Closes #64

@bstellato Any idea why
https://github.com/oxfordcontrol/OSQP.jl/blob/d36d3e0fc8b07f0a5771d14763930eeb3acc7822/src/interface.jl#L445-L446
is failing on 32 bits ?

With what options are the binaries compiled? I see

https://github.com/oxfordcontrol/osqp/blob/d7eeb245d5b7f0195bfc35b6cb71f4570d7ca18b/include/osqp.h#L419-L420

and

https://github.com/oxfordcontrol/osqp/blob/d7eeb245d5b7f0195bfc35b6cb71f4570d7ca18b/include/glob_opts.h#L73-L78

and

https://github.com/oxfordcontrol/osqp/blob/657a3b117320c4f8ecb57e27011e75e63f61ce4d/include/glob_opts.h#L81-L85

which means that there are a couple of options for what c_int and c_float are.

[bstellato]

We compile the solver with default options for the binaries (see here for windows). Default options are: DLONG=ON and DFLOAT=OFF.

As @tkoolen mentioned, we define c_int and c_float here according to the option.

In OSQP.jl we map the short/long int C type to the julia one in here. This made it work for 32bit until now. Did anything in Julia change to make it fail? Our binary build system did not change since last OSQP.jl release.

I am merging to allow to check that OSQP master work with MOI master (see https://travis-ci.com/blegat/SolverTests/jobs/249637424) before releasing MOI v0.9.6. I am opening a separate issue about the 32-bit issue.
