ClassImp is a macro defined in Rtypes.h. It can be written without trailing
semicolon. However, clang-format is based on lexing and it doesn't know at
all about preprocessors and how to expand macros. When visiting ClassImp(X)
it thinks this is not a completed entity (as it doesn't expand macros) and
considers the next line as continuation of the previous.

Inserting a semicolon fixes the issue and makes formatting with clang-format
in the ROOT codebase less tricky.

Add name as data member of the GSL root solver for multi-dim case. This fix a bug in the Name() method

Introduced in 474c4653.

This allows the use of TCollection::Delete

Leverage that the bit set by the TObject destructor might still be there when the list clears or delete

Disable analyzer alpha checks yielding a few false positives. Enable all other
stable static analysis checks by default.

Add experimental clang-tidy modernization checks.

To preserve the connection (without introducing one when there was none),
between the content of container that is being cleared or deleted and the
list of Cleanups, we re-use fCache to inform RecursiveRemove of the
node currently being cleared/deleted.

This replaces:

‘Fix ROOT-5284 which was due to a unusual setup (in TParallelCoord) leading to only partial cleanup.’

and the related commit:

‘Fix thread-safety problems with cleanup of containers’
d0b6642c

This is done by avoiding to 'Draw' those and simply Paint them as a
side effect of the TParrallelCoord's painting.

This insures that the already-written basket are not included.

Once per Snapshot call, each thread creates a TBufferMergerFile.
Once per TBB task (lifetime of an input TChain) each thread creates
a new output TTree, assigns branches to it and adds it as a clone
to the input TChain.
