Tested by: nickpeirson, murf
1. replaced all refs to bzero and bcopy to memset and memmove instead.
2. added a note to the CODING-GUIDELINES
3. add two macros to asterisk.h to prevent bzero, bcopy from creeping
back into the source
4. removed bzero from configure, configure.ac, autoconfig.h.in

fix a bug which caused a crash when a videodevice was
specified after startgui=1 in the config file. This also
involves a slightly different method to determine if the
gui is active or not.

giving you support for up to 9 video sources (e.g. webcams,
or X11 grabbers, etc.) active at once, displaying thumbnails for
each of them in the main GUI window, and with the ability to switch
between them on the fly during a conversation.
The code also implements a 'Picture in Picture' feature,
allowing you to select any source as primary or secondary,
and move the PiP window by just dragging it with the mouse.
The window looks like this:

a number to dial in the 'message' area under the
keypad.
Now you can make calls using the keypad as a regular phone
(or the keyboard for chars not present on the keypad)

commands so you can start and stop the gui even outside
of a call. This is convenient for testing, and also for
using the keypad to pick up a call, and to dial a number
(the latter not yet implemented, but should be close).

The main code to implement the textarea is in console_board.c,
and uses a simple png image with the font, blitting characters
on the designated areas of the main screen.
Additionally we provide some annotations in the image used
as a skin to indicate which areas are used for text messages.
(images will be committed separately).
At the moment the dialog area is only used to display a running
counter, just as a proof of concept.

to add more entries. This required moving struct grab_desc to the common
header, and adding an entry in the Makefile.
On passing, cleanup some comments and file headers (some are still missing).

SDL is also detected at runtime).
Now we should be able to stream video even without a rendering device
(useful for remote monitoring).

are in separate files (still #include'd because of tangling in the data
structures, but this is going to be cleaned up).
The video grabbing functions still need to be moved to a separate file.

With this change we can do
setenv SDL_VIDEODRIVER aalib
and output to an ascii window (which is still in an X11 window).
If you also do
unsetenv DISPLAY
then the output goes into the main asterisk window, unfortunately
it interferes with the normal output so you don't see much.
In any case, i don't think we are very far away from having a working
xterm videophone!

from 'keypad_entry' to 'region'. Fix the example file accordingly.
Also make some fixes in the code do reset entries on reload of the keypad.
The recently committed kpad2.jpg has the correct names.

console_video.c
This will ease the task of splitting console_video.c into its components
(V4L and X11 grabbers, various video codecs and packetizers, SDL),
as well as ease future extensions (e.g. additional video sources,
codecs and rendering engines).
For the time being nothing changes for users: video support is off by
default, and requires -DHAVE_VIDEO_CONSOLE on the command line to be included
(if SDL and FFMPEG are available).

see description in config.h .
They are a variant of the set of macros i used in chan_oss.c,
structured in a way to be more robust to the presence of
spurious ';' - basically, they define wrappers for 'do {'
and '} while (0)', plus some helper functions to deal with simple
cases such as ast_copy_string, ast_malloc, strtoul, ast_true ...
The prefix (CV_ as 'Config Variable') tries to be easy to remember
and has been chosen to not conflict with other existing macros in the tree.
For the time being, I have only updated the three source files in the
tree that used the old M_* macros. Hopefully, more files will be
converted.
NOTE:
I understand that inventing my own dialect of C is generally wrong;
however, the lack of adequate support in the language encourages
lazy programming practices (such as ignoring errors, bounds, etc.)
and this increases the chance of vulnerability in the code, especially
because we are parsing user input here.
Hopefully, these macros and the use of ast_parse_arg (in config.h)
should encourage the programmer to write more robust code.

This is disabled in the default build, you need to explicitly enable it
compiling with
make COPTS=-DHAVE_VIDEO_CONSOLE
In return, you will be able to do a video call with chan_oss, using
the webcam (or X11 grabbing) as local source, and rendering the
incoming stream on your screen. Currently supported formats are
h261, h263, h263+, h264, mpeg4 (all through the avcodec lib, part
of ffmpeg).
Incoming video is on the left, outgoing video is on the right,
while the center displays a keypad (if configured so).
Right clicking on the video windows increases the size,
center clicking reduces the size.
Dragging the mouse (with the left key) on the right window
while the X11 grabber is active moves the grab area.
This is the result of work by Sergio Fadda, Marta Carbone
and myself, all properly disclaimed to digium.
Note, there is a lot of work left to do in this module,
including adding support for Video4LinuxV2 (I have patches
from Matteo Brancaleoni which should be integrated),
and making the GUI a lot more friendly than it is now
(e.g. supporting merging or switching among multiple sources,
a text window, and more).
