Do PETSc have an equivalent API call for every option you can set
using options database?

But they are generic... I would love to to have a
{KSP|PC|SNES|TS}SetOptions() to pass name,value pairs of options...
Right now, every time I need it, I have to play with the GLOBAL
options database.
Think about MPI_Info ... Without it, the MPI API should be far more
complex for very little to gain... IMHO, your "ALWAYS" is a bit
strong :-)
