    Move 300 bytes around on the stack, to make more room for an extension buffer.
    This allows more concurrent extensions to be copied for a single voicemail,
    without creating a possibility of upsetting existing users, where a dialplan
    could run out of stack space where it had run fine before.  Alternatively,
    we could have allocated off the heap, but that is a larger change and would
    have increased the chance for instability introduced by this change.
    
    This is really solved starting in 1.6.0.11, as the use of an ast_str buffer
    allows an unlimited number of extensions (up to available memory).  We
    additionally create a new warning message when the buffer length is exceeded,
    permitting administrators to see an issue after the fact, whereas previously
    the list was silently truncated.
