1069490 - Add column number to ConsoleEvent, ConsoleStackEntry, nsIStackFrame

Status: RESOLVED FIXED

Description

[Eric Rahm [:erahm] (please no mozreview requests)]

In bug 1060161 we started printing out stack traces with console messages on b2g devices. It was noted that having a column number in addition to a line number would be useful (particularly for minified code).

My proposal is:
   #1 - add an |unsigned long columnNumber| to ConsoleEvent [1] and
        ConsoleStackEntry [2]
   #2 - add a |readonly attribute int32_t columnNumber| to nsIStackFrame [3]
   #3 - |StackFrameToStackEntry| [4] would set ConsoleStackEntry's column number
   #4 - add a |GetColumnNumber| to JSStackFrame [5] that queries "column" value
        of the JS stack object

Thanks for the quick reviews! Try is running, I expect that I'll need to fix a few tests when the results come in: https://tbpl.mozilla.org/?tree=Try&rev=d965bae7a732

Rob, can you take a look at these test updates that handle the new |columnNumber| field on stack traces?
