Policies affecting the behavior of CMake-provided macros and functions
need to be able to get the policy setting as of the call site rather
than the definition site. Add an undocumented option to do this.
Refactoring in commit v3.4.0-rc1~321^2 (cmMakefile: Remove special
handling of INCLUDE_REGULAR_EXPRESSION, 2015-04-04) accidentally broke
propagation of the include regex to subdirectories. Refactoring in
commit v3.5.0-rc1~319^2~1 (cmState: Initialize properties immediately,
2015-10-07) moved maintenance of this value from `cmMakefile` to
`cmStateSnapshot`.
Restore propagation of the `INCLUDE_REGULAR_EXPRESSION` to
subdirectories and add a test to cover it.
Fixes: #17676
In commit 0bbd993f (Make CMAKE_HOST_SYSTEM_NAME available in scripting
context, 2016-12-26) we added a call to `uname` that checks for a zero
return value. However, on Solaris the `uname(2)` manual [1] says that
on success a non-negative value is returned. Fix our return code check
so that we detect the `SunOS` name correctly.

Port dependents to the new locations as needed.
Leave behind a cmState.h include in cmListFileCache to reduce noise. It
is removed in a following commit.
