Prepare beta release 0.10.0beta1.

Make sure to pickle all attribute of Function (and FunctionMaker)

Alloc ops params

Use sha256 for config hash to be FIPS compliant and make Theano cache more forward compatible

Pickle/Unpickle trust_input. We use False (the default) for old pickle that don't have the information.

Fix missing scipy and warn that Theano will have a c++ compiler mandatory

[CRASH] Crash fix when we don't do scan(..., profile=True)

Convert the docstrings to comments in compile/tests

sync attribute added to theano function

Remove config.gpuarray.sync from Theano code.

Fix gh-6268. Crash fix when we don't do scan(..., profile=True), but we do theano.function(..., profile=True)

This reverts commit e62e923b.

We force the recompilation in this PR already. So keep the code base simpler.

Add in the keys the props of the nodes. To make the keys forward compatible in case we add new attribute, but forget to bump the c_code_cache_version number.
