Python 3 - Turn on absolute imports, and fix existing imports.
Absolute imports were introduced in Python 2.5 as a feature
(e.g. from __future__ import absolute_import), and made default
in Python 3.
When absolute imports are enabled, the import system changes in
a couple of ways:
1) The `import foo` syntax will *only* search sys.path. If `foo`
isn't in sys.path, it won't be found. Period. Without absolute
imports, the import system will also search the same directory
that the importing file resides in, so that you can easily
import from the same folder.
2) From inside a package, you can use a dot syntax to refer to higher
levels of the current package. For example, if you are in the
package lldbsuite.test.utility, then ..foo refers to
lldbsuite.test.foo. You can use this notation with the
`from X import Y` syntax to write intra-package references. For
example, using the previous locationa s a starting point, writing
`from ..support import seven` would import lldbsuite.support.seven
Since this is now the default behavior in Python 3, this means that
importing from the same directory with `import foo` *no longer works*.
As a result, the only way to have portable code is to force absolute
imports for all versions of Python.
See PEP 0328 [https://www.python.org/dev/peps/pep-0328/] for more
information about absolute and relative imports.

dotest: improvements to the pexpect tests
Summary:
While working on r370054, i've found it frustrating that the test output
was compeletely unhelpful in case of failures. Therefore I've decided to
improve that. In this I reuse the PExpectTest class, which was one of
our mechanisms for running pexpect tests, but which has gotten orhpaned
in the mean time.
I've replaced the existing send methods with a "expect" method, which
I've tried to design so that it has a similar interface to the expect
method in regular non-pexpect dotest tests (as it essentially does
something very similar). I've kept the ability to dump the transcript of
the pexpect communication to stdout in the "trace" mode, as that is a
very handy way to figure out what the test is doing. I've also removed
the "expect_string" method used in the existing tests -- I've found this
to be unhelpful because it hides the message that would be normally
displayed by the EOF exception. Although vebose, this message includes
some important information, like what strings we were searching for,
what were the last bits of lldb output, etc. I've also beefed up the
class to automatically disable the debug info test duplication, and
auto-skip tests when the host platform does not support pexpect.
This patch ports TestMultilineCompletion and TestIOHandlerCompletion to
the new class. It also deletes TestFormats as it is not testing anything
(definitely not formats) -- it was committed with the test code
commented out (r228207), and then the testing code was deleted in
r356000.
