Merge branch 'stefano_zampini/pcbddc-reusebddc'
* stefano_zampini/pcbddc-reusebddc:
PCBDDC: remove unneeded code to check nearnullspace
PCBDDC: remove trailing whitespaces from source
PCBDDC: solved compilation error with complex build
PCBDDC: introduce a new variable in PCBDDC data stucture to store the actual number of current vertices (corners with constraints with basis changed)
PCBDDC: make BtoNmap a member of bddc data struct (created once after PCISSetUp)
PCBDDC: check of dirichlet and neumann solvers is not needed if pcbddc->NullSpace is not present
PCBDDC: improved reuse of coarse matrix
PCBDDC: better management of primal space. Now a coarse numbering is computed if and only if the primal space has been really changed
PCBDDC: allow different customization of dirichlet and neumann boundary indices among successive linear solves
PCBDDC: now PCBDDC reuses part of its private data if NearNullSpace customization is changed between different linear solves
PCBDDC: local work vectors should be created only if new constraints are created and the relevant sizes are different
PCBDDC/PCIS: make vec4_D a member of pcis, not pcbddc
PCBDDC: Prepare for different primal spaces customization among different linear solves
PCBDDC: demand object destruction to setup routines for BDDCGraph and constraints
