last_write_time(sym, new_time) changes the modification time of the file
referenced by the symlink. But reading through the symlink may change the
symlinks's access time.
This meant the previous test that checked that the symlinks access
time was unchanged was incorrect and made the test flaky.
This patch removes this test (there really is no non-flaky way
to test that the new access time coorisponds to the time at which
the symlink was last dereferenced). This should unflake the test.

path("/dir/").lexically_relative("/dir"); now returns "." instead of ""

This prevents things like:
using namespace std::filesystem;
auto x = L"a/b" == std::string("a/b");

This patch implements path::compare according to the current spec. The
only observable change is the ordering of "/foo" and "foo", which orders
the two paths based on having or not having a root directory (instead
of lexically comparing "/" to "foo").

NetBSD also uses tv_sec==-1 as error status indicator, and does not
support setting such a value.

This patch implements the <filesystem> header and uses that
to provide <experimental/filesystem>.
Unlike other standard headers, the symbols needed for <filesystem>
have not yet been placed in libc++.so. Instead they live in the
new libc++fs.a library. Users of filesystem are required to link this
library. (Also note that libc++experimental no longer contains the
definition of <experimental/filesystem>, which now requires linking libc++fs).
The reason for keeping <filesystem> out of the dylib for now is that
it's still somewhat experimental, and the possibility of requiring an
ABI breaking change is very real. In the future the symbols will likely
be moved into the dylib, or the dylib will be made to link libc++fs automagically).
Note that moving the symbols out of libc++experimental may break user builds
until they update to -lc++fs. This should be OK, because the experimental
library provides no stability guarantees. However, I plan on looking into
ways we can force libc++experimental to automagically link libc++fs.
In order to use a single implementation and set of tests for <filesystem>, it
has been placed in a special `__fs` namespace. This namespace is inline in
C++17 onward, but not before that. As such implementation is available
in C++11 onward, but no filesystem namespace is present "directly", and
as such name conflicts shouldn't occur in C++11 or C++14.
