* dvblast.c: Fix segfault with buffer overflow and -d option (thanks testking !) * ALL: Fix trailing whitespaces/tabs.

We're in non-blocking mode, so the kernel will deliver less than 50
automatically. Note: one DMA cycle might provide upto 350 TS packets
(64 kByte)

Migrate network code to use sockaddr_in instead of in_addr_t in readiness for addition of IPv6 support

This attemps at lowering the latency, at the expense of a slightly
raised CPU consumption. Please yell if you're not OK.

* udp.c: New input for DVBlast : UDP instead of linux-dvb (-D). * ALL: Virtualize the input functions to allow multiple input modules.

Include version info in dvblast and dvblastctl console output. Suggestion and initial patch (reworked) by Adrien Grand.
