due the fact that KF5 uses the flag "QT_NO_CAST_FROM_ASCII" we can't cast directly a string, but instead we must use QLatin1String
even the flag "QT_NO_URL_CAST_FROM_STRING" is set, we can't cast a QString to QUrl directly, but instead use the setUrl function
Modified only the _global.h header, is the one used by external applications (like discover)

signals: -> Q_SIGNALS:

- fromAscii -> fromLatin1
- toAscii -> toLatin1
- qInstallMsgHandler -> qInstallMessageHandler
- QWeakPointer -> QPointer
- <funcitonname>.moc -> mov_<functionname>.cpp

the targetRemovals list contains the removed packages in the current operation.
When we are processing the replacement operation, the replaced packages are inserted in the targetRemovals List.
Later, after verifing that the pkg filesystemAdditions does not conflict with the files in the system, the pkg is validated. If the pkg analized in the current loop must be removed we must skip the package conflict and the database conflict because we want really to remove it, not verify if conflicts with an installed one.

add only the replacement pkg
remove the replaced pkg with its "provided" pkgs

use modern way to check if doc target already exist

Make tests compile again, add two new testcases to versiontests and fix the one version reported by Luca which didn't work...
Basically this adds support for chars inside version strings

Add progress reporting for akabei-create-db add during the check if targets may be in database already
