ad403413c7 a ton of gzip changes, split up in compiled and 
run-tested pieces. Code was rather messy.
It's not a bug fix, more like code cleanup.

This is the first part.

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!

d6772501db tar: fix and sanitize handling of long filenames/linknames 
(GNU extensions 'K' and 'L').
We correctly handle them when untarring now, but unfortunately
we still don't use them when tarring! That stupid 100 char limit
is still there!
The biggest problem is that we don't support 'pax' tar format.
Linux kernel tarballs are in this format... shame
