Summary:
Virtual dynamic shared objects, or vdso files were
not loaded for Linux OS.In Bug 17384 the call
stack could not be unwinded from functions
residing in the vdso object.
This commit adds support for loading such files by
reading the Aux vectors since a vdso is invisibily
mapped to the inferiors address space and the
actual file is not present in the filesystem. The
presence of the vdso is detected by inspecting
the Aux vector for AT_SYSINFO_EHDR tag.

The idea behind this patch is to expose the meat of
LLDB's Python infrastructure (test suite, scripts, etc)
as a single package. This makes reusability and code
sharing among sub-packages easy.

This code was modifying the cursor and then expecting the editline
API call to see the effect for the next operation. This is misusing
the API. Newer editlines break on this code, fixed by this.

* Remove an unneccessary re-computaion on arch spec from the ELF file
* Use a local cache to optimize name based section lookups in symtab
parsing
* Optimize C++ method basename validation with replacing a regex with
hand written code
These modifications reduce the time required to parse the symtab from
large applications by ~25% (tested with LLDB as inferior)

Summary:
This change deprecates -m/+m dotest options (the options are still recognized but they print an
error message pointing to the new options) and adds a new lldb-mi test category instead. To just
run lldb-mi tests, use '-G lldb-mi'. To skip lldb-mi tests, use '--skip-category lldb-mi'. All
lldb-mi tests are marked as such using the getCategories method on the base MiTestCaseBase class
and the @lldbmi_test decorator is not needed. In case one still needs to annotate a specific test
function as an lldb-mi test, one can use the @add_test_categories(['lldb-mi']) decorator to
achieve that.

Summary:
Gdb-remote's async thread sent out the eBroadcastBitRunPacketSent message *before* actually
sending out the continue packet. Since it's this message the actually triggers the public state
transition, it could happen (and it did happen in TestAttachResume, which does an "process
interrupt" right after a continue) that we attempt to stop the inferior before it was actually
started (which obviously did not end well). This fixes the problem by moving the broadcast after
the packet was actually sent.

On some combination of platform and c++ library, this dependency was causing the test to fail for reasons tangential to its real objective

Summary:
This does not have any functionnal difference but I found myself
searching for 'struct RegisterInfo$' to find a definition and couldn't
find it. The version without typedef seems more common so let's try and
be consistent.

On UNIX (but not Darwin) the username needs to be respected when creating a
temporary module directory, so that different users don't pollute each others'
module caches.

Python 3 has a different syntax for octal literals than Python 2
and they are incompatible with each other. Six doesn't provide
a transparent wrapper around this, so the most sane thing to do
is to not use octal literals. If you need an octal literal,
use a decimal literal and if it's not obvious what the value is,
provide the value in octal as a comment.

The problem was that the @skipIfNoSBHeaders on darwin was trying to use self.lib_dir when it hadn't been set yet.
I looked at the code and places were required to set "self.lib_dir" for no real reason as all places that used it just used the LLDB_LIB_DIR environment variable. So I removed all uses of self.lib_dir and replaced them to use 'os.environ["LLDB_LIB_DIR"]'. Did the same for self.implib_dir.

Also since we always read in the DWARF data or mmap it, we don't need to make a copy of the strings for the directories and file names, we can just store "cosnt char *" values. Every place that uses the prologues use them temporarily and then throw them away so no one is expecting the directory and filename strings to live longer than the parse functions.

Python3 has no analogue to sys.maxint since ints in Python 3 have
arbitrary size. However, the distinction was not actually important
in any of these cases, and in a few cases using maxint was already
a bug to begin with.

This avoids the need to query the PC for private resume operations (public resumes have the PC
from the bigger jStopInfo packet) and speeds up the stepping on an android target by about 10%
(it some cases even more).

Adds option -c <x,y,z> to the 'language renderscript kernel breakpoint set' command.
Breaks only on the invocation of the kernel with specified coordinate.
Implemented by adding a callback to the kernel breakpoint which checks the coordinates of every invocation.

Summary:
Per discussions on the mailing list, I have implemented a decorator which annotates individual
test methods with categories. I have used this framework to replace the '-a' and '+a'
command-line switches (now '-G pyapi' and '--skip-category pyapi') and the @python_api_test
decorator (now @add_test_categories('pyapi')). The test suite now gives an error message
suggesting the new options if the user specifies the deprecated +/-a switches. If the general
direction is good, I will follow this up with other switches.

This is just a trivial patch that corrects a couple of return value account to function's return type.
Also corrects typo in hardware breakpoint handler.

Also added a placeholder Editline gtest for some code that I'll add as soon
as I make sure this addition doesn't break any of the build bots.
This change also introduces some Xcode user-defined variables that I've used
to attempt to isolate the way Python is integrated into the build. I don't have
the rest of LLDB using it yet, I'm using the gtests as my guinea pig on that.
Currently these are:
PYTHON_FRAMEWORK_PATH
PYTHON_VERSION_MAJOR
PYTHON_VERSION_MINOR
I will convert the rest over to it after this gets a little time to bake
and any kinks are worked out of it.

I am also letting a debugserver-related project entry slide in
