To: notmuch
The main goal is to support gzipped output for future internal
calls (e.g. from notmuch-new) to notmuch_database_dump.
The additional dependency is not very heavy since xapian already pulls
in zlib.

The idea is to provide a more or less drop in replacement for readline
to read from zlib/gzip streams. Take the opportunity to replace
malloc with talloc.

We rely completely on zlib to do the right thing in detecting gzipped
input. Since our dump format is chosen to be 7 bit ascii, this should
be fine.
