This reapplies r20952, r20953, r20954 together with hiding sleep from
dart:io in a number of tests.

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).

Now that pub is using scheduled_test, it should at least be clearer what's going
on if these tests start flaking again.

We're removing these workarounds in the hopes that the pub tests won't resume
flaking. If they do, this CL should be rolled back.

These tests were marked as test() rather than integration() and so their
schedules weren't getting run at all.

This changes the exception behavior of getRange. It used to accept
a length of zero, no matter what start value. Now the start value
must be a valid list index.
