FindFreetype: Find ftheader.h with Freetype 2.5
CMakeDetermineCompilerId: Fix compiler line match for Xcode 5.1

Xcode 5.1 output no longer puts "./" in the path to the linker output
for the CompilerId test binary.  Update our regex to match the path
with or without the component.
libarchive: Port upstream issue 320 second fix

Port upstream commit 6cf33c93 (Issue 320: Rewrite (again) to avoid
the left shift that CLang dislikes so much, 2013-12-07) into CMake.

FindFreetype: Detect version string with Freetype 2.5
FindFreetype: Remove duplicates in FREETYPE_INCLUDE_DIRS

In Freetype 2.5 the paths for FREETYPE_INCLUDE_DIR_ft2build and
FREETYPE_INCLUDE_DIR_freetype2 are the same
libarchive: Use ARCHIVE_LITERAL_ULL to add ULL integer suffix

The macro maps to an implementation that works on older compilers
when necessary.
Don't search for IMPORTED_LOCATION of INTERFACE_LIBRARY (14636)

The INTERFACE_LIBRARY type does not have any LOCATION at all, so
return early from GetMappedConfig. GetMappedConfig is called from
two locations, one of which already pre-checks the INTERFACE_LIBRARY
case. Remove that pre-check and handle that case inside the method
instead.
Remove INTERFACE build targets.

Commit b04f3b9a (Create make rules for INTERFACE_LIBRARY
targets., 2013-08-21) extended the makefile generator to create
build targets for INTERFACE_LIBRARY targets. No other generators
were extended with this feature.

This conflicts with the feature of whitelisting of target properties
read from INTERFACE_LIBRARY targets. The INTERFACE_* properties
of the INTERFACE_LIBRARY may legitimately contain TARGET_PROPERTY
generator expressions for reading properties from the 'head target'.
The 'head target' would be the INTERFACE_LIBRARY itself when creating
the build rules for it, which means that non-whitelisted properties
would be read.
Define QT_NO_DEBUG for non-debug use of Qt 4.
FindSubversion: Use TortoiseSVN registry key to locate svn

If TortoiseSVN is not installed in the default path, the svn executable
installed by TortoiseSVN is not found.
Using the registry key should always find it.
Avoid certain actions on IMPORTED targets.

As we're iterating over IMPORTED targets now, handle them in
the loop body. The existing behavior is harmless because generally
nothing is done anyway for IMPORTED targets in these code paths,
because they do not have sources for example.
Constify handling of target dependencies.
Constify handling of link targets.
Constify cmGeneratorTarget access.
cmLocalGenerator: Constify target definitions access
Autogen: Split AutoRcc handling into two methods

The initialize method changes the target, whereas the setup method
does not.
Constify autogen handling.
Use a config-specific moc parameters file, if needed.
Help: Note that COMPATIBLE_INTERFACE_ properties may be origin-debugged.

Link to other properties mentioned in the docs already.
Tests: allow valgrind test to pass with symlinked build dir
