On some systems, ${QT_INCLUDE_DIR} is reported by gcc as a builtin
include search dir. Some projects use this information to extend
CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES.
In cmake 2.8.10 now the targets are queried for the include directories
they use. When they return the result, the include dirs contained in
CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES have been removed.
In cmake 2.8.9 and below the INCLUDE_DIRECTORIES directory property
was queried, where this had not been stripped.
So, in those projects which modify the implicit include dirs variable,
on systems where ${QT_INCLUDE_DIR} is reported by gcc, this directory,
e.g. /usr/lib/include/qt/, was not given anymore to moc. This made moc
not find required headers, so the build broke.
Simply giving the full CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES to moc
is no solution either, since moc can't handle some of the headers it
finds then (https://bugreports.qt-project.org/browse/QTBUG-28045).
So now cmake checks CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES, and if this
contains ${QT_INCLUDE_DIR}, and the target reports that it uses
${QT_QTCORE_INCLUDE_DIR} but not ${QT_INCLUDE_DIR}, ${QT_INCLUDE_DIR}
is added to the include dirs given to moc.

Pass the name of the requested generator to the generator factory,
which is now responsible to check if it can create a matching
generator for the name. This allows us to add more logic to the
factory in a next step, so that not every possible generator needs
to get registered explicit in cmake::AddDefaultGenerators().
Since ExtraGenerators does not contain items, which are in Generators
too, there is not change in behaviour. The benefit of this change is,
that the lookup in the Generators map is now only done once.
Since commit ca39c5cd (Optionally allow IMPORTED targets to be globally
visible, 2012-01-25) cmGlobalGenerator has a second member that tracks
targets with global scope. We must initialize the new 'ImportedTargets'
member wherever the old 'TotalTargets' member is initialized. Without
this initialization the ImportedTargets member is left with dangling
pointers during a same-process re-configuration.
This patch sets the FOLDER target property for the automoc target
to the same value as of the actual target. This organizes the targets
in IDEs with folders better.

From the option documentation of VS >= 7.1:
"In earlier versions of Visual C++, the compiler used several discrete
heaps, and each had a finite limit. Currently, the compiler dynamically
grows the heaps as necessary up to a total heap size limit, and requires
a fixed-size buffer only to construct precompiled headers. Consequently,
the /Zm compiler option is rarely necessary."

Change test if DEL key is allowed from 'curcol > 0' to 'curcol >= 0', as
deleting forward is reasonable in the first column (and probably
expected by users to work).
Support for DEL was first added in commit b3b43508 (BUG: fix for 6462,
delete key should delete the current char, 2008-08-19). The commit
appears to have copied the original logic from the backspace code so the
old 'curcol > 0' logic was accidental rather than intentional.
The performance feature of only performing a git fetch when needed
during the ExternalProject update step is verified during the test.
A fetch is identified by removing the FETCH_HEAD file and checking for
its reincarnation.
This prepares the numberous tests that occur in the ExternalProjectUpdate
test. The tests were passing previously because a fresh build was not performed.
Tests are added for UPDATE_COMMAND to ensure it is working properly. Testing
infrastructure is added along with tests for Git, but tests for other version
control systems could easily be added in the future.
The warnings are enabled for now only when using GCC 4.2 or later.
It may be possible later to also enable them when building CMake
with clang. Don't duplicate the compiler flags if already set.
