Add new 'qlicenseservice' static library, which now contains most
of the code shared between the different tool executables, and link
the the tools against it. After this the sub-project for the main
'qtlicd' binary contains only the platform specific daemon sources.

This makes the code more testable, as auto-tests to-be-added in the
future only need to link against the 'qlicenseservice' library in
most cases, without recompiling the sources of referenced symbols.
Same should also help with the included tools that have previously
shared common code.

Move the source files so that all sources for standalone binaries are
located in 'src/<toolname>' directories and for libraries in
'src/libs/<libname>'. Also some minor shuffling of other project
files around - the built binaries and libraries will now be outputted
to 'bin' and 'lib' subdirs, the distributed config and service files
in 'dist' directory.
