    These should use ast_strdup and should be checked for failure.

> During masquerade it is possible for the AST_JITTERBUFFER_FD to be cleared (set to -1).  This change adds a check when copying channel fd's to prevent clearing an FD with -1.  This seems to resolve the bad audio quality experienced after the masquerade.  When AST_JITTERBUFFER_FD was set to -1, this prevented the channel from polling that timer.  This caused RTP packets to be received late, and discarded.
