[CinCV] gcc 4.4 issues

[Simeon Völkel]

Hello,

einar's repo doesn't compile anymore using gcc 4.4:

../../cinelerra/yuvstream.C: In member function 'int
YUVStream::open_write(const char*, char*)':
../../cinelerra/yuvstream.C:85: error: invalid conversion from 'const
char*' to 'char*'
make[3]: *** [yuvstream.o] Error 1

According to http://gcc.gnu.org/gcc-4.4/porting_to.html const-ness is now
more strictly handled.

The attached patch should resolve that problem in yuvstream.[hC].

Simeon
