Resolve "bob.math.linsolve parameter documentation in inconsistent order"

Closes #1 (closed)

When accepting this, there are two dependent packages, which need to be modified (basically, the last two parameters need to be exchanged):

• bob.measure:

  • bob::math::linsolve_(XY, seg, one); -> bob::math::linsolve_(XY, one, seg); https://gitlab.idiap.ch/bob/bob.measure/blob/master/bob/measure/cpp/error.cpp#L365

• bob.learn.em:

  • bob::math::linsolve(tacc_Nij_wij2_c, Tt_c, tacc_Fnormij_wij_c); -> bob::math::linsolve(tacc_Nij_wij2_c, tacc_Fnormij_wij_c, Tt_c); https://gitlab.idiap.ch/bob/bob.learn.em/blob/master/bob/learn/em/cpp/IVectorTrainer.cpp#L173

  • bob::math::linsolve(m_tmp_tt, ivector, m_tmp_t1); -> bob::math::linsolve(m_tmp_tt, m_tmp_t1, ivector); https://gitlab.idiap.ch/bob/bob.learn.em/blob/master/bob/learn/em/cpp/IVectorMachine.cpp#L249

This also includes breaking the API of this package and, hence, a new major version.
