fix another regression from 27c6d111 this probably broke the mad boss extension

FS-3227 --resolve this looks like sane changes.  My only complaint was the formatting.  Watch for whitespace indentation by looking at the code in emacs or vi where it should be tabed properly.

FS-2877 After further review I can concede the point that we should always say partial considering how we do things.  With this commit we should at least be sending separate partial updates for each existing dialog to everyone with a subscription.  If we need to introduce more data, consolidate them etc.  We need to do it in small chunks and keep things sane.

add execute_on function so you can have execute_on_answer_1 execute_on_answer_2 execute_on_answer_3 etc

mod_say_ru now support say_string like mod_say_en. Now support channel variables gender,cases can be set in english and russian for example: <action application="set" data="cases=nominativus/>  <action application="set" data="gender=male_h"/> <action application="say" data="ru NUMBER PRONOUNCED  1001"/>

the intent for having the module and lang separate is for things where the same module can use different sets of sounds like en module and en-male or en-female lang (sound dirs) there was indeed a disconnect in the dialplan version of this app.  Originally say was only available in phrase macros so I change the syntax of the say app so you can specify both the module and the lang absolte from the dp with something like he:he as the module name.  BTW: Going forward can you attach the patch or give me instructions on how to get it in raw format or merge it to our local git, I don't really have the time to figure it out just to pull in a patch......

take back in some elements from the reverted patch that still make sense based on code review by Moc, thanks

FS-3176 forget the last patch I forgot there is no way to know the right codec using it the file string way, you will just have to manually specify en.PCMA as before but now it should work

change mod_dptools to use the better method of fetching user xml that does not hang onto the xml root

revert 471bd6df and implement reference counting on the xml roots to achieve the same end result
