Before this change, install rules created by add_subdirectory()
would be executed after all of the top-level install rules, even
if they were declared before the top-level rules. This change
adds a new policy, CMP0082, which interleaves the add_subdirectory()
install rules with the other install rules so they are run in the
correct order.
Avoid exposing the item name implicitly as std::string. When the item
is a target, avoid storing a second copy of its name.
Most link item construction is paired with calls to `FindTargetToLink`
to get the possible target pointer. Rename these methods to
`ResolveLinkItem` and refactor them to construct the entire item.
Add `clang` and `clang++` after the corresponding `gcc` and `g++`
candidates. Otherwise it is not tried on platforms where we do not
enumerate the toolchain pair candidates.

Some versions of clang 5 (with libc++) have a problem with
`unordered_map` under `-std=gnu++1z`:
/usr/include/c++/__hash_table:1134:43: error: conflicting types for '__hash_table<_Tp, _Hash, _Equal, _Alloc>'
Include `unordered_map` in our test source so that we reject this
combination and fall back to an older C++ standard flag.

On UNIX, build only the parts of libuv we need for the filesystem,
process, and poll abstractions using the POSIX poll() backend. This
avoids many platform-specific conditions. On Windows, build all of
libuv; there are no conditional alternatives anyway.
Since commit v3.9.0-rc1~281^2 (Use quotes for non-system includes,
2017-04-11) we include `cmConfigure.h` via `""` instead of `<>`.
This breaks the `bootstrap` script when run more than once in an
in-source build. In that case `cmConfigure.h` is generated next
to the source files that include it, so `""`-style includes prevent the
`Bootstrap.cmk/cmConfigure.h` file from being included during bootstrap.
Fix this by teaching the bootstrap script to remove any `cmConfigure.h`
that may have been generated by an earlier run in an in-source build.
Fixes: #17082
Some compilers have enough features enabled in their default modes to
pass our simple C++11 unique_ptr check but do not enable enough to build
CMake. Poison this case so that we choose one of the explicit `-std=`
options for such compilers.

CMake can now compile as C++11 on all supported platforms. Check that
std::unique_ptr is available and fail early if missing. This will allow
us to use C++11 more broadly in CMake's implementation (previously it
was restricted to the serve mode implementation).
Co-Author: Daniel Pfeifer <daniel@pfeifer-mail.de>
CMake will soon require both C++11 and libuv to build. Neither of
these works on HP-UX, so unfortunately we need to drop support for
the platform until someone can get them working.
