moved PCTELESCOPE comment into users manual since no one will see the comment
message in makefile about hypre bugs causing test crashes
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
Force generateetags.py to use /usr/local/bin/ctags before using ctags because the ctags provided with Apple XCode gets confused by function usage in .tex files and does not make proper tags for TSSolve() and many many others
Optimized version of snes/examples/tutorials/ex1f.F produced incorrect results when lx_v() and lf_v() were declared as of dimension 1 with optimzed builds only. Cannot explain exactly why this happens but since we are using VecGetArray() from Fortran we are gambling with the compiler regardless
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 by using the option -pc_gamg_random_no_imaginary_part
added parallel tester for examples. Crude but it reduces a basic alltests on my laptop from 25 minutes to 7 1/2 minutes.
remove unneccessary if
fix the problem for ex9 which involves multiple TSSolve calls
shortened the time of several test examples
decrease dramatically the time used by several test examples that take more than a minute on may machine with debug mode
Some of the vectors created in MatNullSpaceCreateRigidBody() were not normalized to 1
fix strange PCTelescope struct name of P which caused duplicate symbol error on some systems cleanup use of PetscMalloc and PetscFree for telescope for modern PETSc standards replace semiredundat to telescope in makefile that runs test examples
SNESUpdateCheckJacobian: make relative norm output syntactically correct

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

Merge branch 'jed/mat-assembly-perf' of bitbucket:petsc/petsc

VecAssembly and MatAssembly now use a scalable exchange pattern based on
PetscCommBuildTwoSided. This feature can be controlled with the options

-vec_assembly_bts 0 or 1 (default 0)
-matstash_bts 0 or 1 (default 0)

The rationale is that the new implementation with scalable data
structures can be slightly slower than the old version at small process
counts. The default here could be changed to depend on the process
count (leading to possibly-confusing scaling performance diagnostics) or
the implementation could learn to take a fast path.

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.

MatShift_MPI/SeqXAIJ() could hang if some processes had no entries on a process while others had entries
because some processes would attempt a parallel preallocation and the others would not.

Fixed

MatShift_MPI/SeqXAIJ() could hang if some processes had no entries on a process while others had entries
because some processes would attempt a parallel preallocation and the others would not.

Fixed by first checking if no preallocation was done, and if not doing. Otherwise preallocation is only done
if approprate by each process on the diagonal block portion of the matrix, thus not requiring all processes
that share the matrix to call the parallel preallocation routine
