* jose/lapack-check:
configure: add a few checks for missing Lapack subroutines
See PR #761 on Bitbucket.

BuildSystem: Updated list of LAPACK routines to check for.

hypre: check if user specified hypre has HYPRE_BIGINT that is compatible with PetscInt

metis: check if user specified metis has IDXTYPEWIDTH value compatible with PetscInt

Merge branch 'maint'

configure: print a warning if wrong type gets used - for eg: --with-mkl_pardiso=~/local_opt/intel/mkl

Reported-by: Roland Richter <roland.richter@ntnu.no>

revert sources to dev
- reset PETSC_VERSION_RELEASE
- reset changes/dev.html
- enable cuda in configure

release: set v3.8 strings

Merge branch 'pr746/irinasok/feature-baijmkl/master'

* pr746/irinasok/feature-baijmkl/master:
Implementation of BAIJMKL matrix type similar to AIJMKL.
Supports MKL calls for MatMult (add and transposed).
In case if used MKL version does not support mkl_sparse_optimize() (MKL 11.2 and earlier) PETSc default kernels are used.
Test added on configuration step to check if used version of MKL supports column major layout with zero based indexing.
All released versions of MKL do not support such cross case and MatSeqBAIJMKL_create_mkl_handle() converts matrix arrays to one based indexing before passing them to mkl routines.

Added new matrix classes to include files
Added define MKL_SUPPORTS_BAIJ_ZERO_BASED to suuport different versions
of MKL (older verions support only one based indexing for column major
blocks in baij

Random123: added package

The website asks you to consent for the license, but registering your email address
is optional, so I did not put a _license warning in.

Add --boost-headers-only option so user can not build boost library and only install headers

'quad' -> '__float128'

parmetis: always build single precision (default) version
[we should be able to use single/double parmetis from any of single/double/quad petsc builds]

Merge remote-tracking branch 'origin/balay/fix-with-cuda'

Revert "Revert "Merge remote-tracking branch 'origin/balay/fix-with-cuda'""

This reverts commit 3aefdf506021f4cbf7fa49ea363acdb4288d4afb.

cuda: don't know how to access CUDAC from compilerOptions.py. Alternate fix is to remove this workaround (its for cuda 4.1 anyway)
