Prior to MSVC 2015 we had to manually include this header any
time we were going to include <thread> or <future> due to a
bug in MSVC's STL implementation. This has been fixed in MSVC
for some time now, and we require VS 2015 minimum, so we can
remove this across all subprojects.

Currently, in the default configuration, the "install" target will
install all llvm executables unversioned, except for three lldb tools
which will be installed versioned (with a non-versioned symlink). This
rectifies that situation.

Summary:
This patch adds accurate dependency specifications to the mail LLDB libraries and tools.
In all cases except lldb-server, these dependencies are added in addition to existing dependencies (making this low risk), and I performed some code cleanup along the way.
For lldb-server I've cleaned up the LLVM dependencies down to just the minimum actually required. This is more than lldb-server actually directly references, and I've left a todo in the code to clean that up.

In LLVM's CMake we have a convention that components have both a build and an install target. Making LLDB follow this convention will allow LLDB to take advantage of the LLVM_DISTRIBUTION_COMPONENTS build option from LLVM.

Summary: I was building lldb using cross mingw-w64 toolchain on Linux and observed some issues. This is first patch in the series to fix that build. It mostly corrects the case of include files and adjusts some #ifdefs from _MSC_VER to _WIN32 and vice versa. I built lldb on windows with VS after applying this patch to make sure it does not break the build there.

Summary:
This replaces all the uses of the __ANDROID_NDK__ define with __ANDROID__. This
is a preparatory step to remove our custom android toolchain file and rely on
the standard android NDK one instead, which does not provide this define.
Instead I rely, on __ANDROID__, which is set by the compiler.
I haven't yet removed the cmake variable with the same name, as we will need to
do something completely different there -- NDK toolchain defines
CMAKE_SYSTEM_NAME to Android, while our current one pretends it's linux.

Summary:
The dependencies of our libraries (only liblldb, really) we marked as public, which caused all
their dependencies to be repeated when linking any executables to them. This is a problem because
then all the .a files could end up being linked twice, once to liblldb and once
again to to the executable linking against liblldb (lldb, lldb-mi). As it turns out,
our build actually depends on this behavior:
- on windows, lldb does not have getopt, so it pulls it from inside liblldb, even
though getopt is not a part of the exported interface of liblldb (maybe some of
the bsd variants have this problem as well)
- lldb-mi uses llvm, which again is not exported by liblldb
This change does not actually fix these problems (that is going to be a hard
one), but it does make them explicit by moving this magic from add_lldb_library
to the places the executable targets are defined. That way, I can link the
additional .a files only on targets that really need it, and the other targets
can build cleanly and make sure we don't regress further. It also fixes the
LLVM_LINK_LLVM_DYLIB build on linux.

*** 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.

Disabling buffering exposes a bug in the MS VS 2015 CRT implementation of fgets, where you sometimes have to hit Enter twice, depending on if the input had an odd or even number of characters.
This was hidden until a few days ago by the Python initialization which was re-enabling buffering on the streams. A few days ago, Enrico make the Python initialization on-demand, which exposed this problem.

The Windows SDK provides a version of signal() that is much more
limited compared to other platforms. It only supports about 5-6
signal values. LLDB uses signals for a number of things, most
notably to handle Ctrl+C so we can gracefully shut down. The
portability solution to this on Windows has been to provide a
hand-rolled implementation of `signal` using the name `signal`
so that you could write code that simply calls signal directly
and it would work.
But this introduces a multiply defined symbol with the builtin
version and depending on how you included header files, you could
get yourself into a situation where you had linker errors. To
make matters worse, it led to a ton of compiler warnings. Worst
of all though is that this custom implementation of signal was,
in fact, identical for the purposes of handling Ctrl+C as the
builtin implementation of signal. So it seems to have literally
not been serving any useful purpose.
This patch deletes all the custom signal() functions for Windows,
and includes the signal.h system header, so that any calls to
signal now go to the actual version provided by the Windows SDK.

working directory by default -- a typical security problem that we
need to be more conservative about.
It adds a new target setting, target.load-cwd-lldbinit which may
be true (always read $cwd/.lldbinit), false (never read $cwd/.lldbinit)
or warn (warn if there is a $cwd/.lldbinit and don't read it). The
default is set to warn. If this is met with unhappiness, we can look
at changing the default to true (to match current behavior) on a
different platform.
This does not affect reading of ~/.lldbinit - that will still be read,
as before. If you run lldb in your home directory, it will not warn
about the presence of a .lldbinit file there.
I had to add two SB API - SBHostOS::GetUserHomeDirectory and
SBFileSpec::AppendPathComponent - for the lldb driver code to be
able to get the home directory path in an OS neutral manner.
The warning text is
There is a .lldbinit file in the current directory which is not being read.
To silence this warning without sourcing in the local .lldbinit,
add the following to the lldbinit file in your home directory:
settings set target.load-cwd-lldbinit false
To allow lldb to source .lldbinit files in the current working directory,
set the value of this variable to true. Only do so if you understand and
accept the security risk.

An OBJECT library is a special type of CMake library that produces
no archive, has no link interface, and no link inputs. It is like
a regular archive, just without the physical output. To link
against an OBJECT library, you reference it in the *source* file
list of a library using the special syntax $<TARGET_OBJECTS:lldbAPI>.
This will cause every object file to be passed to the linker
independently, as opposed to a single archive being passed to the
linker.
This is *extremely* important on Windows. lldbAPI exports all of the
SB classes using __declspec(dllexport). Unfortunately for technical
reasons it is not possible (well, extremely difficult) to get the
linker to propagate a __declspec(dllexport) attribute from a symbol
in an object file in an archive to a DLL that links against that
archive. The solution to this is for the DLL to link the object files
directly. So lldbAPI must be an OBJECT library.
This fixes an issue that has been present since the duplicated
lldbAPI file lists were removed, which would cause linker failures.
As a side effect, this also makes LLDB_DISABLE_PYTHON=1 work again
on Windows, which was previously totally broken.

way you can run an lldb command targeted at a particular target, thread or process w/o having to

do that (RunCommandInterpreter, HandleCommands, HandleCommandsFromFile) to gather
the options into an options class. Also expose that to the SB API's.
Change the way the "-o" options to the lldb driver are processed so:
1) They are run synchronously - didn't really make any sense to run the asynchronously.
2) The stop on error
3) "quit" in one of the -o commands will not quit lldb - not the command interpreter
that was running the -o commands.
I added an entry to the run options to stop-on-crash, but I haven't implemented that yet.

We would previously simply assume that the write would always succeed. However,
write(2) may return -1 for error as well as fail to perform a complete write (in
which case the returned number of bytes will be less than the requested bytes).
Explicitly check if an error condition is encountered. This would previously
not be caught as we default initialized success to true. Add an assertion that
we always perform a complete write (a continuous retry could be added to ensure
that we finish writing completely).
This was caught by GCC's signed comparison warning and manual inspection.
