This folds the distinction between "resolved" and "unresolved"
descriptions into the distinction between PackageIds and PackageRefs. In
other words, all PackageIds now have resolved descriptions and all
PackageRefs now have unresolved descriptions. This makes it easier to
track which descriptions are resolved and express resolution constraints
via the type system.

This also restricts the creation of PackageRefs and PackageIds to source
classes, which helps ensure that the description format—which is an
implementation detail—doesn't leak into surrounding code.

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!

If you pass "--offline" to either, it will treat your system cache
as if it were the package server. Running update in offline also
prints a warning that you may have selected an older version of a
package.

This also changes the SDK layout by replacing the "pkg" directory, which
contained the full source of all the packages needed by pub and dartdoc, with a
"packages" directory that contains only their lib directories. This directory is
used as the package root for pub and dartdoc when run from the SDK.

fileExists and dirExists will now both return true for symlinks only if those
symlinks are unbroken and point to entries of the appropriate type. entryExists
will return true for any symlink as well, broken or unbroken.

deleteDir and deleteFile have been replaced with a single function, deleteEntry.
This will delete whatever filesystem entry exists at the path specified, whether
it's a file, directory, or symlink (broken or unbroken).

After running pub install or update, it will look at all of the
selected packages and see if their SDK constraints match the
current SDK. If not, it will show a (hopefully) helpful error
message.

Future.then() will now implicitly wrap the callback result in a
future if it isn't one, so this manual wrapping can be removed.

Also take advantage of the fact that Future.immediate() is always
async now and remove some workarounds.

Finally, noticed there were two copies of the git-related code
floating around so killed the old one.

This is prep work for SDK constraints. It moves the SDK
version-related code out of SdkSource (which will go away at some
point) into its own library.

I also removed the need for the DART_SDK env variable. It will
still be used if set (which the tests need), but if not set, Pub
will locate the SDK.
Clean up a few static warnings.

We'll have to tune which things we log over time, but this covers
most IO operations which is where almost all of our problems come
from.

This patch also means that going forward you should no longer call
print() or printError() (which is gone) directly. Instead:

print() -> log.message()
printError() -> log.error()

That ensures all messages will correctly get added to the log's
transcript.
