PCBDDC: improved code for local corrections and coarse basis functions setup
No new functionalities have been introduced with the commit.
Main changes are:
- VecType is now inferred by the type of the PCIS working vector vec1_N
- Working mat M1 now computed using MatMatSolve
- Use of PetscMemcpy whenever possible
- Replacing "VecGetArray/set values directly into array" by VecSetValues/VecAssembly calls
- Use of VecGetArrayRead instead of VecGetArray
- Optimized use of stacked variables
- Small changes in order to adhere to developers guidelines

PCGAMG: Always rebuild coarse Mat the first time
The old conditional assumed that, if (!pc_gamg->repart), then the only coarse
matrix that needs to be rebuilt from scratch is on level 0. If the user has
changed pc_gamg->min_eq_proc, matrices higher in the hierarchy may also need to
be rebuilt from scratch.
