Create Haskell bindings for bcc

[nzhang-zh]

Start creating Haskell bindings for creating bpf module, loading function, clean up etc against bcc.

Start with providing minimum bindings to reproduce the hello_world.py with haskell.

Have a look at the Haskell BPF paper. I have that on my desk.

A side note on adding bcc dependency into cabal2nix --hpack based Haskell environment on nix. Turns out bcc is accessible from nix-shell if it is directly added to package.yaml via extra-libraries.

Something like

library:
  source-dirs: src
  exposed-modules:
    - Lib
  extra-libraries:
    bcc

The cabal.nix generated will then have bcc in its arguments set.

{ mkDerivation, base, bcc, c2hs, hpack, stdenv }:
mkDerivation {
    ...
}

And bcc need to be explicitly specified in default.nix when calling.

drv = haskellPackages.callPackage (import ./cabal.nix) { bcc=linuxPackages_4_18.bcc; };

I've mentioned this in the Haskell-Demo issues.
