Review request for cloudstack, Anshul Gangwar, Brian Federle, Chiradeep Vittal, Jessica Wang,
and Sanjay Tripathi.


tested on master with : git am <patch>

Repository: cloudstack-git


(Port of to master branch)

Firstly, I add a match condition 'altgr' for "Conditional mapping entry" in ajaxviwer.js.
altgr : <altgr state match condition>, -- match on altgr state

It works like the shift match condition.
shift : <shift state match condition>, -- match on shift state

Browser can't detect difference between AltGr and Ctrl+Alt pressed at the same time.
So when the modifier is 896, (Alt(512) + Ctrl(384)) I assume it is the AltGr key and 'altgr'
condition will be true.

In the ajaxkey.js file you got for example:
{type: KEY_DOWN, code: 0x32, modifiers: 0, altgr: true}
to send the spécified key to vnc if user pressed the AltGr (or Ctrl+Alt) key

I wrote the French AZERTY translation table in ajaxkeys.js with the support of AltGr character
(like #{}[]|,etc.)

For example the '#':

{keycode: 51, entry: [         //User type the "3# key and each condition match 'altgr'
{type: KEY_DOWN, code: 0xffea, modifiers: 0, altgr: true}, //press the VNC AltGR key
{type: KEY_DOWN, code: 0x33, modifiers: 0, altgr: true},   //press the 3 key
{type: KEY_UP, code: 0x33, modifiers: 0, altgr: true},     //release it
{type: KEY_UP, code: 0xffea, modifiers: 0, altgr: true}    //release the AltGr key

Thanks for watching my work
