Change r278527 was filtering out too many libraries.
The Xcode lldb-gtest target depends on linking libgtest*.a,
but those were not being included. This caused the lldb-gtest
linkage step to fail to find a main entry point that is present
in the filtered out libs.
This change restores the libgtest* libraries to the link list
by whitelisting them in the filter.

The Xcode macOS build of LLDB is currently broken after
https://reviews.llvm.org/D23232 landed, see
http://lab.llvm.org:8080/green/job/lldb_build_test/20014/console,
because we’re trying to link against all .a files found in the
llvm-build/lib directory. Let’s be more specific in what we link
against. This patch applies a regexp to only use “libclang.*”,
“libLLVM.*” and not “libclang_rt.*” static archives.

This change opens a socket pair and passes the second socket pair file descriptor down to the debugserver binary using a new option: "--fd=N" where N is the file descriptor. This file descriptor gets passed via posix_spawn() so that there is no need to do any bind/listen or bind/accept calls and eliminates the hanshake unix socket that is used to pass the result of the actual port that ends up being used so it can save time on launch as well as being faster.
This is currently only enabled on __APPLE__ builds. Other OSs should try modifying the #define from ProcessGDBRemote.cpp but the first person will need to port the --fd option over to lldb-server. Any OSs that enable USE_SOCKETPAIR_FOR_LOCAL_CONNECTION in their native builds can use the socket pair stuff. The #define is Apple only right now, but looks like:
#if defined (__APPLE__)
#define USE_SOCKETPAIR_FOR_LOCAL_CONNECTION 1
#endif

debuggerd is a crash reporting system on android what installs some
signal handler for SEGV to print a backtrace in the log. Its behavior
breaks tests where the test tries to continue after a SEGV so we skip
them as this behavior isn't required on android anyway.

FD_SETSIZE on windows limits the number of file descriptors, rather than their individual
magnitude (the underlying implementation uses an array rather than a bitset). This meant that the
assert in the SelectHelper was incorrect, and failing all the time. Fix that.
I am not sure whether this should be #ifdef MSVC, or #ifdef WINDOWS, but my feeling is that a
more posix-conforming implementation on windows would choose the bitset implementation, so I'm
sticking with the former.

Options used to store a reference to the CommandInterpreter instance
in the base Options class. This made it impossible to parse options
independent of a CommandInterpreter.
This change removes the reference from the base class. Instead, it
modifies the options-parsing-related methods to take an
ExecutionContext pointer, which the options may inspect if they need
to do so.

Factor out some common logic used to find the runtime library in a list
of modules.

Adapters for instrumentation runtimes have to do two basic things:
1) Load a runtime library.
2) Install breakpoints in that library.
This logic is duplicated in the adapters for asan and tsan. Factor it
out and document bits of it to make it easier to add new adapters.
I tested this with check-lldb, and double-checked
testcases/functionalities/{a,t}san.

gettimeofday() isn't defined without a special header. Rather
than rely on C apis, let's just use modern C++11 to do this
portably on all platforms using std::chrono.

It's always hard to remember when to include this file, and
when you do include it it's hard to remember what preprocessor
check it needs to be behind, and then you further have to remember
whether it's windows.h or win32.h which you need to include.
This patch changes the name to PosixApi.h, which is more appropriately
named, and makes it independent of any preprocessor setting.
There's still the issue of people not knowing when to include this,
because there's not a well-defined set of things it exposes other
than "whatever is missing on Windows", but at least this should
make it less painful to fix when problems arise.
This patch depends on LLVM revision r278170.

Resumbitting the commit after fixing the following problems:
- broken unit tests on windows: incorrect gtest usage on my part (TEST vs. TEST_F)
- the new code did not correctly handle the case where we went to interrupt the process, but it
stopped due to a different reason - the interrupt request would remain queued and would
interfere with the following "continue". I also added a unit test for this case.
This reapplies r277156 and r277139.

also take the opportunity to replace NULL with nullptr and add clang-format guards to prevent it
from messing up the nice table there.

This removes references to PT_XXX macros from the file, as they were not used anyway. It also
changes the macro used to check for the definition of __ptrace_request, as there are other C
libraries which do not define this type.

It only contained a reimplementation of std::to_string, which I have replaced with usages of
pre-existing llvm::to_string (also, injecting members into the std namespace is evil).
