Fix PTHREAD_LIBS usage - needs to be @PTHREAD_LIBS@ rather than $PTHREAD_LIBS

fix warnings patch from fabian greffrath

Missing '}'

Forgot the last edit ;)

Patch from Fabian Greffrath for "build with LDFLAGS=-Wl, --as-needed". Not
needed on most systems but it doesn't appear to harm anything on OSX

Use extended family info for newer cpus (4 bit field could only go to 15)

Couple include files to get prototypes for strcmp and usleep

Fixed: mpeg2enc output bit rate exceeding maximum rate due to faulty
algorithm for self-tuning pass-2 reencoding. New algorithm implemented
that won't have this problem
Fixed: mpeg2enc use of uninitialised variable in pass-2 rate controller.
Fixed: mplex incorrect substream id for multiplexing for dvd authoring.

1) Document that $n (frame count) is no longer subsituted for. The author of
the program hard coded 0 for the value of '$n'.
2) DO NOT USE size_t if '-1' is going to be used as a sentinel! Something like
'if (jpegsize < 0) ...' does not work if jpegsize is size_t. Use ssize_t
instead!

Forgot to comment that the informational message about the input and output
rates needs to be printed BEFORE the '-r' value is clobbered. If -c is given
the program's logic copies the source frame rate over top of the -r value
before entering the conversion. Fix was to move the print statement out from
the conversion routine into the main program before the variable was overwritten
