[PATCH] Compressed streams

Hi everyone,

I was working on getting compressed text base support into svn, and I
thought a good first step would be to add compressed stream
support. So this patch adds a single function, svn_stream_compressed,
that wraps around an existing stream and compresses/decompresses all
the data read and written to it.

I understand that there's a feature freeze right now, but this code
doesn't really touch any other code, and is by default is disabled. To
enable it you need to pass a new --with-zlib switch to
./configure. There's also a test inside to exercise the code.

I think this code could be useful above and beyond my pet project of
compressing text-base. BTW, is there any chance of that sort of code
getting in before 1.0?
