In commit fc3b4caa2e (Memory management: cast functions for managed pointers,
2019-11-18) we added a check to `Source/Checks/cm_cxx17_check.cpp` to avoid
using C++17 mode on a compiler that does not support all our C++17 usage.
Add the check to our bootstrap script too.
In commit 6e613ff399 (bootstrap: Add infrastructure to detect threading
flags, 2017-11-28, v3.11.0-rc1~281^2~1) an extra level of nesting was
added to the selection loop, but the inner-most `break` command used to
exit the loop on success was not updated. This caused the outer-most
loop to iterate unnecessarily and repeatedly try the same compilers
again. In the case of compilers requiring a `-std=` flag, this may have
caused the oldest standard to be used instead of the newest.
* Added a fairly comprehensive test suite
* Separated the graph traversal logic from the Graphviz generation
code by introducing a new class, cmLinkItemsGraphVisitor{.h,cxx}
* Made the graph traversal logic less ad-hoc by using existing
methods in the GlobalGenerator; this fixed a few bugs
* Added support for new target types: custom targets, object
and unknown libraries
* Improved support for ALIAS libraries by showing the alias(es)
in the graph
* Introduced new flags to control those new libraries (consistent
with existing flags)
* Updated the documentation
* Removed useless setting to set graph type in dot file
* Improved the node/edge shapes (nicer, more consistent)
* Added a legend to the graph
* Some refactoring and cleanup of the Graphviz generation code
* Added test and fix for issue 19746

Revise for future removal of the early rejection checks on HP-UX.
Our code may now work with GCC 4.9 on HP-UX when manually using
`env CXXFLAGS=-D_GLIBCXX_USE_C99` to make the C++11 `std::to_string`
available on this platform. However, without nightly testing we
cannot officially enable support for the platform.

Provide a standardized way to handle the C++ "standard" headers
customized to be used with current CMake C++ standard constraints.
Offer under directory `cm` headers which can be used as direct
replacements of the standard ones. For example:
#include <cm/string_view>
can be used safely for CMake development in place of the `<string_view>`
standard header.
Fixes: #19491
Remove -DCMAKE_BUILD_WITH_CMAKE from Source/CMakeLists.txt. Remove
CMAKE_BOOTSTRAP from bootstrap's cmConfigure.h. Add -DCMAKE_BOOTSTRAP
to all bootstrap sources, and remove the Unix specialization of
CMAKE_BOOTSTRAP in libuv (a review of the libuv code suggests that
this will not have an effect on the Windows build.)

In commit a605bf438e (Extend C++17/C++14 feature checks to cover more
standard library APIs, 2019-02-27, cpp-modules-20190312.1~52^2~1) we
added checks to the main build of CMake to verify C++14 capabilities
before using C++14 flags to build. Add these to the bootstrap check
too.

Previously CMake used fairly naive logic to determine when to do
device linking which caused unnecessary device linking to occur
frequently. We now use a more exhaustive algorithm to determine
when we have a need for device linking.
Fixes: #19238
This class is ultimately intended as a replacement for cmsys::Process.
It spawns a series of processes using libuv, piping the output of each
command into the next.
Note: input support has not yet been implemented because write
support has not yet been implemented on cmUVStreambuf.
The new cmFileTime class stores the file modification time as an OS independent
nanosecond count. Its main use is to load and compare file modification times
in nanosecond and second resolution.
In order to keep infinitely-recursive scripts from causing a stack
overflow in the CMake executable, CMake now imposes a maximum
recursion limit before issuing an error message. The limit can be
adjusted at runtime with CMAKE_MAXIMUM_RECURSION_DEPTH.
Fixes: #18694
