In order to optimize the generated code, we will need data structures
that can be traversed in several passes before the actual code is
generated.
Refactor the code so that if first builds (essentially) a list of
funs that do the actual code generation, and a second function
that will call the funs one at the time.

A long term goal is to eleminate the asn1ct_gen_per_rt2ct module
in favor of the asn1ct_gen_per module, so will have
asn1ct_gen_per_rt2ct call asn1ct_gen_per.

Currently, the generated code suppresses warnings for unusued variables
by assigning to the "_Val" variable, for example:
_Val = Tmpval5
To be completely safe, that should have been:
_ = Tmpval5
in case there happens to more than one such assignment in the same
scope.
However, a better way to suppress warnings is to simply use the
'nowarn_unused_vars' compiler option. That method will also work
for more complicated expressions there it would be cumbersome to
suppress warnings by assignment to "_".

It is time to clean up the mess of back-ends.
Remove all the obsolete back-ends and simplify the options used
to select them.
New Option Old Equivalent
---------- --------------
ber ber_bin,optimize,nif
per per,optimize,nif
uper uper_bin
The old options will still be recognized and translated to the
new options, but will also print a warning.
That implies that deprecated features that only are implemented
in the old 'ber' back-end will no longer work (e.g. the
{Typename,Value} notation).
Also make the return type for the generated encode/2 function
consistent. It used to be a binary for per and uper, and an iolist
for ber. Always make it a binary.

Of the back-ends that we are going to keep, only the UPER back-end
support the obsolete {Typename,Value} notation. For consistency
with the PER and BER encodings, remove the support for UPER
encoding too. Also remove vestiges of the support for the
notation in the other back-ends.

Instead of looping over the list of which options contain defaults, one case statement is generated for each optional attribute.
