by casting dec_value to unsigned (uintmax_t)

On i686 the long is 4 bytes and when converted to uint64_t some big
unsigned values get converted to very big negative values

See https://github.com/vlm/asn1c/issues/185#issuecomment-372546490

On i686 the long is 4 bytes and the right shift with more then 32 bits
is probably an undefined behaviour

Instead in two bytes the ENB-UE-S1AP-ID was encoded in three
For value 2 the correct encoding is `02 00 02 00`
and not `03 00 02 00 00`

And the MME-UE-S1AP-ID were encoded in 5 instead of 4

Files are from #185 and were renamed to match the Makefile's glob
pattern

bin/1.bin -> nextepc/sample-S1AP-PDU-1.aper

Thanks to @acetcom

Previously when decoding fails the memory was reset with memset after
casting the specifics to asn_CHOICE_specifics_t in order to get the size

The problem is that the OPEN TYPE could contains a different type not
derived from asn_CHOICE that does not have a struct_size member with a
valid size.

This fixes test failures in examples/sample.source.S1AP

This makes debugging and testing a lot more easier as skeleton files are
not copied and you don't need to execute `make regen` after every change
in the skeleton files.

You need to manually remove all skeleton files and run
`make regen-makefile` the first time after checking out this commit

Rename the existing files to match the glob used in the Makefile

To execute the tests run `make check` or `make check-aper`

and regenerate the the S1AP Makefile

According to Rec. ITU-T X.691 (08/2015)

11.5.3 Let "range" be defined as the integer value ("ub" – "lb" + 1), and let the value to be encoded be "n".

When generating code for multiple ASN.1 syntaxes that have clashing
names, we need to add a prefix in order to prevent clashes in the global
C symbol namespace.  Using the ASN1C_PREFIX environment variable and
this patch serves as a work-around to that.  All non-basic type names
as well as references to that type and source code + header file names
will be pre-fixed accordingly.

This is a re-implementation of this feature due to osmocom's
implementation version can not work on newest asn1c repository.
