abd06b4c9b Make the presence of stdin and stdout optional.
The idea behind Nuxi CloudABI is that it is targeted at (but not limited to)
running networked services in a sandboxed environment. The model behind stdin,
stdout and stderr is strongly focused on interactive tools in a command shell.
CloudABI does not support the notion of stdin and stdout, as 'standard
input/output' does not apply to services. The concept of stderr does makes
sense though, as services do need some mechanism to log error messages in a
uniform way.

This patch extends libc++ in such a way that std::cin and std::cout and the
associated <cstdio>/<cwchar> functions can be disabled through the flags
_LIBCPP_HAS_NO_STDIN and _LIBCPP_HAS_NO_STDOUT, respectively. At the same time
it attempts to clean up src/iostream.cpp a bit. Instead of using a single array
of mbstate_t objects and hardcoding the array indices, it creates separate
objects that declared next to the iostream objects and their buffers. The code
is also restructured by interleaving the construction and setup of c* and wc*
objects. That way it is more obvious that this is done identically.

The c* and wc* objects already have separate unit tests. Make use of this fact
by adding XFAILs in case libcpp-has-no-std* is set. That way the tests work in
both directions. If stdin or stdout is disabled, these tests will therefore
test for the absence of c* and wc*.

43dbeea66f Remove the state_types array.
If we want to add support for making std::cin and std::cout optional, it
is impractical to have all of the mbstate_t objects in one array. This
would mean that if std::cin and std::cout are omitted, the state_types
array is only used partially.

Solve this by using separate global variables. These are placed right
next to the iostream object and the buffer, meaning we can easily #ifdef
them away.

3f86893b6c Don't let time_put test use implementation dependent constructs.
The time_put test doesn't seem to work on Linux and CloudABI. For Linux
we already have an XFAIL. Closer inspection seems to reveal that this
test does not pass for a couple of reasons.

First of all, the tm_yday field is set to an invalid value. The
strftime() function doesn't behave consistently across platforms in case
the values in the tm structure are incoherent. Fix up this field to have
the value 121, which corresponds with tm_mday, tm_mon and tm_year. This
of course affects the output of time_put for some modifiers, so update
the tests accordingly.

Second, some of the tests actually use modifiers that are only present
on BSD derived systems. They are not part of the C standard/POSIX.
Simply remove them.

Finally, some of the tests actually use invalid modifiers, causing a
malformed format string to be passed to strftime(). Remove these tests
as well.

13858ee056 [libcxx] Add <experimental/tuple> header for LFTS.
Summary:
This patch adds the `<experimental/tuple>` header (almost) as specified in the latest draft of the library fundamentals TS.

The main changes in this patch are:

1. Added variable template `tuple_size_v`
2. Added function `apply(Func &&, Tuple &&)`.
3. Changed `__invoke` to be `_LIBCPP_CONSTEXPR_AFTER_CXX11`.

The `apply(...)` implementation uses `__invoke` to invoke the given function. `__invoke` already provides the required functionality. Using `__invoke` also allows `apply` to be used on pointers to member function/objects as an extension. In order to facilitate this `__invoke` has to be marked `constexpr`. 



Test Plan:
Each new feature was tested. 

The test cases for `tuple_size_v` are as follows:
1. tuple_size_v.pass.cpp
  - Check `tuple_size_v` on cv qualified tuples, pairs and arrays.
2. tuple_size_v.fail.cpp
  - Test on reference type.
3. tuple_size_v_2.fail.cpp
  - Test on non-tuple
4. tuple_size_v_3.fail.cpp
  - Test on pointer type.

The test cases for tuple.apply are as follows:

1. arg_type.pass.cpp
   - Ensure that ref/pointer/cv qualified types are properly passed.
2. constexpr_types.pass.cpp
   - Ensure constexpr evaluation of apply is possible for `tuple` and `pair`.
3. extended_types.pass.cpp
   - Test apply on function types permitted by extension.
4. large_arity.pass.cpp
   - Test that apply can evaluated on tuples and arrays with large sizes.
5. ref_qualifiers.pass.cpp
   - Test that apply respects ref qualified functions.
6. return_type.pass.cpp
   - Test that apply returns the proper type.
7. types.pass.cpp
   - Test apply on function types as required by LFTS.

