Subject: [PATCH] setup.py: Fallback to use the system hiredis library.

Fixes #158 fully, including using a system-prodived hiredis.

When the hiredis git submodule hasn't been initialized, print a
message about it, and attempt to link against the a system-provided
hiredis library instead.

* setup.py (is_hiredis_bundled): New procedure.
(get_hiredis_bundled_sources): Likewise.  Print a message when
bundled_hiredis_sources is empty.
(get_sources): Adjust to use the above procedure.
(get_linker_args): Add -lhiredis when the bundled hiredis is not used.
