Make scm_c_read use caller buffer only for unbuffered ports.
We recently modified scm_c_read so that it temporarily swaps the caller's buffer with the port's normal read buffer, in order to improve performance in the case where the port is unbuffered (which actually means having a single-byte buffer) - but we implemented the swap in the buffered case too. The latter turns out to be a bad idea - because it means that the C code of a custom port implementation cannot rely on a port's buffer always being the same as when it was first set up - and so this commit reverts that. The buffer swapping trick now applies to unbuffered ports only. * libguile/ports.c (scm_c_read): Only do swapping of port and caller buffer for unbuffered ports.
