On legacy Gemfiles with multiple remote sources, where all of them
support the compact index API, we were still falling back to full
indexes.
Fixing this also allows to simplifying the code.

Previously, when sorting and comparing git Gemfile vs lockfile sources during
`bundler/setup` to figure out whether we need to re-resolve or not, we
would try to find the default branch if nothing more specific was
specified in the Gemfile.
If the git cache has been deleted thought, that would fail.
The error would still be swallowed (and the branch would simply not be
displayed), but trying to clone would still generate the side effect of
creating the parent folder for the clone.
That could affect non-writable systems that don't expect `bundler/setup`
to write to the filesystem at all.
To fix this, override `Bundler::Source::Git#identifier` to use
exclusively static information, so it does not even try to clone the
repo nor generate any side effects.

When dependencies in path sources have changed, we'll be re-resolving,
and we can't really know whether the resolution will be valid or invalid
for the Ruby platform, so skip the removal in that case.

This error message is also printed when using `bundler/setup` in frozen
model, so we're not necessarily installing any gems when it happens.
This new message play nicer with all situations.

The `deployment` setting sets `path` to `vendor/bundle` implicitly, but
that should only apply if `path` is not set explicitly, at any level.

If Gemfile has a lot of dependencies, we have an optimization that uses
the full index in that case, assuming it's going to be faster.
I think this is an old optimization that predates compact index API
times, I believe we no longer need it these days.
Also, since a few releases ago we check for circular dependencies when
resolving by looping through all versions of each name and removing
those that have circular dependencies that would trip up the resolver.
This loop becomes actually very slow when full indexes are used because
to find dependencies of a gemspec, we need to explicitly fetch the
marshaled gemspec (`gemspec.rz` endpoint) for it, so the optimization
has the opposite effect of making things very slow.

When dependencies have changed, we'll be re-resolving, and we can't
really know whether the resolution will be valid or invalid for the Ruby
platform, so skip the removal in that case.
The fix worked, but made some other specs fail, and surfaced that the
`@dependencies_changed` attribute was actually being incorrect set when
explicitly unlocking. Fixed that with an early return.

I've never seen this error in real life, and if it was happening, I
think it's either some server side issue that would need to be fixed or
some transient issue. We should move away from the full index, since
it's slow, so let's stop recommending it.
* Replaces the wording of "is forbidden" with "cannot be used"
* Fixes the method signature of VersionRange::Empty#eql?

Given an existing application using native gems (e.g., nokogiri)
And a lockfile generated with a stable ruby version
When we test the application against ruby-head and `bundle install`
Then bundler should fall back to the generic ruby platform gem
Note that this test has been passing since 45931ac9
