general-purpose stream-handling tool similar to dd

cstream is a general-purpose stream-handling tool like UNIX' dd, usually used in commandline-constructed pipes.

Features:

 - Sane commandline switch syntax.
 - Exact throughput limiting, on the incoming side. Timing variance in
   previous reads are counterbalanced in the following reads.
 - Precise throughput reporting. Either at the end of the transmission
   or everytime SIGUSR1 is received. Quite useful to ask lengthy
   operations how much data has been transferred yet, i.e. when
   writing tapes. Reports are done in bytes/sec and if appropriate in
   KB/sec or MB/sec, where 1K = 1024.
 - SIGUSR2 causes a clean shutdown before EOF on input, timing
   information is displayed.
 - Build-in support to write its PID to a file, for painless sending of
   these signals.
 - Build-in support for fifos. Example usage is a 'pseudo-device',
   something that sinks or delivers data at an appropriate rate, but
   looks like a file, i.e. if you test soundcard software. See the
   manpage for examples.
 - Built-in data creation and sink, no more redirection of /dev/null
   and /dev/zero. These special devices speed varies greatly among
   operating systems, redirecting from it isn't appropriate
   benchmarking and a waste of resources anyway.
 - Accepts 'k', 'm' and 'g' character after number for "kilo, mega, giga"
   bytes for overall data size limit.
 - "gcc -Wall" clean source code, serious effort taken to avoid
   undefined behaviour in ANSI C or POSIX, except long long is
   required. Limiting and reporting works on data amounts > 4 GB.
