PCBDDC: added API for the specification of primal vertices in global ordering

propagate info on primal vertices to coarser levels when using the benign subspace trick (still need to be improved)

PCASM: For multiplicative, update the residual after each block
- The former stuff was just completely wrong

PCASM: For multiplicative, we need structures at the process level instead of just the block
- You need the process A to update the residual for other blocks

clarify the meaning of the terms used in the PCFIELDSPLIT Schur complement preconditioner.

Merge branch 'pr352/dmay/pctelescope/master'

moved PCTELESCOPE comment into users manual since no one will see the comment

remove use of some unitialized variables, remove use of "dummy" entries in Vec and IS since Dave May thought they could
not be of size zero. Now three telescope tests give no valgrind errors

code sent unitialized data via MPI
and allocated too large space for creating indices

make the PetscRandom object used in GAMG to be a public object that can be controlled via the
options database.
This allows the same example to produce the same results with real and complex numbers

PCBDDC: fixes for multiple PCSetUp calls using the benign trick

MatMUMPS: added API to set info on Schur complement using MUMPS convention

When A is just symmetric and we eliminate all the dofs accounting for the negative eigenvalues, S is positive
Like P2/P0 St

PCBDDC: added MatSeqAIJCompress to remove zero entries from SeqAIJ matrices

this is very very useful when changing the local basis with a PtAP operation, which does not care about possible zero entr

Making an even bigger mess, I cannot explain why this is not in the branch

hypre vecinterpvariant can only be 1 to 3

Merge branch 'pr352/dmay/pctelescope/master' of bitbucket.org:petsc/petsc into pr352/dmay/pctelescope/master

fixes for non-portable code, unused variables, uninitialized variables etc

c89: compile fixes

renamed semiredundant files to telescope

rename SemiRedundant Telescope
