Flake follows: resolve all follows to absolute 
It's not possible in general to know in computeLocks, relative to
which path the follows was intended to be. So, we always resolve
follows to their absolute states when we encounter them (which can
either be in parseFlakeInput or computeLocks' fake input population).

pennae fd5aa6ee3e allocate a GC root value for the Value cache pointer 
keeping it as a simple data member means it won't be scanned by the GC, so
eventually the GC will collect a cache that is still referenced (resulting in
use-after-free of cache elements).

Fix exception handling around realisePath() 
This no longer worked correctly because 'path' is uninitialised when
an exception occurs, leading to errors like

       … while importing ''

       at /nix/store/rrzz5b1pshvzh1437ac9nkl06br81lkv-source/flake.nix:352:13:

So move the adding of the error context into realisePath().

John Ericson 5ee937523d Add back copyClosure for plain StorePaths 
This was removed in 2e199673a5 when
`copyPath` transitioned to use `RealisedPath`. But then in
e9848beca7 we added it back just for
`realisedPath`.

I think it is a good utility function --- one can easily imagine it
becoming optimized in the future, and copying paths *violating* the
closure is a very niche feature.

So if we have `copyPaths` for both sorts of paths, I think we should
have `copyClosure` for both sorts too.

Robert Hensing dec7748119 Replace withBuffer by boost small_vector 
Although this will leave gaps in the stack, the performance impact
of those should be insignificant and we get a simpler solution
this way.

Robert Hensing d038a67bd3 Fix segfault or stack overflow caused by large derivation fields 
This removes a dynamic stack allocation, making the derivation
unparsing logic robust against overflows when large strings are
added to a derivation.
Overflow behavior depends on the platform and stack configuration.

For instance, x86_64-linux/glibc behaves as (somewhat) expected:

$ (ulimit -s 20000; nix-instantiate tests/lang/eval-okay-big-derivation-attr.nix)
error: stack overflow (possible infinite recursion)

$ (ulimit -s 40000; nix-instantiate tests/lang/eval-okay-big-derivation-attr.nix)
error: expression does not evaluate to a derivation (or a set or list of those)

However, on aarch64-darwin:

$ nix-instantiate big-attr.nix                                                                                                                                                                                                                                                       ~
zsh: segmentation fault  nix-instantiate big-attr.nix

This indicates a slight flaw in the single stack protection page
approach that is not encountered with normal stack frames.

regnat dd7c2e0695 Make nix why-depends quieter by default 
Unless `--precise` is passed, make `nix why-depends` only show the
dependencies between the store paths, without introspecting them to
find the actual references.

This also makes it ~3x faster
