This was due to a subtle mistake in the new code in
https://github.com/erlang/rebar3/pull/2322 which optimized the search
behaviour of files not found by EPP. The patch mistakenly always kept
the top-level src/ directory for an app even if it did a lookup in
recursive ones.
This patch tracks and maintains the proper subdirectory hierarchy. To
keep performance adequate, the lists:keyfind/3 function is used, which
is also now a NIF to the same extent as lists:member/2; manual lookups
would likely end up reducing performance, particularly in deep
hierarchies.
A test case has been added to track the regression.

Instead of sequentially running *.erl (or any other) files
one-by-one, spawn a separate process, in a scatter-gather way,
then wait for all processes to complete.
Combined with the previous change it introduces a significant
speed-up for large repositories, up to a number of cores that
the host has.
rebar3 would crash if the option `{keep_logs, N}` was present and
there were more than N run directories in the log dir, so if the
option is found we keep the N-1 newest directories and delete the
rest.
While we are at it, as this should fix the crash, let's limit the
number of logs runs to keep from test runs in rebar3 to 5.
this fixes the issue where using 'rebar3 plugins upgrade P'
would result in a plugin's .app file having an empty
modules list. The code this replaces hadn't been touched
since rebar3 3.0.0-beta.3 and a lot of improvements have
gone into dep handling and the compiler since then. This
change should take advantage of those changes.
This patch contains two behaviour changes and reasserts other behaviours
that now line things up with user and documentation expectations:
1. The src directories remain recursive. We turned it on by accident at
some point in the past and now people rely on it, so we're stuck with
it. However a new test ensures that the feature can be turned off
on-demand as documented on the website.
2. The test directories are no longer recursive by default. The fix is
done by properly fixing how rebar3.erl does its feature injection by
mandating the default value there.
I'm somewhat nervous that this change could negatively impact some
users and older compiler module versions, but if users stick to the
rebar_dir interface, everything should keep working transparently.
3. The test directories' configuration is no longer silently dropped.
Due to how rebar3.erl injected test state without looking for what
the user may have specified, multiple extra_src_dirs entries existed
at once and were run; one with the recursion set to true and one with
whatever the user specified. If the user disabled recursion of the
"test" extra_src_dir, then the injected value still ran it once...
4. The handling of extra files in the compiler module is fixed to
actually use the rebar_dir interface properly, and reinjects
non-default directory recursion settings into the swapped options
for the shimmed extra apps. Not doing this annotation step resulted
in the write for swapped opts to actually drop the configured
recursion value and make everything recursive all the time.
A single new test actually validates all of that behaviour and seems to
work fine.
This commit changes the location where rebar3 will extract
its libs upon calling a `local` command from `~/.cache/rebar3/lib`
to `~/.cache/rebar3/vsns/VERSION/lib`, with `VERSION` being
rebar3 current version.
It also updates the bin script to reflect these changes.
