    Add a flag to disable the Background behavior, for AGI users.
    This is in a section of code that relates to two other issues, namely
    issue #14011 and issue #14940), one of which was the behavior of
    Background when called with a context argument that matched the current
    context.  This fix broke FreePBX, however, in a post-Dial situation.
    Needless to say, this is an extremely difficult collision of several
    different issues.  While the use of an exception flag is ugly, fixing all
    of the issues linked is rather difficult (although if someone would like
    to propose a better solution, we're happy to entertain that suggestion).
    (closes issue #16434)
