[WIP] Libsass 3.2.0

[chrinor2002]

An update to libsass 3.2.0. Currently this is beta, but the initial work has been done to bring the php module up to pay with the library. Once the official release comes out this should be able to be merged.

Warning! this contains the removal of the image_path. This is no longer available in libsass: sass/libsass#489

It is also worth mentioning sass/libsass#940. There is a "breaking" change that was introduced related to memory management. The general quick fix was to add a strdup() call before passing along the source. Without this there was a "pointer being freed was not allocated" error.

Looks like there is only one test still not passing:

parse_file_parses_file.diff:

003+   blah: "hello 4 world px bloon blah"; }
003-   blah: "hello 4 world px bloo\n blah"; }

scss:

blah: "hello #{2+2} world #{unit(23px)} #{'bloo\n'} blah";

Do we happen to know what sass-spec test that came from?

The test.scss comes from the original author who has since abandoned this. I have then run the same files against ruby sass before pushing it here in order to make sure that we generate the same code as ruby sass or, if we don't that we can be sure it's an issue in libsass itself (which it always was back then - the library was in horrible shape).

Current ruby sass produces the same output as you are seeing, so I would say we can just update the (nonesensical to begin with) test

Alright, assuming there is no other breaking issues before 3.2.0, we should be good to go once its released.

merging this now in preparation of the final release (which then will just be a submodule update).

Again, thanks a LOT for your contribution
