remove PETSC_DESIRE_COMPLEX and instead include complex with petscmath.h UNLESS PETSC_SKIP_COMPLEX is set (for SSL includes currently)

Merge branch 'barry/fix-complex-petscmath'

allow complex numbers to be used from both C and C++ (when supported)
not only the language PETSc was built with

defined MPIU___COMPLEX128 for clanguage=cxx so libraries build with that case for __float128

allow precision==__float128 to compile with clanguage=c++
requires extern statement for MPIU___COMPLEX128

gfortran: remove 132 char limit from f90 free-form
SNES: Set up matrix-free *after* copying the user Jacobian to snes->pc
DMPlex-Gmsh: Use trueNumCells when building the coordinate section
Sys: Got guard logic reversed
Sys: The #define guard for PetscMalloc*() must match the one for PetscFree*()
PetscFV: I hate fucking complex
removed ltog scatter from DMDA since functionality can be obtained with gtol scatter and less memory
fix test of DMLocalToGlobalBegin/End and add actual test cases
improve object memory logging for DA, ISLocalToGlobal and ISBLOCK
lower high water mark of constructing parallel scatter by allocating only as much room in svalues as needed
owner in VecScatter construction is the rank, therefor can use PetscMPIInt to hold it do not PetscInt
another reuse of allocated array in 2d/3d DMDA create
improved high water mark of DMDASetups by implementing and using PETSC_USE_POINTER for ISCreateBlock()
PetscFV: Another complex fix
DMPlex+TS: Fixing types
ISIdentity() was wrong for block IS! Indices are NOT scaled by bs
PetscFV: Straighten out complex types
TS ex11: Fix casts and remove unused variable

Merge branch 'master' into knepley/feature-plex-hdf5-parallel-load

* master: (125 commits)
since PETSc cannot view factored matrices, generate an error rather than display the wrong stuff (this was really bad)
outdated example that doesn't match coding style removed and buggy
petscversion.h: workaround ifort -cpp lack of referential transparency
configure: ignore AR, MAKEFLAGS [if set in env]
incorrect first entry in array being zeroed in example
sizeof.c: remove dependence on petsc [and fix syntax error]
nightlybuilds: use consistant PETSC_ARCH, machine names
TS: Allow viewing of TS solutions
DMPlex: Fix comparison for complex
change MPIVersion streams to use MPI_Wtime() to be portable to Windows do not use scalar square root on real number; it upsets Microsoft
cannot use I in PETSc code because in complex it sometimes represents imaginary number cannot pass PetscScalar * to VecNorm()
in dashboard don't warn about SSL and BOI deprecated
TS ex11: Fixed output formatting
Doc+DMPlex: Added function documentation for some refinement functions
streams: translate code from 'bash' to 'sh' [fix freebsd]
barry is an idiot who doesn't have a clue as to what he is doing (and git's unfriendlyness doesn't help matters)
don't list examples under C that don't work with complex!
forgotten output file
removed valgrind warning about sending uninitialized data
nightly builds ignore unrecognized pragma and .c file as C++ code

Microsoft C++ compiler needs extra care with complex numbers and casting
DMPlex: C++ has fucking namespaces, use them assholes
Field has 3 components therefor need to initialize three components, Microsoft C compiler demands it
DMPlex ex3: Added interpolation test - Only works for 2D simplices - Shows the restriction only gets constants right - Other small cleanup
DMPlex ex3: Change to interpolated meshes by default
DMPlex: Fix interpolation of multicomponent fields
DM: Fix reference counting in DMSetField()
DMPlex: Fix interpolation scaling

MatCreateTranspose: fix for lazy block size
mpich: use latest mpich tarball with gcov but use '--enable-coverage' mpich configure option.
configure: add FC_DEFINE_FLAG to petscvariables
added a citation for pounders, Stefan finally came through
update to latest netcdf fixes bug that did not allow building on recent Mac OS X
DMPlex: Fixes for CGNS - Fixed loop bounds since CGNS uses closed intervals - Bug with mixed cell types - Typo with coordinates
final updates from nightly tests
fix for countcfunction
removed outdated docs and comments on MatStructure usage removed SAME_PRECONDITIONER since no longer used removed unneed use of MatStructure in Schur complement matrix
removed MatStructure arguments from Tao
fixes for Sundials and fun3d cannot use MPIU_SUM for integer arrays
inplace ILU factorization must update state of inplace matrix to prevent infinite recursion of updating PC
fixes for BDDC by the way not having BDDC always in the testing is going to lead to trouble
the compute Jacobian functions for SNES and TS now do not take a MatStructure flag
KSPSetOperators() no longer has the MatStructure argument. The Mat objects now track that information themselves. Use KPS/PCSetReusePreconditioner() to prevent the recomputation of the preconditioner if the operator changed in the way that SAME_PRECONDITIONER did with KSPSetOperators()
tracks when Mat's have a change in nonzero structure this information can be used by PC to determine how preconditioners must be rebuilt currently only does an error check if the user said same nonzero pattern but actually changed the pattern
completed cleanup of removal of matrix pointers to compute jacobian routines
makefile: Added 'make includegraph' to create an inclusion dependency graph.
