Fix rootext shared library Makefiles

See merge request !11

The only C++14 dependency was std::make_unique. This adds a compatibility
layer to provide a make_unique implementation when compiling against
C++11.

The macro ClassDefOverride uses the C++11 override keyword instead of
virtual. This eliminates some compiler warnings about mixed usage of
virtual and override.

This also converts some loops to range-based loops.

Evaluating a fitter does not change its internal state.

Explicit new/deletes are ugly. As a further benefit, using make_unique
makes the allocation exception-safe.

This makes sure, all class constructors initialize every member variable.
Overriding implementations of member functions in derived classes are
marked override instead of virtual.

Marking single argument constructors explicit avoids unintentional object
creation through implicit conversion.

STL algorithms usually perform better than handwritten code and make
the code more readable.

fLevel is unsigned and cannot be smaller than zero.

Calling virtual functions in con-/destructors is dangerous. This
replaces virtual calls with non-virtual calls where necessary.

C-style casts are error prone and hard to find. This removes
all unnecessary casts and replaces the remaining C-style
casts with C++-style casts.

The code has become quite unreadable over time. This fixes all
code to be in the same indentation format and also wraps long
lines to fit within 80 characters.

The current Makefiles (1) do not follow the naming
convention used by implicit GNU make rules, e.g. the
CPP variable name is supposed to be the C pre-processor
not the C++ compiler and (2) most of the content is
repeated boilerplate to compile a shared library that
integrates well with CERN ROOT.

This commit implicit GNU make rules where possible and
also changes dependency generation to be actually useful.
Additionally all whitespace errors detected by git (spaces
before tabs and trailing whitespaces) are fixed.
