e96d6a1fb7 Implement P0430R2 - File system library on non-POSIX systems. 
This patch implements P0430R2, who's largest change is adding the path::format
enumeration for supporting path format conversions in path constructors.

However, since libc++'s filesystem only really supports POSIX like systems,
there are no real changes needed. This patch simply adds the format enum
and then ignores it when it's passed to constructors.

1e34c76d33 Implement filesystem NB comments, relative paths, and related issues. 
This is a fairly large patch that implements all of the filesystem NB comments
and the relative paths changes (ex. adding weakly_canonical). These issues
and papers are all interrelated so their implementation couldn't be split up
nicely.

This patch upgrades <experimental/filesystem> to match the C++17 spec and not
the published experimental TS spec. Some of the changes in this patch are both
API and ABI breaking, however libc++ makes no guarantee about stability for
experimental implementations.

The major changes in this patch are:

* Implement NB comments for filesystem (P0492R2), including:
  * Implement `perm_options` enum as part of NB comments, and update the
    `permissions` function to match.
  * Implement changes to `remove_filename` and `replace_filename`
  * Implement changes to `path::stem()` and `path::extension()` which support
    splitting examples like `.profile`.
  * Change path iteration to return an empty path instead of '.' for trailing
    separators.
  * Change `operator/=` to handle absolute paths on the RHS.
  * Change `absolute` to no longer accept a current path argument.

* Implement relative paths according to NB comments (P0219r1)

* Combine `path.cpp` and `operations.cpp` since some path functions require
  access to the operations internals, and some fs operations require access
  to the path parser.

a4fd0c9d61 Overhaul unique_ptr - Implement LWG 2801, 2905, 2520. 
This patch overhauls both specializations of unique_ptr while implementing
the following LWG issues:

* LWG 2801 - This issue constrains unique_ptr's constructors when the deleter type
  is not default constructible. Additionally it adds SFINAE conditions
  to unique_ptr<T[]>::unique_ptr(Up).

* LWG 2905 - This issue reworks the unique_ptr(pointer, /* see below */ deleter)
  constructors so that they correctly SFINAE when the deleter argument cannot
  be used to construct the stored deleter.

* LWG 2520 - This issue fixes initializing unique_ptr<T[]> from nullptr.
  Libc++ had previously implemented this issue, but the suggested resolution
  still broke initialization from NULL. This patch re-works the
  unique_ptr<T[]>(Up, deleter) overloads so that they accept NULL as well
  as nullptr.
