Use cythonize for build
State: closed

Discussed back in #18089.  This builds OK locally, we'll see about the CI...

- Makes `util` a module instead of a stub.
- Renames io/sas/_sas.pyx --> io/sas/sas.pyx, otherwise a warning is produced at compile-time and an error is raised at import-time.

Hello @jbrockmendel! Thanks for updating the PR.





Cheers ! There are no PEP8 issues in this Pull Request. :beers: 

##### Comment last updated on February 06, 2018 at 06:47 Hours UTC
It looks like the CI errors are occurring in builds with cython pinned to 0.24.0.  The un-pinned builds are using 0.27.3 and passing.  Running locally it looks like 0.25.0 still breaks, but 0.26.0 works.
@gfyoung any idea what the timeline is for bumping the cython specs?  This is going nowhere until that happens, so may be closable.
@jbrockmendel : Not my call unfortunately.  Let's ping @jreback about this.
we changed this dep to 0.23 in pandas 0.20.1
It looks like implementing tslibs.util is a/the fix for the older cythons.
looks good. going to need a perf check. might want to put the util changes in a separate PR? 
Ran the whole asv suite a few times overnight.  
Usual melange
 A few things took a hit, see next comment.  First for just timeseries:

Going through looking for asv entries that show up repeatedly:

`timeseries.DatetimeIndex.time_add_timedelta('dst')` is pretty consistently showing up around 1.4x 
`timeseries.AsOf.time_asof('Series')` 0.85x
`timeseries.InferFreq.time_infer_freq(None)` 1.3x
`timeseries.InferFreq.time_infer_freq('D')` 1.3x

A whole mess of `time_add_offset(...)` in the 1.3-1.5x range

stopping the search here.  This is more change than I'm comfortable with; I'll try to track down the source.  Let's stick a pin in this for now.
