Vast amount of changes in order to adapt the project to Julia v1.4.

Some features of the old project could not be recovered (so far)
in the adapted project, in particular those which involve user-level C
call-back functions called within the kernel of PETSc and to be
implemented in Julia (e.g., MatShell or TS solvers).
