-------------------------------------------------+-------------------------
 Static analysis (coverity) detected that the system call fcntl in
 mythsystemunix.cpp did not check its return value.  This patch adds in
 that check.

 This patch also implements the more robust setting of the fd flags (get
 the current flags, or'ing in the NONBLOCK value, and then setting the
 flags).
 This is the "correct" way to set flags per the docs (even though in this
 case it is probably overkill).
