Unfortunately, gitifyhg is slow for these one-shot pulls, mainly because hg
bookmarks and branches are not namespaced. Perhaps we can hack a
namespacing using the (perpetually unstable) Python API to make these fast.

I'm testing it now.

Can we also get rid of --with-c++-support?

I would start by deleting all occurrences of PETSC_USE_EXTERN_CXX (assume
it is always defined, but use defined(__cplusplus) for some include guards).

Then I would change all PETSC_EXTERN_C and PETSC_INTERN_C statements to
PETSC_EXTERN and PETSC_INTERN.

I don't think we can delete include/*.hh until Sieve is gone.
