Teach Sphinx and our own install rules to skip a `Help/dev` directory.
This will give us a place to put developer-only documentation that

We've ported our libuv to this platform so we can build it now.

The switch to use UTF-8 encoding has been defaulted to on for quite some
time since commit v3.2.0-rc1~116^2 (Encoding: Switch to use UTF-8
internally by default on Windows, 2014-12-26).

Use KWSys ConsoleBuf to replace the `streambuf` on `std::cout` and
`std::cerr` so that process output can be encoded correctly for display
in a Windows console.

Expat is built anyway.

Older versions of libuv did not have the uv_loop_close API.  It first
showed up in unstable releases ~ v0.11.20 but was not available in
a stable release until v1.0

Add a `CMake_TEST_SERVER_MODE` option that can be set in testing builds
to enable/disable server mode tests explicitly.  This will allow testing
in combination with `CMake_TEST_EXTERNAL_CMAKE` or for server mode to be
built on systems that have a python version that cannot run the test.

Provide a way for scripts building CMake to enable server mode
explicitly and assume the risk of a build failure if it is not
supported.  This will allow such scripts to ensure that server
mode is available if the build succeeds.  It also allows scripts
to explicitly disable server mode even if it would be supported.

The latter is a better name for making it a public-facing option.

CMake is frequently built from source via bootstrap.
There is no reason we cannot support server mode.

Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool.  Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience.  Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.

Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices.  It also references version control
history for more precise information.  Therefore we no longer need to spell
out the list of Contributors in each source file notice.

Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing".  The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.

Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically.  Manually fix up shebang lines and trailing
newlines in a few files.  Manually update the notices in a few files that the
script does not handle.

Adds a bare-bones cmake-server implementation and makes it possible
to start that with "cmake -E server".

Communication happens via stdin/stdout for now.

Protocol is based on Json objects surrounded by magic strings
("[== CMake Server ==[" and "]== CMake Server ==]"), which simplifies
Json parsing significantly.

This patch also defines an interface used to implement different
versions of the protocol spoken by the server, but does not include
any protocol implementaiton.

This will enable use of features such as ALIAS targets within CMake's
own build.
