LOG: [libc++] [docs] Migrate C++ status pages to RestructuredText (RST).
Currently, papers and issues are in separate .csv files (that is easier to update), but I can put them inline.Transforming current html tables into rst are done by the script (attached to the patch FYI but I'll remove it before committing).
I'll of course update RST files before committing to match any modifications that may happen in master branch.
This patch moves the status pages in www/ to RST format in docs/.
It also does some other minor changes: fix copyright year and broken comment end, adds substitutions for coherence (and add colors, but that can be removed easily).
It adds as well redirects from old to new status pages.

+Overview
+================================
+
+In April 2013, the C++ standard committee approved the draft for the next version of the C++ standard, initially known as "C++1y".
+
+The draft standard includes papers and issues that were voted on at the previous three meetings (Kona, Portland, and Bristol).
+
+In August 2014, this draft was approved by ISO as C++14.
+
+This page shows the status of libc++; the status of clang's support of the language features is `here <https://clang.llvm.org/cxx_status.html#cxx14>`__.
+
+The groups that have contributed papers:
+
+- CWG - Core Language Working group
+- LWG - Library working group
+- SG1 - Study group #1 (Concurrency working group)

+Overview
+================================
+
+In November 2014, the C++ standard committee created a draft for the next version of the C++ standard, initially known as "C++1z".
+In February 2017, the C++ standard committee approved this draft, and sent it to ISO for approval as C++17.
+
+This page shows the status of libc++; the status of clang's support of the language features is `here <https://clang.llvm.org/cxx_status.html#cxx17>`__.
+
+.. attention:: Features in unreleased drafts of the standard are subject to change.
+
+The groups that have contributed papers:
+
+- CWG - Core Language Working group
+- LWG - Library working group
+- SG1 - Study group #1 (Concurrency working group)
+
+.. note:: "Nothing to do" means that no library changes were needed to implement this change.

+Overview
+================================
+
+In July 2017, the C++ standard committee created a draft for the next version of the C++ standard, known here as "C++2a" (probably to be C++20).
+
+This page shows the status of libc++; the status of clang's support of the language features is `here <https://clang.llvm.org/cxx_status.html#cxx2a>`__.
+
+.. attention:: Features in unreleased drafts of the standard are subject to change.
+
+The groups that have contributed papers:
+
+- CWG - Core Language Working group
+- LWG - Library working group
+- SG1 - Study group #1 (Concurrency working group)
+
+.. note:: "Nothing to do" means that no library changes were needed to implement this change.

+
+ .. [#note-P0202] P0202: The missing bits in P0202 are in ``copy`` and ``copy_backwards`` (and the ones that call them: ``copy_n``, ``set_union``, ``set_
diff erence``, and ``set_symmetric_
diff erence``). This is because the first two algorithms have specializations that call ``memmove`` which is not constexpr. See `Bug 25165 <https://bugs.llvm.org/show_bug.cgi?id=25165>`__
+ .. [#note-P0600] P0600: The missing bits in P0600 are in |sect|\ [mem.res.class], |sect|\ [mem.poly.allocator.class], and |sect|\ [container.node.overview].
+
+ .. [#note-P0619] P0619: Only ``std::allocator`` part is implemented.

- <!--*********************************************************************-->
-
- <p>In April 2013, the C++ standard committee approved the draft for the next version of the C++ standard, initially known as "C++1y".</p>
- <p>The draft standard includes papers and issues that were voted on at the previous three meetings (Kona, Portland, and Bristol)</p>
- <p>In August 2014, this draft was approved by ISO as C++14</p>
- <p>This page shows the status of libc++; the status of clang's support of the language features is <a href="https://clang.llvm.org/cxx_status.html#cxx14">here</a>.</p>
-
- <p>The groups that have contributed papers:
- <ul>
- <li>CWG - Core Language Working group</li>
- <li>LWG - Library working group</li>
- <li>SG1 - Study group #1 (Concurrency working group)</li>
- </ul>

- <p>In November 2014, the C++ standard committee created a draft for the next version of the C++ standard, initially known as "C++1z".</p>
- <p>In February 2017, the C++ standard committee approved this draft, and sent it to ISO for approval as C++17</p>
- <p>This page shows the status of libc++; the status of clang's support of the language features is <a href="https://clang.llvm.org/cxx_status.html#cxx17">here</a>.</p>
-
- <p>Reminder: Features in unreleased drafts of the standard are subject to change.</p>

- <h1>libc++ C++2a Status</h1>
- <!--*********************************************************************-->
-
- <p>In July 2017, the C++ standard committee created a draft for the next version of the C++ standard, known here as "C++2a" (probably to be C++20).</p>
- <p>This page shows the status of libc++; the status of clang's support of the language features is <a href="https://clang.llvm.org/cxx_status.html#cxx2a">here</a>.</p>
-
- <p>Reminder: Features in unreleased drafts of the standard are subject to change.</p>
-
- <p>The groups that have contributed papers:
- <ul>
- <li>LWG - Library working group</li>
- <li>CWG - Core Language Working group</li>
- <li>SG1 - Study group #1 (Concurrency working group)</li>
- </ul>
