Pavel Labath 22e71a030e Add a "watchpoint" test category and annotate tests appropriately
Most of the watchpoint tests are organized into subtrees, so we can use the
file-based .categories approach to annotate them. The exception are the
concurrent_events tests, which needed to be annotated on a per-test basis.

The motivation behind this is to provide an easy way to disable watchpoint
tests on systems where the watchpoint functionality is not present/unreliable.

Pavel Labath f753bfeeec Fix LLVM_LINK_LLVM_DYLIB build (pr35053)
Summary:
r316368 broke this build when it introduced a reference to a pthread
function to the Utility module. This caused cmake to generate an
incorrect link line (wrong order of libs) because it did not see the
dependency from Utility to the system libraries. Instead these libraries
were being manually added to each final target.

This changes moves the dependency management from the individual targets
to the lldbUtility module, which is consistent with how llvm does it.
The final targets will pick up these libraries as they will be a part of
the link interface of the module.

Technically, some of these dependencies could go into the host module,
as that's where most of the os-specific code is, but I did not try to
investigate which ones.

Summary:

enable more sharing of code (mainly the loop detection stuff).

Pavel Labath 7263f1bda6 Invert ArchSpec<->Platform dependency
Summary:
ArchSpec::SetTriple was taking a Platform as an argument, and used it to
fill in missing pieces of the specified triple. I invert the dependency
by moving this code to other classes. For this purpose, I've created
three new functions.
- HostInfo::GetAugmentedArchSpec: fills in the triple using the host
  platform (this used to be implemented by passing a null platform
  pointer). By putting this code in the Host module, we can provide a
  way to anyone who does not have a platform instance (lldb-server) an
  easy way to get Host data.
- Platform::GetAugmentedArchSpec: if you have a platform instance, you
  can call this to let it fill in the triple.
- static Platform::GetAugmentedArchSpec: implements the "if platform ==
  0 then use_host() else use_platform()" part.

Versions of android before kitkat implemented pselect non-atomically,

This patch implements a direct call to the the pselect kernel syscall,

Pavel Labath 7e17fc5e09 Default to using in-tree clang for building test executables
Summary:
Using the in-tree clang should be the default test configuration as that
is the one compiler that we can be sure everyone has (better
reproducibility of test results). Also, it should hopefully reduce the
impact of pr35040.

This also reduces the number of settings which control the compiler
used. LLDB_TEST_C_COMPILER is used for C files and
LLDB_TEST_CXX_COMPILER for C++ files. Both of the settings default to
the in-tree clang.

Pavel Labath e3f6eb1a74 Revert "[lldbtests] Handle errors instead of crashing."
The commit breaks the case where you specify just a filename to the
compiler. Previously, it would look up the compiler in your path, now it
complains that the compiler is not found. One of the lldb buildbots is
depending on this. It seems like a nice feature to have, as it means
less typing and being able to avoid hard-coding the system compiler path
in the bot config.

This reverts commit r316393.

Pavel Labath f877a0820c Use ipv4 localhost address in lldb-server tests
Since the ipv6 patch, we've experienced occasional flakyness in
lldb-server tests. This was due to the fact that lldb-server was trying
to listen on both v4 and v6 localhost sockets (and consider it a success
if at least one of them succeeded), while the test framework was only
trying to connect to the v4 one.

This change makes sure lldb-server only listens on the v4 socket.

Pavel Labath d813309e03 Logging: Disable logging after fork()
Summary:
We had a bug where if we had forked (in the ProcessLauncherPosixFork)
while another thread was writing a log message, we would deadlock. This
happened because the fork child inherited the locked log rwmutex, which
would never get unlocked. This meant the child got stuck trying to
disable all log channels.

The bug existed for a while but only started being apparent after
D37930, which started using ThreadLauncher (which uses logging) instead
of std::thread (which does not) for launching TaskPool threads.

The fix is to use pthread_atfork to disable logging in the forked child.

The pthread_atfork trick breaks on android, because
pthread_rwlock_unlock detects that it is not the same thread which

deadlock (only this time it happens deterministically instead of at
random). Reverting to find a better solution.

Pavel Labath c596e9088f lldb-server tests: Add support for testing debugserver
Summary:
This adds support for running the lldb-server test suite (currently consisting
of only one test) against the debugserver. Currently, the choice which binary
to test is based on the host system. This will need to be replaced by something
more elaborate if/when lldb-server starts supporting debugging on darwin.

I need to make a couple of tweaks to the test client to work with debugserver:
- debugserver has different command-line arguments - launching code adjusted to
  handle that
- debugserver sends duplicate "medata" fields in the stop reply packet -
  adjusted stop-reply parsing code to handle that
- debugserver replies to the k packet instead of just dropping the connection -
  stopping code adjusted, although we should probably consider aligning the
  behavior of the two stubs in this case

unique_ptr, and methods that used to hand out thread shared pointers now
