documentation for PetscViewerASCIIOpen() and MatView() and VecView() was WRONG for use with a
viewer that comes from PETSC_COMM_SELF. The documentation mistakenly said that the output was independent for
each process when in fact the communicator of the viewer must match that of the object.

Add the possibility of writing HDF5 data in single precision

This commit adds the possibility for the user, at run-time,
select to write single precision data into the HDF5 file.
This is useful in many cases, as one often stop the (iterative)
solver when an approximate answer is found, thus not utilizing
full double precision. Using single precision for IO can then
save you half the disk space (or give you the possibility of
writeing twice the amount of data on the same space).

The HDF5 library takes care of the type conversion, hence the
required changes to the IO routines are very small.

ViennaCL: Fixes memory leak when destructing an aijviennacl matrix.
MatLoad_MPIDense() always allocated array space even if it was previously provided
Clarified lumping options for PCFieldSplitSchurPreType SELFP.
fixed up PetscInfo in GAMG
TSErrorWeightedNorm[2|Infinity]: API changes
MatLoad_SeqDense() always allocated new space for the data even if the user already provided it
Fixed DMCompositeGetAccessArray() to support readonly vectors
Fix obviously-wrong aspects of documentation on SNESVINEWTONRSLS and SNESVINEWTONSSLS.
fixed example to compile - demonstrates a bug
var name 'len' was F90 key word
For user provided Jacobian functions they should always assembly into the second matrix, the one from which the preconditioner is built because the first may be used as matrix-free with -snes_mf_operator
Suggest --with-64-bit-indices if users mistakenly use --with-64bit-indices
Fix configure logging of integer size.
missing underscore in #define of vecgetarrayread translation of fortran stub for VECGETARRAYREAD
updated test output files to reflect differences introduced previously in PCView output
-ksp_type preonly does not support -ksp_monitor_short so remove from test line to prevent extranious warning output
missing CHKERRQ; and ugly double declaration of ierr
Plex: Reorganized PlexPoint interface - Added DMPlexGetPointLocalField() and DMPlexGetPointGlobalField() - Now the DMPlexGetLocalOffset*_Private() functions return start and end - Uniformly use private functions

PETSc Vecs with a bs of 1, coming from a generic VecCreate() or DMCreateGlobalVector() with a DMDA
will NOT have an extra dimension attached to them in HDF5 files created with VecView() with HDF5 viewers,
to have that extra dimension even if the bs is on use either PetscViewerHDF5SetBaseDimension2() or
-viewer_hdf5_base_dimension2. Similarly to handle VecLoad() you need to set this value in the viewer if the
file has the extra dimension
