Added support for network and fflush to decrease latency.

[Kixunil]

These changes allow users to stream video directly over network with lower latency (bypassing pipes and buffers). If file name has format tcp://host:port then TCP connection to host:port is opened. Similarly if udp:// is used, UDP packets with data are sent to host:port.

Would it be possible to use the same bracketing style as the rest of the code please (Allman).

Regularly calling fflush will reduce performance for the usual case (writing to sdcard) where we don't care about latency.

[JamesH65]

I'd suggest it would be worth putting the fflush as an optional parameter
just for those who need it..

Sorry to come back so late, I forgot about this PR. I fixed the braces and made optional switch to enable flushing. In case of other issues feel free to write me.

[Kixunil]

Sorry, I used tabs in vim. Fixed it.

[popcornmix]

Can you squash all commit to a single one and force push.
@JamesH65 @6by9 okay by you?

[Kixunil]

@popcornmix Done, is it OK?

[Kixunil]

Yeah, I prefer tabs and I'm very accustomed to using them. Sorry.

[JamesH65]

Using "f" as the short command line parameter conflicts with the preview -f
option - I'd suggest changing to -fl which I think is free. You need to
cross check with RaspiPreview.c, Raspistill/vid.c and RaspiCamControl.c to
find a 'spare' option.

Content looks fine to me other than James having picked up on the clash of -f in the option.

[Kixunil]

@JamesH65 I didn't know that options should be conflict-free across different tools. I just changed it to -fl, as you suggested.

[JamesH65]

They are not different tools, as things like RaspiPreview are used across
multiple tools. Hence the requirement to keep things unique.

@JamesH65 OK, thanks for explanation!
