Allow setting build properties based on the features available
for a target. The availability of features is determined at
generate-time by evaluating the link implementation.
Ensure that the <LANG>_STANDARD determined while evaluating
COMPILE_FEATURES in the link implementation is not lower than that
provided by the INTERFACE of the link implementation. This is
similar to handling of transitive properties such as
POSITION_INDEPENDENT_CODE.

When we kill a child we send SIGSTOP first so that we can traverse its
child processes recursively. On unwinding the recursion we then send
SIGKILL. Current Cygwin has trouble when both signals are sent in quick
succession by the parent process. Add a usleep(1) after sending the
first signal to give up our time slice and give Cygwin a chance to
process the first signal before sending the second.

Update cmake_minimum_required calls in CMakeLists.txt in Modules and in
CMakeLists.txt generated by other modules, so that they are always in
sync with current CMake version.
Some modules change CMake minimum required version when they are
included. For example:
cmake_minimum_required(VERSION 2.8.12)
message("${CMAKE_MINIMUM_REQUIRED_VERSION}")
include(CheckTypeSize)
message("${CMAKE_MINIMUM_REQUIRED_VERSION}")
will produce the following output:
2.8.12
2.6
This patch ensures that when you include a CMake module the minimum
required version and the policies set are left unchanged.

40b9cd0f CMP0022: Fix link language propagation in NEW behavior
42bbf130 CMP0022: Fix link language propagation in NEW behavior
Previously when linking the intermediate link file for separable compilation
the CUDA_NVCC_FLAGS* were not used. This caused tremendous confusion when
using this feature, and I consider it to be a bug. This change should fix
this.
The languages used in compiling STATIC libraries need to be propagated
to dependents regardless of the settings of INTERFACE_LINK_LIBRARIES or
CMP0022. They are independent of the libraries in the link interface.
Prior to commit v2.8.12~192^2~2 (Introduce the INTERFACE_LINK_LIBRARIES
property, 2013-06-04) the cmTarget::ComputeLinkInterface code path for
"explicitLibraries" could never be taken for STATIC libraries, so the
logic to propagate languages existed only in the non-explicitLibraries
code path. After that commit, INTERFACE_LINK_LIBRARIES could be set for
STATIC libraries to cause the "explicitLibraries" code path to be taken.
The commit also left the old non-explicitLibraries code path conditional
on CMP0022 not being set to NEW. Thus link language propagation was
left missing from two cases by that commit.
The explicitLibraries code path was fixed to propagate languages by
commit v2.8.12~149^2~1 (cmTarget: Fix iface libraries and languages for
static libraries, 2013-07-26). However, the non-explicitLibraries case
was never taught to propagate languages when CMP0022 is set to NEW. Fix
that now. Factor the logic to propagate link languages out of the link
interface libraries conditions so that it always occurs. Update
Tests/Fortran to set CMP0022 to NEW to test this case (because the test
passes only if link language propagation works).
