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.
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.
The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.
The first regression resulted in endless looping due to unrun test
dependencies. The second regression prioritized all tests with dependencies
in serial test runs.
Note it is still possible for CTest to start more than the number of
processes specified by PARALLEL_LEVEL, but this prevents the number of
tests to start from being unbounded because of overflow.
Using sort results in a possibly-modified sorting
when all elements are "tied" - use stable_sort instead
to preserve the original ordering of tied elements.
A cycle exists when the DFS returns to the root node, not just when
multiple paths lead to the same node.

This command allows a user to quickly see the list of all available
test labels. The labels are also printed in verbose show only mode,
alongside their corresponding tests.
Change types of local variables, or casting, or re-arrange
expressions to get rid of "conversion may alter value" warnings
as seen on recent dashboard submissions from londinium.kitware.
Allow the user to set the CMake variable CTEST_COST_DATA_FILE, which will be used to store the cost data from test runs. If not set, defaults to the original location in the build tree Testing/Temporary dir.
