  Removed ADIOS1 engine's fixed -1 skew to timesteps as now both versions handle them the same way. This fixes the heat transfer example with the adios1 engine.

Removed ADIOS1 engine's fixed -1 skew to timesteps as now both versions handle them the same way. This fixes the heat transfer example with the adios1 engine.

Issue #363 BPFileReader BeginStep return

BeginStep shouldn't return EndOfStream status after reading last step.

Heat transfer example working as expected.
Tests modified.

Enable and Test writing Attributes in Fortran bindings

Each string in a string_array is limited to 256 in C and Fortran
bindings.

* release:
  Fix warnings from python and GNU headers.

Fix warnings from python and GNU headers.

Due to some squireliness of how python headers work, we need to include
any python binding headers first, before any C library headers.  This is
contrary to the projects coding and style guidelines but necessary
since python.h will otherwise re-define core system feature macros.
