3376298b59 Stop tracking buffer size - it is a constant. 
Stop ignoring write errors.
Fix bugs in this line:
rc->buffer_size = read(rc->fd, RC_BUFFER, rc->buffer_size);
(a) should use safe_read()
(b) just ONE short read (e.g. 4 bytes) will make ALL future reads short!

We correctly handle them when untarring now, but unfortunately

is still there!
The biggest problem is that we don't support 'pax' tar format.
Linux kernel tarballs are in this format... shame
