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`).

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.

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.

"test/api/multithreaded/TestMultithreaded.py" works without errors.
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.

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.

Six provides six.u() which resolves to either u"" or "" depending on
Python version, and and six.unichr() which resolves to either unichr()
or chr() depending on Python version. Use these functions anywhere
where we were relying on u"" or unichr().

Apparently there were tons of instances I missed last time, I
guess I accidentally ran 2to3 non-recursively. This should be
every occurrence of a print statement fixed to use a print function
as well as from __future__ import print_function being added to
every file.
After this patch print statements will stop working everywhere in
the test suite, and the print function should be used instead.

This is necessary in order to allow third party modules to be
located under lldb/third_party rather than under the test
folder directly.
Since we're already touching every test file anyway, we also
go ahead and delete the unittest2 import and main block wherever
possible. The ability to run a test as a standalone file has
already been broken for some time, and if we decide we want this
back, we should use unittest instead of unittest2.
A few places could not have the import of unittest2 removed,because
they depend on the unittest2.expectedFailure or skip decorators.
Removing all those was orthogonal in spirit to the purpose of this
CL, so the import of unittest2 remains in those files that were
using it for its test decorators. Those can be addressed
separately.

Summary:
Along with this, support for an optional argument to the "num_children"
method of a Python synthetic child provider has also been added. These have
been added with the following use case in mind:
Synthetic child providers currently have a method "has_children" and
"num_children". While the former is good enough to know if there are
children, it does not give any insight into how many children there are.
Though the latter serves this purpose, calculating the number for children
of a data structure could be an O(N) operation if the data structure has N
children. The new method added in this change provide a middle ground.
One can call GetNumChildren(K) to know if a child exists at an index K
which can be as large as the callers tolerance can be. If the caller wants
to know about children beyond K, it can make an other call with 2K. If the
synthetic child provider maintains state about it counting till K
previosly, then the next call is only an O(K) operation. Infact, all
calls made progressively with steps of K will be O(K) operations.

Summary:
Loop detection code is being called before every element access. Although it tries to cache some
of the data by remembering the loop-free initial segment, every time it needs to increase this
segment, it will start from scratch. For the typical usage pattern, where one accesses the
elements in order, the loop detection will need to be run after every access, resulting in
quadratic behavior. This behavior is noticable even for the default 255 element limit.
In this commit, I rewrite the algorithm to be truly incremental -- it maintains the state of its
loop-detection runners between calls, and reuses them when it needs to check another segment.
This way, each part of the list is scanned only once, resulting in linear behavior.
Also note that I have changed the operator== of ListEntry to do the comparison based on the
value() function (instead of relying on ValueObjectSP equality). In my experiments, I kept
getting different ValueObjectSPs when going through the same element twice.

unknowns
* ArchSpec::MergeFrom() would erroneously promote an unspecified
unknown to a specified unknown when both the ArchSpec and the merged
in ArchSpec were both unspecified unknowns. This no longer happens,
which fixes issues with global module cache lookup in some
situations.
* Added ArchSpec::DumpTriple(Stream&) that now properly prints
unspecified unknowns as '*' and specified unknows as 'unknown'.
This makes it trivial to tell the difference between the two.
Converted printing code over ot using DumpTriple() rather than
building from scratch.
* Fixed up a couple places that were not guaranteeing that an
unspecified unknown was recorded as such.

Introduce the notion of Language-based formatter prefix/suffix
This is meant for languages that share certain data types but present them in syntatically different ways, such that LLDB can now have language-based awareness of which of the syntax variations it has to present to the user when formatting those values
This is goodness for new languages and interoperability, but is NFC for existing languages. As such, existing tests cover this

This test was timing out because the test inferior was forking a child, which was not terminated
correctly. The test contained provisions to terminate this child, but these were no longer
working. The idea was to wake up upon receiving SIGTERM and then kill the child. However, this
was failing because the test first tried to use SIGHUP, which ended up killing the inferior.
Fix: make sure we catch SIGHUP also.

Currently most of the test files have a separate dwarf and a separate
dsym test with almost identical content (only the build step is
different). With adding dwo symbol file handling to the test suit it
would increase this to a 3-way duplication. The purpose of this change
is to eliminate this redundancy with generating 2 test case (one dwarf
and one dsym) for each test function specified (dwo handling will be
added at a later commit).
Main design goals:
* There should be no boilerplate code in each test file to support the
multiple debug info in most of the tests (custom scenarios are
acceptable in special cases) so adding a new test case is easier and
we can't miss one of the debug info type.
* In case of a test failure, the debug symbols used during the test run
have to be cleanly visible from the output of dotest.py to make
debugging easier both from build bot logs and from local test runs
* Each test case should have a unique, fully qualified name so we can
run exactly 1 test with "-f <test-case>.<test-function>" syntax
* Test output should be grouped based on test files the same way as it
happens now (displaying dwarf/dsym results separately isn't
preferable)
Proposed solution (main logic in lldbtest.py, rest of them are test
cases fixed up for the new style):
* Have only 1 test fuction in the test files what will run for all
debug info separately and this test function should call just
"self.build(...)" to build an inferior with the right debug info
* When a class is created by python (the class object, not the class
instance), we will generate a new test method for each debug info
format in the test class with the name "<test-function>_<debug-info>"
and remove the original test method. This way unittest2 see multiple
test methods (1 for each debug info, pretty much as of now) and will
handle the test selection and the failure reporting correctly (the
debug info will be visible from the end of the test name)
* Add new annotation @no_debug_info_test to disable the generation of
multiple tests for each debug info format when the test don't have an
inferior

Summary:
The following situation occured in TestAttachResume:
The inferior was stoped at a breakpoint and we did a continue, immediately followed by a detach.
Since there was a trap instruction under the IP, the continue did a step-over-breakpoint before
resuming the inferior for real. In some cases, the detach command was executed between these two
events (after the step-over stop, but before continue). Here, public state was running, but
private state was stopped. This caused a problem because HaltForDestroyOrDetach was checking the
public state to see whether it needs to stop the process (call Halt()), but Halt() was checking
the private state and concluded that there is nothing for it to do.
Solution: Instead of Halt() call SendAsyncInterrupt(), which will then cause Halt() to be
executed in the context of the private state thread. I also rename HaltForDestroyOrDetach to
reflect it does not call halt directly.
