Summary:                    [patch] Update for chan_unistim fuctionality
Description: 
During last three month I have worked on improving functionality of Nortel
phones working with asterisk to replace existing Nortel station by
asterisk. Many improvments done, listed below. I have only i2002 phone and
unable to test if new version of channel correctly works with i2204 phone.
If anyone can test it and report issues, it would be great 

New unistim.conf options:
- Added "debug" global option in unistim.conf, that enable debug when
module loaded
- Added "sharpdial" option, enable sending call whet # key pressed

New features:
- ability for changing display language (tested on Russian language). Use
.po files in encoding, able to display
  ISO 8859-1, ISO 8859-2, ISO 8859-4, ISO 8859-5, ISO 2022-JP. For
selecting language can be used option "language" in
  unistim.conf or screen menu.
- Support for multilines
- Support for holding multiple lines
- More fixes for display on i2002 phone
- Configurable keys for sending and received history
- Menu for selecting codec, contrast (not yet completed) or display
language
- Show clock at first line of idle phone 
- Add ability for pick up call 
- Pick up call by using on-screen soft key
- Change displaying list of received or send calls (callerid, time and
caller name on different screens, listed by lef-right keys)

Changes:
- Changed entering on screen phone number, so any number of digits can be
entered
- rtp_port now used start rtp port
- list of dial tone frequecies now loaded from indications.conf and not
hardcoded
- Key with globe icon how calls menu and not directly codec selection

Fixes:
- https://issues.asterisk.org/view.php?id=17406 Correct updating LED when
switching between speekerphone and
handset or hanging up
- https://issues.asterisk.org/view.php?id=17327 Multiple crashes when using
phone 
- https://issues.asterisk.org/view.php?id=16867 Fixed playing dialtone in some
scenarious when conversation
already started
- Fixed dispalying on-screen information when using Redial softkey (DN
number and timer displayed). 
- Not sending short ring in case of call forward enabled on phone

---------------------------------------------------------------------- 
Diff for chan_unistim between 1.8 and 1.6.2 is about 26kilobytes, most of
this changes need to be reverted in my patch to make it working with 1.6.2.
Most noticeable change in 1.8 is the new RTP engine.
