We do not want -Dall=ON enabling unsupported options, like
Davix support on Windows, etc.

Fixes: ROOT-9086

The branch name information was not passed correctly to base classes

They were missing a crucial comment header, making the documentation
generation system not pick them up.

this will allow to maintain a standalone version of VMC in parallel, which can be then tagged more frequently according to the needs of the VMC project

the goal was to avoid tutorial names appearing as namespaces.
The change removes from the doc also the tutorials, which is not
acceptable.

ROOT_ADD_TEST cmake macro adds a test executable by invoking
CMAKE_COMMAND -DCMD=... This breaks our FindLibraryName function
which depends on dladdr and the cmake executable confuses it.

This branch is not taken outside of ctest where the code just works.

This was broken before but worked because we scanned all possible
dynamic paths for rdict files which is redundant.

This reverts commit e483e41b.

This reverts commit fc9f3078.

Provide sorting of these entries afterwards - like first show dirs, then
files.

Correctly handle request to same directory - reuse already build list of
items

Eliminate duplictaed model from geom viewer itself

Data model is slightly changed

RBrowser collects all existing items in requested directory. 
Exactly these items are delivered to the client with the reply object,
which just includes pointers on items. Reply object must be transient
and destroyed immediatly after conversion to JSON

RBrowserItem.hxx file will be used in other components, where browser
functionality is required

Once models classed have identical functionality, one could use the only
one.

to prompt a warning whenever something needs to be deprecated
irrespective of the R__SUGGEST_NEW_INTERFACE preprocessor variable
definition.