8e706d2c3e [libcxx] Move tuple_size and tuple_element overloads for pair and array out of !defined(_LIBCPP_HAS_NO_VARIADICS) block.
Summary:
There is no reason to guard `tuple_size`, `tuple_element` and `get<I>(...)` for pair and array inside of `<__tuple>` so that they are only available when we have variadic templates.
This requires there be redundant declarations and definitions. It also makes it easy to get things wrong.

For example the following code should compile (and does in c++11).
```
#define _LIBCPP_HAS_NO_VARIADICS
#include <array>

int main()
{
  static_assert((std::tuple_size<std::array<int, 10> volatile>::value == 10), "");
}
```

This patch lifts the non-variadic parts of `tuple_size`, `tuple_types`, and `get<I>(...)` to the top of `<__tuple>` where they don't require variadic templates. This patch also removes `<__tuple_03>` because there is no longer a need for it.

b33ae5ba7d Add option to disable access to the global filesystem namespace.
Systems like FreeBSD's Capsicum and Nuxi CloudABI apply the concept of
capability-based security on the way processes can interact with the
filesystem API. It is no longer possible to interact with the VFS
through calls like open(), unlink(), rename(), etc. Instead, processes
are only allowed to interact with files and directories to which they
have been granted access. The *at() functions can be used for this
purpose.

This change adds a new config switch called
_LIBCPP_HAS_NO_GLOBAL_FILESYSTEM_NAMESPACE. If set, all functionality
that requires the global filesystem namespace will be disabled. More
concretely:

- fstream's open() function will be removed.
- cstdio will no longer pull in fopen(), rename(), etc.
- The test suite's get_temp_file_name() will be removed. This will cause
  all tests that use the global filesystem namespace to break, but will
  at least make all the other tests run (as get_temp_file_name will not
  build anyway).

It is important to mention that this change will make fstream rather
useless on those systems for now. Still, I'd rather not have fstream
disabled entirely, as it is of course possible to come up with an
extension for fstream that would allow access to local filesystem
namespaces (e.g., by adding an openat() member function).

761d98d2f7 Copy data files to the remote runner.
Summary:
The data files for any given test will be in the same directory as the
source with a file name that matches *.dat. To make these available to
tests running remotely (such as over adb or ssh), copy them into the
test's remote working directory.

Note that we will perform more copies than we actually need. The data
files in the directory may only be used by one of the tests, but will
be copied for all tests in the same directory.

This patch also moves the remote test binary into the working
directory (previously it was only invoked from the working directory
rather than existing in it).

681abae7dc Also use LC_C_LOCALE on CloudABI.
Before I discovered that NetBSD provides a permanent handle to the C
locale called LC_C_LOCALE, I also added support for this to CloudABI
under the name LC_POSIX_LOCALE. I've renamed it to LC_C_LOCALE to
improve compatibility.

4c42c4e688 Enable _LIBCPP_LOCALE__L_EXTENSIONS on CloudABI.
CloudABI provides the _l() functions that are part of POSIX.1-2008, but
also the extensions that are available on systems like OS X and *BSD
(scanf_l, printf_l, etc).

21876f739e Don't include <sys/sysctl.h> on CloudABI.
As CloudABI does not provide sysctl(), this header is not present. Make
thread.cpp build correctly (and pass all tests) by not including the header.

e5a356a891 Print log/error messages on stderr, not stdout
There are a couple of places where libc++ prints log/error messages to
stdout on its own. This may of course interfere with the output
generated with applications. Log/error messages should be directed to
stderr instead.

63e70b67eb Add support for arc4random() to random_device.
Nuxi CloudABI (https://github.com/NuxiNL/cloudlibc) does not allow
processes to access the global filesystem namespace. This breaks
random_device, as it attempts to use /dev/{u,}random. This change adds
support for arc4random(), which is present on CloudABI.

In my opinion it would also make sense to use arc4random() on other
operating systems, such as *BSD and Mac OS X, but I'd rather leave that
to the maintainers of the respective platforms. Switching to
arc4random() does change the ABI.

This change also attempts to make some cleanups to the code. It adds a
single #define for every random interface, instead of testing against
operating systems explicitly.

As discussed, also validate the token argument to be equal to
"/dev/urandom" on all systems that only provide pseudo-random numbers.
This should cause little to no breakage, as "/dev/urandom" is also the
default argument value.
