UNIX: do not automatically restart syscalls on SIGINTHEADmaster-fmsbw-cimaster
* signal() sets SA_RESTART by default.
* Some syscalls can theoretically block indefinitely.
Even opening a special file could result in an indefinitely
blocking operation, that should be interruptible.
You must still poll teco_interrupted in these read() loops of course.
* Also makes sure that clipboard operations are interruptible
even if $SCITECO_CLIPBOARD_GET blocks.
Although I couldn't provoke problems in practice,
I did observe hangs with xclip on Wayland on Linux,
that could only be resolved by manually killing xclip.
