Use libnix as a prefix for all Nix libraries In particular "libutil" was always a problem because it collides with Glibc's libutil. Even if we install into $(libdir)/nix, the linker sometimes got confused (e.g. if a program links against libstore but not libutil, then ld would report undefined symbols in libstore because it was looking at Glibc's libutil).

StorePath: Rewrite in C++ On nix-env -qa -f '<nixpkgs>', this reduces maximum RSS by 20970 KiB and runtime by 0.8%. This is mostly because we're not parsing the hash part as a hash anymore (just validating that it consists of base-32 characters). Also, replace storePathToHash() by StorePath::hashPart().

Fix memory corruption caused by GC-invisible coroutine stacks Crucially this introduces BoehmGCStackAllocator, but it also adds a bunch of wiring to avoid making libutil depend on bdw-gc. Part of the solutions for #4178, #4200

Only link with libdl on Linux Linux is (as far as I know) the only mainstream operating system that requires linking with libdl for dlopen. On BSD, libdl doesn't exist, so on non-FreeBSD BSDs linking will currently fail. On macOS, it's apparently just a symlink to libSystem (macOS libc), presumably present for compatibility with things that assume Linux. So the right thing to do here is to only add -ldl on Linux, not to add it for everything that isn't FreeBSD.

ifeq ($(OS), Linux)
Don't try to link libdl on FreeBSD. There is no libdl on FreeBSD. Instead the symbols are included in libc.

Add importNative primop This can be used to import a dynamic shared object and return an arbitrary value, including new primops. This can be used both to test new primops without having to recompile nix every time, and to build specialized primops that probably don't belong upstream (e.g. a function that calls out to gpg to decrypt a nixops secret as-needed). The imported function should initialize the Value & as needed. A single import can define multiple values by creating an attrset or list, of course. An example initialization function might look like: extern "C" void initialize(nix::EvalState & state, nix::Value & v) { v.type = nix::tPrimOp; v.primOp = NEW nix::PrimOp(myFun, 1, state.symbols.create("myFun")); } Then `builtins.importNative ./example.so "initialize"` will evaluate to the primop defined in the myFun function.

Drop the dependency on libgc in libmain Instead, libexpr now depends on libgc. This means commands like nix-store that don't do any evaluation no longer require libgc.

# The dependency on libgc must be propagated (i.e. meaning that
# programs/libraries that use libexpr must explicitly pass -lgc),
# because inline functions in libexpr's header files call libgc.
