0fdbe24aaf Provide error message after failure to create large Sundials matrix 
If Sundials tries to create an excessively large matrix, it returns a null
pointer. To avoid a subsequent segfault, throw an exception which makes the
cause of the error clear.

WIP: Better error message for too-large Sundials matrix

TEMP: fixup for cvodes error messages

mode, the errors are shown as they occur.

state variables than the specified maximum number of error estimates to display.

0886de8650 Include CVodes error text in resulting CanteraErrors 
Failures in 'integrate' and 'advance' now include the error text provided by
CVodes directly, rather than just the numerical error code. This is especially
helpful in cases where the direct output from CVodes to stderr is lost
(e.g. when running from the Matlab GUI).

7b76e762d2 Fixed sensitivity calculation when using CVodesIntegrator::step 
Previously, the sensitivity coefficient matrix m_yS was being updated only when
the `integrate` method was used to advance the system. Now, the sensitivities
are updated when a coefficient is requested after taking a timestep, regardless
of the method used to advance the system.
