Added new USES_TERMINAL option to the ExternalProject_Add_Step
function. This option passes USES_TERMINAL to the underlying
add_custom_command call so that the Ninja console pool is used.
Also, corresponding new USES_TERMINAL_<step> options were added
to the ExternalProject_Add function.
Justification: if using Ninja with a CMake superbuild, it's often
desirable to limit the superbuild to ONE sub-Ninja process at a
time to avoid oversubscribing the CPU. Using the console pool also
makes it easy to monitor the progress of the sub-Ninja process.
Independent USES_TERMINAL_<step> arguments are passed to
ExternalProject_Add instead of one USES_TERMINAL argument that
controls everything. Users may wish to run some steps in parallel
but not others (e.g. parallelize configure but not build).
This was added without explanation by commit v2.8.2~1138 (Add initial XL
C compiler flags for safer builds, 2009-09-30). It is not consistent
with our default C++ flags for XL and disables several optimizations, so
drop it from our default flags for C.

Add a TestLoad setting to CTest that can be set via a new --test-load
command-line option, CTEST_TEST_LOAD variable, or TEST_LOAD option to
the ctest_test command. Teach cmCTestMultiProcessHandler to measure
the CPU load and avoid starting tests that may take more than the
spare load currently available. The expression
<current_load> + <test_processors> <= <max-load>
must be true to start a new test.

The original implementation of the RUN_SERIAL test property worked by
having such a test consume all available processors. Instead use an
explicit flag to indicate that a serial test is running. This avoids
artificially inflating the number of processors a test is expected to
consume.
Move the Ld invocation match expression from CMakeDetermineCompilerId
into CMakeDetermine{C,CXX,Fortran}Compiler so that it can be specified
on a per-language basis.
Replace caret-headers with double-quote-headers and replace dash-headers
with caret-headers. This makes the headers match their level of nesting
according to our documentation style guide in cmake-developers(7).
