Brad King a41c0a9dcb Do not warn by default when policy CMP0025 or CMP0047 is not set
These policies are triggered by the use of a particular compiler rather
than outdated CMake code in a project.  Avoid warning in every project
that enables a language by not displaying the policy warning by default.
Add variable CMAKE_POLICY_WARNING_CMP<NNNN> to control the warning
explicitly; otherwise enable the warning with --debug-output or --trace.

This breaks with strict policy convention because it does not provide
developers with any warning about the behavior change by default.
Existing projects will continue to build without a warning or change in
behavior.  When a developer changes the minimum required version of
CMake in a project to a sufficiently high value (3.0), the project will
suddenly get the new compiler id and may break, but at least the
breakage comes with a change to the project rather than the version of
CMake used to build it.

Breaking strict policy convention is worthwhile in this case because
very few projects will be affected by the behavior change but every
project would have to see the warning if it were enabled by default.

Brad King d339653eaf Help: Revise and format policy CMP0025 and CMP0047 docs
Add inline reST markup as appropriate.  Word CMP0047 docs more like
those of CMP0025.  State explicitly that the policies must be set
before the project or enable_language command calls.

Brad King aab11bcab4 Help: Change version 3.0.0 -> 3.0 in policy docs
Starting with 3.0 we will use only two components for the feature level,
and policies are only ever introduced with a bump to the feature level
version.

Brad King 1873205a6e Update CMP0024/CMP0025/CMP0026 release version
These policies were introduced after 2.8.12 in anticipation of 2.8.13.
However, we've now decided the next release will be 3.0.0, so update the
version of introduction accordingly.
