Summary:
This patch adds a framework for adding descriptions to the command completions we provide.
It also adds descriptions for completed top-level commands so that we can test this code.
Completions are in general supposed to be displayed alongside the completion itself. The descriptions
can be used to provide additional information about the completion to the user. Examples for descriptions
are function signatures when completing function calls in the expression command or the binary name
when providing completion for a symbol.
There is still some boilerplate code from the old completion API left in LLDB (mostly because the respective
APIs are reused for non-completion related purposes, so the CompletionRequest doesn't make sense to be
used), so that's why I still had to change some function signatures. Also, as the old API only passes around a
list of matches, and the descriptions are for these functions just another list, I had to add some code that
essentially just ensures that both lists are always the same side (e.g. all the manual calls to
`descriptions->AddString(X)` below a `matches->AddString(Y)` call).
The initial command descriptions that come with this patch are just reusing the existing
short help that is already added in LLDB.
An example completion with descriptions looks like this:
```
(lldb) pl
Available completions:
platform -- Commands to manage and create platforms.
plugin -- Commands for managing LLDB plugins.
```

Summary:
This patch adds initial code completion support for the `expr` command.
We now have a completion handler in the expression CommandObject that
essentially just attempts to parse the given user expression with Clang with
an attached code completion consumer. We filter and prepare the
code completions provided by Clang and send them back to the completion
API.
The current completion is limited to variables that are in the current scope.
This includes local variables and all types used by local variables. We however
don't do any completion of symbols that are not used in the local scope (or
in some other way already in the ASTContext).
This is partly because there is not yet any code that manually searches for additiona
information in the debug information. Another cause is that for some reason the existing
code for loading these additional symbols when requested by Clang doesn't seem to work.
This will be fixed in a future patch.

As Jim pointed out, we don't need to manually create a target
here because we already create a target implicitly in the very
next line (which means we just created a target and don't use it).
This patch just removes the line that creates the first unused target.

Summary:
The test suite has often unnecessary trailing whitespace, and sometimes
unnecessary trailing lines or a missing final new line. This patch just strips
trailing whitespace/lines and adds missing newlines at the end.

The test I added in r327110 is failing on windows because of "import
pexpect". However, this import is no longer necessary as these tests
don't use pexpect anymore.
In fact, it seems that all TestCompletion tests are passing on windows
after this, so I enable all of them.

Summary:
The args class is used in plenty of places (a lot of them in the lower lldb
layers) for representing a list of arguments, and most of these places don't
care about option parsing. Moving the option parsing out of the class removes
the largest external dependency (there are a couple more, but these are in
static functions), and brings us closer to being able to move it to the
Utility module).
The new home for these functions is the Options class, which was already used
as an argument to the parse calls, so this just inverts the dependency between
the two.
The functions are themselves are mainly just copied -- the biggest functional
change I've made to them is to avoid modifying the input Args argument (getopt
likes to permute the argument vector), as it was weird to have another class
reorder the entries in Args class. So now the functions don't modify the input
arguments, and (for those where it makes sense) return a new Args vector
instead. I've also made the addition of a "fake arg0" (required for getopt
compatibility) an implementation detail rather than a part of interface.
While doing that I noticed that ParseForCompletion function was recording the
option indexes in the shuffled vector, but then the consumer was looking up the
entries in the unshuffled one. This manifested itself as us not being able to
complete "watchpoint set variable foo --" (because getopt would move "foo" to
the end). Surprisingly all other completions (e.g. "watchpoint set variable foo
--w") were not affected by this. However, I couldn't find a comprehensive test
for command argument completion, so I consolidated the existing tests and added
a bunch of new ones.

I added a "thread-stop-format" to distinguish between the form
that is just the thread info (since the stop printing immediately prints
the frame info) and one with more frame 0 info - which is useful for
"thread list" and the like.
I also added a frame.no-debug boolean to the format entities so you can
print frame information differently between frames with source info and those
without.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

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`

For convenience, we had added the folder that dotest.py was in
to sys.path, so that we could easily write things like
`import lldbutil` from anywhere and any test. This introduces
a subtle problem when using Python's package system, because when
unittest2 imports a particular test suite, the test suite is detached
from the package. Thus, writing "import lldbutil" from dotest imports
it as part of the package, and writing the same line from a test
does a fresh import since the importing module was not part of
the same package.
The real way to fix this is to use absolute imports everywhere. Instead
of writing "import lldbutil", we need to write "import
lldbsuite.test.util". This patch fixes up that and all other similar
cases, and additionally removes the script directory from sys.path
to ensure that this can't happen again.

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`).
