Integrate H-Mat support via hmat-oss

This PR adds the support for H-Matrices in the coreblas kernels via the hmat-oss library (https://github.com/jeromerobert/hmat-oss)

@all: Please have a quick look to let me know if something seems wrong. I keep it as WIP for now until things have stabilized.

@all Please do a quick review and click the approve button if ok, or comment if any questions

How do you want to sync chameleon with the future evolutions of hmat-oss ? use a submodule ?

OK to make test-FEMBEM public. I pushed in it an update today merging most of rocio stuffs (except "dump the memory ratio tile by tile" -> do you want to keep it ?). There was also a commit (9eb2a6d5)in chameleon-hmat/chameleon.git to adapt to the latest evolution in hmat-oss CMakelists.txt (commit 31bcc3e), maybe you could take it before merging ?
