if -log_summary is used then turn on cuda synchronized because too many people will screw up and get the wrong idea.

Make PetscOptionsGetString ensure that the result is NULL terminated, update uses.

The former usage sometimes passed len-1 and sometimes len
(inconsistently). Unfortunately, even using a shorter value does not
guarantee that the string is NULL terminated (because strncpy does not
terminate if the source string is longer than len). Since both uses
were incorrect in the presence of overflow, this patch chooses to
specify the length of the buffer rather than the maximum number of
non-NULL characters.

Factor out command-line options, arrange so -skip_petscrc works from the command line.

Processes command-line options twice, once before petscrc so that
-skip_petscrc can be observed, again after so that the command line
takes precedence over files. This is excessive, it is only necessary to
check for -skip_petscrc, but it's simpler to do it all twice.
