have to turn off stack SAWs serving before turning off SAWs
some silly python code badly processing SAWs json

added -saws_https and -saws_port

updated to latest SAWs API

added support for -saws_log

updated to new /dir1/dir2/variablename scheme for SAWs

updated PETSc to use a hierarchy of SAWs directories, doesn't work properly

update for latest SAWs

bugfix for build error on cygwin

better error display

trivial cleanup

update PetscSubcommSetTypeGeneral() - rm input duprank

cleanup

add PetscSubcommSetFromOptions(); PCRedundant can swith to PETSC_SUBCOMM_CONTIGUOUS at runtime

implement MatGetRedundantMatrix for psubcomm_type CONTIGUOUS; rename MatGetRedundantMatrix_MPIAIJ_interlaced to MatGetRedundantMatrix_MPIAIJ_psubcomm

add PetscSubcommView()

rm mlocal_red from MatGetRedundantMatrix()
set defaults in PetscSubcommCreate()

add 'type' to struct _n_PetscSubcomm

converted uAMS usage to SAWs usage; starts server but cannot see any published directories

Adding PREPROCESSOR directives to protect ELL and HYB storage formats.

I've added preprocessor directives around all code using the cusparse
hybrid (or ellpack) format to only build when CUDA 4.2 or beyond is
being used. I've also changed the documentation in a few places to
reflect this. In a few places, protections were required for CUDA
5.0 (hyb2csr conversion and in the stream creation in veccusp.cu).

Also adding code to the init.c that 1) checks cuda error codes and
2) sets the device flags so that memory can be registered as paged-
locked via : cudaSetDeviceFlags(cudaDeviceMapHost). This should be
valid for all 1.3 devices and later. Moreover, these changes allow
multiple MPI threads to work on 1 GPU using cuda streams in a thread
safe manner.

* maint:
doc: add petsctime.h to SOURCEH (fixes missing docs)
Increase patchlevel to 3.4.2
ABI compatibility for debug and optimized builds

completed allowing generating graphics with Xvfb, works with AMS

need to start AMS server after Xvfb or else Xvfb cannot load keyboading mapping, no idea why.
