Instead of relying only on modification times, this does a more complex
compatibility check if the modification times of the pubspec, lockfile,
and .packages file aren't ordered properly. If they are up-to-date, it
updates the modification times accordingly.

This also fixes a case where "pub run" wasn't properly checking that the
dependencies were up-to-date.

If the root directory of a package is .gitignored, it will no longer be
considered to be a "git package", since that just means that it'll be
seen to contain no files at all.

Pub won't upload gitignored files, so its validation shouldn't consider

Since there's no way to load resources without using the packages/
directory, this flag will introduce a lot of confusing unfixable
breakage. We should un-hide it once there's sufficient SDK support for
locating/loading resources (dart-lang/sdk#23990).

Previously, if a dependency depended on the entrypoint package, the
entrypoint would have all its direct dependencies re-printed. This fixes
that.

Previously, several commands automatically ran "pub get" implicitly before doing
their work. We've determined that this behavior is confusing, and for "pub run"
in particular, makes the executables seem much slower than they actually are.

This also allows us to make access to the entrypoint's package graph
synchronous.

The spec doesn't actually need all the data loaded from the package
graph; all it needs are the locations of packages which can be looked up
using their IDs and a SourceRegistry.

This also has it store its SourceRegistry, so that various methods don't
need to re-supply it.

It never really made sense for this to be asynchronous; most sources
didn't even do any IO to determine the directory. The only exception was
the git source, which would actually *clone a repository* if one didn't
exist yet. This heavyweight behavior wasn't a good fit for what looks
like a lightweight method anyway.

Making this synchronous has a ripple effect of making a bunch of other
methods synchronous, too. Hooray for synchrony!

* The package spec's reference to the entrypoint package was pointing to
  the hosted cache rather than the package's directory. This was caused
  by the package graph's instance of the entrypoint package incorrectly
  pointing to the cache; the graph now re-uses `entrypoint.root`.

* The package spec didn't contain relative paths for relative path
  dependencies. This was being missed by our tests because the package
  spec parser was automatically converting all paths to absolute at
  parse-time.
