Move rejection of `#`, `<`, and `>` characters in outputs and byproducts
to a generate-time check.  This removes the front-end check that
disallowed generator expressions.  The generators have already been
updated to handle them.

Fixes: #12877

Each source compilation generates a dependencies file. These dependencies
files are consolidated in one file per target. This consolidation is done
as part of command 'cmake -E cmake_depends` launched before evaluation of
makefile dependency graph.

The consolidation uses the same approach as `CMake` dependencies management.

Defer adding this command until post-3.19 development so that it
has more time to mature before being included in a release.

Fixes: #19568, #20922

On systems with older GNU system compilers, the Intel C++ compiler does
not define `__cplusplus` to any version newer than C++11.  This
prevented `bootstrap` from detecting that a given C++ standard flag has
enabled C++17 mode in the compiler.  In commit 033a4b12 (bootstrap:
Extend C++17 check for our cast functions, 2019-12-14,
v3.17.0-rc1~291^2) we added a preprocessor condition to attempt to
detect C++17 mode in the Intel compiler on such systems by looking
for `__cpp_if_constexpr`.  However, on systems with a modern GNU
system compiler, that definition is available even in C++11 mode.

Switch to using `__cpp_deduction_guides` to detect C++17 mode for the
Intel C++ compiler.  That seems to be defined exclusively in C++17 mode
regardless of the version of the system compiler.

Add `bootstrap` options needed since commit 0b872fd4 (nghttp2: Build
the library within CMake for use by our curl, 2020-04-01,
v3.18.0-rc1~408^2~2).

Support bootstrapping on older systems where our bundled
version libuv does not compile (.e.g Centos5, see #19086 and #19311).
Add a `--bootstrap-system-libuv` option to use the system-provided
libuv even for the bootstrap binary itself.

Refactored out of cmMakefile

GitLab now uses a `/-/` component between the `group/project` part of
the URL and the `{issues,merge_requests,tree}` part so that it can
support `group/subgroup/project` with arbitrary depth.

The former is more portable.

Since commit 380bd70c (bootstrap: implement cmake_toupper() using tr,
2017-06-07, v3.10.0-rc1~548^2~2) we use `tr` to convert from lower to
upper case.  However, the character classes `[:lower:]` and `[:upper:]`
result in a "Bad string" error message on Solaris.  Use `[a-z]` and
`[A-Z]` instead.

These standard flags are the same for CXX, OBJCXX and CUDA.
Refactor them into a single macro to reduce duplication and so we can easily reuse them.

Updated bootstrap script to search in the general Clang module instead of the language-specific.

Fixes: #20197

In commit fc3b4caa (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 6e613ff3 (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

Use the output checks for byproducts of add_custom_command also for byproducts
of add_custom_target.

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.
