Attempt to fix the problem which causes cpuinfo.c to fail compilation on
MacIntel system (OSX/gcc4 on Intel):

utils/cpuinfo.c:44: error: PIC register '%ebx' clobbered in 'asm'

Need <stdlib.h> to avoid the error:
utils/cpuinfo.c:215: warning: incompatible implicit declaration of
built-in function 'exit'

Remove unused variable 'i';

tidy up the goofy whitespacing.

motionsearch_deint.c: In function 'motion_compensate':
motionsearch_deint.c:110: warning: unused variable 'v'
motionsearch_deint.c:110: warning: unused variable 'g'
motionsearch_deint.c:109: warning: unused variable 'min'
motionsearch_deint.c:105: warning: unused variable 'ds'

main.c: In function 'main':
main.c:136: warning: unused variable 'cpucap'

some improvements, some cleaning...
still a lot to do...

allow a YUV4MPEG2 header to appear midstream, as long as all the
characteristics of the new stream match the existing stream

yuvmedianfilter.c: In function 'filter_buffer':
yuvmedianfilter.c:522: warning: pointer targets in passing argument 6 of 'mean1' differ in signedness

Change the mean1() declaration to be 'int8_t' instead of 'char'.

Some systems lack fmin() so provide a compatibility function.
