Call sites such as those in the VS global generator that are used only
to reject per-config sources will now allow per-config object library
objects. The corresponding generators have already been taught to deal
with per-config object library files. Remaining call sites do not need
object library files anyway.
This will later allow `$<TARGET_OBJECTS:...>` generator expressions to
evaluate to values that vary by configuration (e.g. because each
configuration has its own object files).
Add internal infrastructure for looping over all sources for all
configurations and generating each source with exclusion marks
for configurations in which they do not participate. This does
not yet make per-config sources available in general but does
set up some of the needed infrastructure.
Unfortunately doing this cleanly will require major refactoring of both
the VS 7-9 generators and the VS 10+ generators (for separate reasons).
Instead add some extra internal structures to carry information where we
need it.
We can do this only with Xcode 5 and above where we list the object
library files in the per-config link line value. On older Xcode
versions we list the object files as sources so that dependencies work
correctly, but that does not allow per-config objects. (Xcode may allow
per-config source exclusion but only by base name.)
Multi-config generators like VS and Xcode need to loop over all the
source files first and then handle per-config information within
each one. Teach cmGeneratorTarget to provide such a view.

Make sure that `#include <cmConfigure.h>` is followed by an empty line
in header files. This is necessary to make sure that changing <> to ""
does not affect the include ordering of clang-format.
Automate with:
git grep -l '#include <cmConfigure.h>' | grep -v '.cxx$' \
| xargs sed -i '/#include <cmConfigure.h>/ { N; N; s/\n\{1,2\}/\n\n/ }'
It is quite often the project description has used in a real world software.
Examples include:
* part of a help screen of the application
* builtin resources (`*.rc` files, data for "About" dialog of a GUI app, & etc)
* most generators for CPack can use it
* it could be used by documentary software (Doxygen, Sphinx) which is usually
integrated to CMake based projects via `add_custom_target()`
Now `project()` call learned an optional `DESCRIPTION` parameter with a
short string describing a project. Being specified, it would set the
`PROJECT_DESCRIPTION` variable which could be used in `configure_file()`
or whatever user wants. Also `PROJECT_DESCRIPTION` is a default value
for `CPACK_PACKAGE_DESCRIPTION_SUMMARY`.
Object library files are already included by `GetExternalObjects`
and `GetConfigCommonSourceFiles` so we don't need to call
`UseObjectLibraries` to get them.
