly received data unless the new
title is an empty string.
Previously, the title was only updated if the new title was
longer than the old title. This caused missed recordings when
recording rules are used that refer to the program title.
The same for the subtitle and the description.

Fixes #13057

  No Signal/Noise and no Signal Strength with Si2168-based tuners

The Linux driver for the Si2168 only implements the DVBv5 calls
to retrieve the signal strength etc.
The MythTV code first tries the DVBv3 call and if that fails
with an EOPNOTSUPP then the DVBv5 call is tried.
This worked correct until Linux kernel changed the
error code from EOPNOTSUPP to ENOTSUPP (value 524).
This fix adds a test on ENOTSUPP in addition to the existing
test on EOPNOTSUPP.
