Rationale

Trying to solve a problem with a nodal constraint on a displaced mesh results in a segfault.

Description

This input file reproduces the problem:

[Mesh]
  file = 2-lines.e
  displacements = 'disp_x'
[]

[AuxVariables]
  [./disp_x]
  [../]
[]

[AuxKernels]
  [./disp_x_ak]
    type = ConstantAux
    variable = disp_x
    value = 1
  [../]
[]

[Variables]
  [./u]
  [../]
[]

[Kernels]
  [./diff]
    type = Diffusion
    variable = u
  [../]
[]

[BCs]
  [./left]
    type = DirichletBC
    variable = u
    boundary = 1
    value = 1
  [../]

  [./right]
    type = DirichletBC
    variable = u
    boundary = 4
    value = 3
  [../]
[]

[Constraints]
  [./c1]
    type = EqualValueNodalConstraint
    variable = u
    master = 0
    slave = 4
    penalty = 100000
    use_displaced_mesh = true
  [../]
[]

[Executioner]
  type = Steady

  solve_type = 'PJFNK'
[]

[Outputs]
  exodus = true
[]

Impact

Unable to solve problems with nodal constraints on displaced meshes.

test file

Update buildSideList() calls to use non-deprecated version.

Remove original elem_list, side_list, id_list data structures.  We are
also able to get rid of _n_elems, since only one line of code was
using it and it's now gone.

Refs idaholab#11565.
