SBProcess::ReadMemory and other related functions such as
WriteMemory are returning Python string() objects. This means
that in Python 3 that are returning Unicode objects. In reality
they should be returning bytes objects which is the same as a string
in Python 2, but different in Python 3. This patch updates the
generated SWIG code to return Python bytes objects for all
memory related functions.
One quirk of this patch is that the C++ signature of ReadCStringFromMemory
has it writing c-string data into a void*. This confuses our swig
typemaps which expect that a void* means byte data. So I hacked up
a custom typemap which maps this specific function to treat the
void* as string data instead of byte data.

The Windows 10 loader spawns threads at startup, so
tests which count threads or assume that a given user
thread will be at a specific index are incorrect in
this case. The fix here is to use the standard mechanisms
for getting the stopped thread (which is all we are
really interested in anyway) and correlating them with
the breakpoints that were set, and doing checks against
those things.
This fixes about 6 tests on Windows 10.

Starting with Windows 10, the Windows loader is itself multi-threaded,
meaning that the loader spins up a few threads to do process
initialization before it executes main. Windows delivers these
notifications asynchronously and they can come out of order, so
we can't be sure that the first thread we get a notification about
is actually the zero'th thread.
This patch fixes this by requesting the thread stopped at the
breakpoint that was specified, rather than getting thread 0 and
verifying that it is stopped at a breakpoint.

The logic for skipping over the stop-and-restart events was incorrect as it was also skipping the
expectations. Implement it properly. No test is affected by this as they were not encountering
these events, but I encountered this issue when trying to use this function in a new test.

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.

This module was originally intended to be imported by top-level
scripts to be able to find the LLDB packages and third party
libraries. Packages themselves shouldn't need to import it,
because by the time it gets into the package, the top-level
script should have already done this. Indeed, it was just
adding the same values to sys.path multiple times, so this
patch is essentially no functional change.
To make sure it doesn't get re-introduced, we also delete the
`use_lldb_suite` module from `lldbsuite/test`, although the
original copy still remains in `lldb/test`

This is the conclusion of an effort to get LLDB's Python code
structured into a bona-fide Python package. This has a number
of benefits, but most notably the ability to more easily share
Python code between different but related pieces of LLDB's Python
infrastructure (for example, `scripts` can now share code with
`test`).
