Bump shared object version to 7

Almost certainly the ABI is binary incompatible for the 4.5.5 -> 4.5.6
transition, but we didn't think of handling the issue at the time.
So we can do so now.

added mdrun check for Verlet+perturbed atoms

Currently the Verlet scheme does not support perturbed atoms.
This will be implemented soon.

Fixes #1183 PBC bug in g_mindist

Fixes minimum size of the box if triclinic when checking
the periodic image distance.

Added install guide section for BLAS/LAPACK

Fixes #1186

corrected grompp rvdw charge-group radii check

The grompp note for charge-group radii larger than the buffer size
for VdW interactions only checked for rlist, not rlistlong.
Fixes #1164

made PME work with a mix of 1 and more threads

Using a mix of 1 and more OpenMP threads on different MPI ranks
would make mdrun terminate with an MPI error.

corrected log file wall time breakdown

The recent commit 873b9854 doubled the wall times in the breakdown
table in the log file when not using separate PME nodes.
Note that this didn't affect cycle count or total timing prints.
Fixes #1210

removed x86 specifics from nbnxn SIMD kernels

All x86 specific preprossing and SIMD intrinsics in
nbxn_kernel_simd_???_outer/inner.h have been replaced by generic SIMD
macro code. Exclusion masks are now loaded iso set and the treatment
is the same for most setups and can use only floating point intrinsics.
Moved half-width SIMD from gmx_simd_macros.h to two 2xnn .h files.
Half-width load macros now take the output as an argument,
in preparation for Intel MIC SIMD instrinsics.
Replaced _SSE suffixes by _S in the abovementioned files.

Fix bug in selection subexpression handling.

Did not work correctly if
1. a static expression was passed to a SPAR_ATOMVAL parameter,
2. other parameters to the same selection method were dynamic
   (so that the expression would not be completely eliminated during
   compilation), and
3. the evaluation group of the SEL_EXPRESSION element was dynamic
   (so that the SPAR_ATOMVAL expression could be evaluated for a
   different group during evaluation and compilation).
In this case, the static atom-valued parameter got evaluated during
compilation for the maximal evaluation group and replaced by a constant.
During evaluation, if the evaluation group was smaller, the values for
that expression were no longer correct.
See #1216 for what kinds of concrete selections this applies to.

Fixes #1216.

Fix another bug in selection subexpression handling.

In this case, it did not work correctly if a variable with a dynamic
value was used both
1. in a boolean expression such that its evaluation group was not known
   in advance, and
2. in a context where it was always evaluated for all atoms (either as
   a selection, or as a parameter to a selection method),
and additionally the latter context appeared later in the selection set.
The initialization of the SEL_CDATA_STATICEVAL flag has a dependency on
SEL_CDATA_FULLEVAL flag, and they were not initialized in the correct
sequence in the above case.

Fixes #1219.

improved load balancing with Verlet cut-off scheme

With the Verlet scheme the force calculation order is now like group:
non-bonded, bonded, PME
The non-bonded were done after PME, which prevented load balancing,
unless separate PME nodes were used.
