Update bpftrace to the latest pre-release, with a real version number. The most notable change now is that bpftrace can use a stable version of the 'bcc' toolchain in order to build, meaning no more hacks are needed to clone the source code and fix up the build system, etc. This simplifies things greatly and removes the old bcc-source patch. Similarly, we can remove our custom gtests patch (which disabled the build) by just passing -DBUILD_TESTING=FALSE when running cmake. This was also added upstream recently. However, something does still need to be fixed, at a cost: bpftrace requires the kernel -dev package because it wants both objects and include directories (some files are only shipped in one or the other). Therefore, we remove the dependency on linuxHeaders and instead use kernel.dev as the sole input to the build. This is both a positive and a negative: the positive is that tools work without annoying fatal errors, and that the bpf toolchain is synchronized to the linuxPackages.kernel derivation it was built against. The downside is that the .dev expression is much heavier as a dependency, so bpftrace is now closer to 700mb in closure size. (This especially hurts across kernel upgrades requiring a whole new rebuild, especially if you have existing nixos generations that won't GC, etc.) We probably want to slim this down substantially in the future (and there may be a few ways to do that), but as this will probably also touch bcc, and as a first cut of the pre-releases, this is probably fine while we work out other kinks.

Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels https://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-19.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-19.03
For pull requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
