Merge in Barry's fix to synchonized print out of plex objects into

* master: (31 commits)
fix %nd for plex printf that should be %nD
PGI compiler requires cast to char* of this array for some reason
Incorrect use of %d for %D in viewing of PetscSection
update output for suitesparse examples with new KSP view data
changed boomeramg advanced smoother output files to use short format so there are less differences with different systems
fix some issues with PetscViewerFlush() and PetscViewerASCIIPushSynchronized() within the plex object viewing
incorrectly used stride value instead of local size in check that ISSTRIDE has same layout as columns of matrix
try using int(w) for Fortran case to integer instead of int(w,integer) since the latter failed on most systems claiming integer was not a constant. Very unclear to me what that second argument is suppose to be
SNES function evaluations were not counted for certain Jacobian computations
nightlybuilds: fix vec/ex7,ex7f link issue by using the correct LIBS option

nightlybuilds: arch-linux-complex-gcov -> arch-linux-cmplx-gcov to be consistant with other config tests
add __float128 data file neeed by test example 10 otherwise test example crashes with --with-precision=__float128 builds
cast fortran integer that may be 64bit with int() to prevent compiler warning about Warning: Possible change of value in conversion from INTEGER(8) to INTEGER(4) at (1)
removed unneeded definition of Sqr in example since PetscSqr should be used, and was in other parts of the same example!
nightlybuilds: run 'git gc' in the build clones
opensolaris: use 'FFLAGS=-ftrap=%none' this way fortran examples on solaris do not crash in lapack during 'div by zero' Also use the updated path to mpich
when I swapped the role of coulping and rest in fieldsplit I missed a place
cannot use PetscMalloc2() on arrays that will be freed as two seperate arrays

PGI compiler cannot handle [restrict] usage therefor disable restrict for PGI compiler Fix ex48.c to use PETSc standard way of marking restrict
PETSC_UNUSED must occur before the typename. With PGI compilers they error if it is after the type name
on solaris in TSAdaptChoose_Basic() negative root for zero could produce -infinity thus causing time step to be decreased even though the error estimate was zero
MatGetSchurComplement: revert test from LUMP back to DIAG and update output
there are no tests for opencl or viennacl so prevent warning message: make[2]: *** No rule to make target `testexamples_OPENCL', needed by `tree'. Stop. make[2]: *** No rule to make target `testexamples_VIENNACL', needed by `tree'. Stop.
incorrect initial conditions function that could produce floating point exception value (and does on windows) due to squareroot of non-negative number
forgot to fix rule for building ex194
move ex193.c to ex194 because someone else created a 193
remove outdate manual page comment
add missing VecRestoreArray()

missing restore array in example
formating for print statements of test example with __float128 precision
fix example for __float128 precision by using PETSc math macros and casting PetscReal in print statements
remove Tao example custom monitor that produced different results for __float128 precision
all PETSc built in monitors require a valid PetscViewer, NULL is not acceptable
PETSc built in monitors always require viewers to be passed in, no longer support a NULL viewer
use tigher haptol for minres for quad precision because otherwise false positive of indefinite matrix appeared in example

Better to use the proper error handling version of PetscViewerASCIIGetStdout() instead of PETSC_VIEWER_STDOUT_()
Generate a very useful error message if PetscLogView(), PetscLogEventGetPerfInfo() or PetscLogEventGetFlops() is called with a preceeding call to PetscLogBegin() and friends (also -log_summary which triggers a PetscLogBegin())

Merge branch 'barry/fix-nonew-notcollective/maint' into jed/mat-assembly-perf

Jed this fucking 6+ month running thing in next that is not in master is a royal fucking pain in the ass and
an abuse of git. I think it is not justified to ever have anything in next for more than a few weeks at most.
Either take it out of next if it is broken or put it in master if it is not broken. Hanging around in next but
not master for ever is not a good policy.
