but only one of them would be affected by .skip-subtree
The "subtree" to be skipped here refers to all children of the

Having `prettyRes` in the execline script causes it to fail because of
the argv limit if your test suite is long enough. For the succeeding one
we can work around this by hashing it (since we only care that something
changes if the test suite changes), in the case of the failing one where
we want to print the results, we use runExecline's stdin mechanism.

This is generally useful for readTree users and should be part of

This is a move towards exposing several readTree-related features from
the library itself, in the future also including logic like 'gather'.
Note that this has a small functional change: In error messages of the
function, the notation for accessing Nix attributes is now used rather
than the Perforce-style `//` notation common in TVL.
For example, an error at `//web/tvl/logo` will produce `web.tvl.logo`
in the error message (which corresponds to the readTree attribute
itself).
This makes more sense for non-TVL consumers of readTree, as the
Perforce-style notation is custom to us specifically.

In order to make readTree import symlinked directories I've been looking
into how to detect if a symlink points to a directory (since this would
allow us to use symlinks for //nix/sparseTree). I've found a hack for
this:
symlinkPointsToDir = path: isSymlink path &&
builtins.pathExists (toString path + "/.")
Unfortunately it doesn't seem to be possible to distinguish whether the
symlink target does not exist or is a regular file.
Since it's possible, I thought might as well add this to
`pathType`. To make returning the extra information workable, I've
elected to use the attribute set layout used by `//nix/tag`. This
doesn't require us to depend anything (as opposed to yants), but gives
us pattern matching (via `nix.tag.match`) and also quite idiomatic
checking of pathTypes:
pathType ./foo ? file
(pathType ./foo).symlink or null == "symlink-directory"
Nonexistent paths are encoded like this:
pathType ./foo ? missing
Of course we can't use this in readTree (since it must be zero
dependency), but we can easily inline this hack at some point.

This change adds a new attribute to readTree nodes, `__readTreeChildren`
which is a list of attribute names added to this node by readTree.
This is then used by `gather` for `ci.targets` to avoid evaluating
attributes unnecessarily. Especially since Nix is not as lazy as we'd
like when determining types (i. e. child ? __readTree needs to force
`child` even when it's not an attribute set), evaluating attributes
unnecessarily is sometimes problematic.

CCL and SBCL create executables by dumping their image. As a
consequence, some part of the respective compiler is embedded in the
resulting executable which is executed and loads the image. For CCL and
SBCL this piece of software seems to unconditionally parse arguments
which can't be prevented since it happens before any lisp is loaded.
Luckily in both cases the parsing stops at `--`, so we can just pass
this via the wrapper — we just need to work around the problem that this
will of course be left in argv and confuse any later code. This can be
rectified by deleting everything prior to the first `--` in the global
argument list on startup in both cases.
In cases we do want to pass arguments to the image loader, we can use
the special NIX_BUILDLISP_LISP_ARGS environment variable which is
understood by the wrapper.
Note: This fix doesn't interfere with ECL since it is not using the
wrapper script at the moment.
Fixes b/136.

Instead of using a string to refer to an internal set defined in
buildLisp, we just expose the relevant sets (as nix.buildLisp.sbcl,
nix.buildLisp.ecl, …) and receive them as the `implementation`
argument directly. This has several advantages:
* It becomes easier to extend buildLisp, even for downstream users:
Since you can just pass your own set, there's nothing stopping you
from adding support for another implementation in a downstream
derivation without having to edit the buildLisp file in any way which
is great if you're using e. g. builtins.fetchGit to import it.
* Users can mess with the implementation set by changing out some parts
of it for customization purposes. Note that currently the sets use a
lot of self-references which aren't even bound by a fix-point, so to
make this work smoothly, we'd need to add some overriding mechanism.
* The buildLisp code becomes quite a bit clearer. Since we're now always
dealing with the implementation set, the confusing distinction between
`impl`, `impl.name` and `implementation` no longer exists. `impl` is
now exclusively an abbreviation of `implementation` (we could make
this more consistent in the future even).

Adds ECL as a second supported implementation, specifically a statically
linked ECL. This is interesting because we can create statically linked
binaries, but has a few drawbacks which doesn't make it generally
useful:
* Loading things is very slow: The statically linked ECL only has byte
compilation available, so when we do load things or use the REPL it is
significantly worse than with e. g. SBCL.
* We can't load shared objects via the FFI since ECL's dffi is not
available when linked statically. This means that as it stands, we
can't build a statically linked //web/panettone for example.
Since ECL is quite slow anyways, I think these drawbacks are worth it
since the biggest reason for using ECL would be to get a statically
linked binary. If we change our minds, it shouldn't be too hard to
provide ecl-static and ecl-dynamic as separate implementations.
ECL is LGPL and some libraries it uses as part of its runtime are as
well. I've outlined in the ecl-static overlay why this should be of no
concern in the context of depot even though we are statically linking.
Currently everything is building except projects that are using cffi to
load shared libaries which have gotten an appropriate
`badImplementations` entry. To get the rest building the following
changes were made:
* Anywhere a dependency on UIOP is expressed as `bundled "uiop"` we now
use `bundled "asdf"` for all implementations except SBCL. From my
testing, SBCL seems to be the only implementation to support using
`(require 'uiop)` to only load the UIOP package. Where both a
dependency on ASDF and UIOP exists, we just delete the UIOP one.
`(require 'asdf)` always causes UIOP to be available.
* Where appropriate only conditionally compile SBCL-specific code and
if any build the corresponding files for ECL.
* //lisp/klatre: Use the standard condition parse-error for all
implementations except SBCL in try-parse-integer.
* //3p/lisp/ironclad: disable SBCL assembly optimization hack for all
other platforms as it may interfere with compilation.
* //3p/lisp/trivial-mimes: prevent call to asdf function by substituting
it out of the source since it always errors out in ECL and we hardcode
the correct path elsewhere anyways.
As it stands ECL still suffers from a very weird problem which happens
when compiling postmodern and moptilities:

Concept is roughly:
* receive extra argument `implementation` that refers to the name of an
implementation or rather an attribute in an internal attribute set
telling buildLisp how to do certain build steps.
* We assume an implementation can execute lisp files as scripts and that
we can implement the following main tasks in lisp:
- Building a library (`genCompileLisp`)
- Building an executable (`genDumpLisp`)
- Loading a library dynamically (`genLoadLisp`)
Based on that we can implement:
- Running a test suite (`genTestLisp`)
- A REPL preloaded with a libraries and their dependencies (`lispWith`)
Additional attributes for implementing these parts genericly are
added as needed (`faslExt` and `runScript`).
* `genCompileLisp` no longer prints a shell script which concatenates
the individual FASLs. Instead it does the step previously done by the
shell script itself. In essence `genCompileLisp` now writes a lisp
script which compiles and installs the library to build.
This will allow us extra freedom for different implementations, e. g.
for ECL we'll want to build a object file archive additionally to fasl
files in order to be able to link proper executables.
* `genLoadLisp` and `genTestLisp` are almost generic (the former just
sometimes would need to use different file extensions), but we
integrate them into the implementation “API” to facilitate minor
tweaks we need to do like the `fasc` extension for ECL's native FASL
files.

We can be closed world, so let’s restrict the arguments to the subset
we need for now.
The existing override was wrong, in that `// args` would use the
arguments we already added, again. So instead of deliberating about
how to make this work right in all cases, we don’t need it, we trim
it.
