Since commit v3.8.0-rc1~251^2 (UseSWIG: Record generated java files as
custom command outputs, 2016-11-28) the generated `.java` files are
listed as sources in the call to `add_library` by swig_add_library.
They are listed only as the outputs of custom commands and not intended
for compilation as part of the library.

Since commit v3.8.0-rc2~28^2~2 (Utilities/Sphinx: Port cmake extension
to Sphinx 1.4, 2017-02-09) we use the `sphinx.version_info` tuple.
However, it was added in Sphinx v1.2 so the check breaks compatibility
with older versions. Revise our check to assume Sphinx pre-1.2 if the
version tuple does not exist.
The code
add_library(A OBJECT a.c)
target_sources(A PRIVATE $<TARGET_OBJECTS:A>)
used to crash CMake via infinite recursion while evaluating the
generator expression. Then the change in commit v3.9.0-rc1~266^2~1
(cmGeneratorTarget: Replace source classifier implementation,
2017-04-07) avoided the infinite recursion because GetKindedSources now
creates a map entry and initializes it once. If it is called again on
the same target during that initialization, the partially computed
results are returned. This is still wrong but does not crash.
Detect and diagnose this case instead.

Fixes: #16578
Add a release note corresponding to the environmental regression fixed
by commit v3.9.0-rc6~15^2~1 (VS: Fix GenerateDebugInformation values for
v140 and v141 toolsets, 2017-06-27).
This is needed for Xcode 9's "New Build System", whose release notes
mention "that output must be declared as an explicit output by the
script which generates it" in reference to outputs of custom script
build phases.
The change in commit v3.9.0-rc1~174^2~2 (CompileFeatures: Let STD
compile options be a list, 2016-10-05) did not change all the places we
add the language standard options. Expand the list in the other places.
Since commit v3.8.0-rc1~51^2~1 (TestDriver: calc NumTests at compile
time, 2017-01-24) we convert an expression that uses `sizeof()` to an
`int` as a compile-time constant. Some GCC versions warn about this
with `-Wconversion`. Add a cast to avoid the warning.
The logic added in commit v3.6.0-rc1~30^2 (Add a variable to specify
language-wide system include directories, 2016-05-24) to use
`CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES` incorrectly filters them by
`CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES`. Rather than recognizing
this, commit v3.8.0-rc1~60^2 (Android: Pass sysroot include directory
explicitly, 2017-01-20) worked around the problem by incorrectly
removing `/usr/include` from `CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES`
so it worked in `CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES`.
By not filtering out `/usr/include` from user-specified include
directories, we allow the code
include_directories(${CMAKE_SYSROOT}/usr/include)
to place the include directory too early on the command line.
Fix support for standard include directories to not be filtered by
implicit include directories, and do not remove `/usr/include` from the
list of implicit include directories for Android builds. Add a test
case to verify that an explicit `/usr/include` is ignored in favor
of the standard directory at the end.

Revert the main logic change of commit v3.9.0-rc1~192^2 (bindexplib: fix
constants symbols export, 2017-04-26) and its test case. Unfortunately
some constants may be provided by multiple object files with different
`@...` suffixes, leading to ambiguous references. Revert support
pending further investigation.
Fixes: #17045
In the `Visual Studio 15 2017` generator, if the `VS150COMNTOOLS`
environment variable points at a specific VS 2017 instance reported by
the Visual Studio Installer tool, use that as the preferred instance.

Fixes: #16846
Since commit v3.9.0-rc1~58^2 (find_package: shorten output for missing
package in config mode, 2017-05-09) we print only the one line
- Could NOT find Foo (missing: Foo_DIR)
when package Foo cannot be found in CONFIG mode and it is not REQUIRED.
However, in the case that package configuration files were found but not
used, this one line message leaves out important information. This can
happen when a package configuration file sets `Foo_FOUND` to `FALSE` or
when its package version file does not match the requested version.
Restore the longer message in these cases. Otherwise a seemingly valid
explicit `Foo_DIR` setting appears to be silently ignored even if it was
considered.
Fixes: #17029
The change in commit v3.9.0-rc1~464^2~8 (Autogen: Add AUTOMOC/UIC
support for generated source files, 2017-03-02) changes behavior of
existing projects that may not expect `AUTOGEN` on generated files and
do not yet set `SKIP_AUTOGEN` on them. Disable the behavior change for
now to fix the regression for CMake 3.9. We can restore it later with a
policy.
In order to keep the implementation and tests working, add an
undocumented property we can use in the tests to enable the behavior
before the policy is introduced.
