Later on LisLinearSolver can be completly removed
since it was only used from
EigenLisLinearSolver that is still available.

The definition of implicit copy assignment operator for a class
is deprecated because it has a user-declared copy constructor
as issued by -Wdeprecated-copy warning.

Since the definitions of default copy constructors are implictly
created by the compiler (as well as the copy assignments)
the definitions are not needed.

Update and unify documentation.

This covers both, the serial and parallel cases: seqaij and mpiaij.
The latter matrix type will not work for serial cases---#3203.

From the documentation https://petsc.org/release/docs/manualpages/Vec/VecSetUp.html:
"For basic use of the Vec classes the user need not explicitly call VecSetUp(), since these actions will happen automatically."

The matrix type set through command line arguments was
overriden by an extra call. Changing the orders assigns
the command line options higher priority than the default
aij matrix type.

The Sparse' module parts are used also if unsupported
module support is turned off.
