When only one row was present, the subtraction of nearly the same number
resulted in catastropic cancellation, introducing an error in the
VARIANCE calculation near 1e-15. That was sqrt()ed to get STDDEV, the
error was escallated to near 1e-8.
The simple fix of testing for a row count of 1 and forcing that to yield
0.0 is insufficient, as two rows of the same value should also have a
variance of 0.0, yet the error would be about the same.
So, this patch changes the formula that computes the VARIANCE to be one
that is not subject to catastrophic cancellation.
In addition, it now uses only (faster-than-decimal) floating point numbers
to calculate, and renders that to other types on demand.

sql/item_sum.cc:
Serg's suggestion: Force all VARIANCE calculations to be done with floating-
point types. It's faster, and the SQL standard says we may implement these
functions any way we want.
Additionally, use a form of variance calculation that is not subject to
catastrophic cancellation.

- Don't call SSL_shutdown a second time
vio/viossl.c:
SSL_shutdown might return 0 indicating that it should be called once
again for a graceful shutdown. Since the socket are going to be closed
anyway ther is no need for the second call.
