It is just use for adding context to errors, but we have `addTrace` to
do that. Let the callers do that instead.
The callers doing so is a bit duplicated, yes, but this will get better
once `DerivationOptions` is included in `Derivation`.
The STSProfileCredentialsProviders allows to assume a specific IAM role
when accessing an S3 repository. Sometimes this is needed to obtain the
permissions to operate on the bucket.
Rather than "mounting" the store inside an empty virtual filesystem,
just return the store as a virtual filesystem. This is more modular.
(FWIW, it also supports two long term hopes of mind:
1. More capability-based Nix language mode. I dream of a "super pure
eval" where you can only use relative path literals (See #8738), and
any `fetchTree`-fetched stuff + the store are all disjoint (none is
mounted in another) file systems.
2. Windows, where the store dir may include drive letters, etc., and is
thus unsuitable to be the prefix of any `CanonPath`s.

Revert most of "Hack together a fix for the public headers"
- The `libmain` change is kept, and one more libmain change is made.
(Need to update Meson and Nix per the package alike).
- The S3 situation is fixed in a different way: the variable is public
now, used in the header, and fixed accordingly.
- Fix TODO for `HAVE_EMBEDDED_SANDBOX_SHELL`
This reverts commit 2b51250534.
Previously, when lock file contained invalid JSON nix reported a parser
error without specifying the file it came from.
This change adds flake.lock file path to the error message to avoid
confusion.
