Showstopper and regression against 5.0.24.
Previously, we ignored seek() errors (see Bug#22828) and let seek()s
against pipes fail. Now, since we check that a seek didn't fail,
and return without reading, this bug popped up.
This restores the behavior for file-ish objects that could never be
seek()ed.
mysys/mf_iocache.c:
If we detect early that the file is not tell()able, then we should
assume that it's also not seek()able and therefore we should never
set the (poorly named) "seek_not_done" flag so that we don't immedi-
ately try to seek() when reading later.
The problem was that tell() was returning -1, so when we read later,
we needlessly tried to seek to position (unsigned long) -1 .
Also, if we think we're supposed to seek to a position in a file and
the file is un-tell()able, then abort.

Thirty five seconds is entirely too short of a period to wait for a server
to exit. Instead, make a valliant effort to make sure it exits, and only
give up after a very long period (arbitrarily chosen as 15 minutes).
In addition, if we're being asked to restart the server, then don't try
to start again if trying to stop the server failed.

Bits higher than 2**31 were impossible to set on THD::options. It's

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.
