convert literal APN name to protocol encoded version before use

The definition of the APN field format in GTPv1 is hidden in a chain
of documents.

3GPP TS 29.060 (the GTPv1-C specification) Section 7.7.30:

> The Access Point Name contains a logical name (see 3GPP TS 23.060 [4]).
> It is coded as in the value part defined in 3GPP TS 24.008

3GPP TS 24.008 Section 10.5.6.1:

> The value part is defined in 3GPP TS 23.003.

3GPP TS 23.003 Section 9.1:

> The APN consists of one or more labels. Each label is coded as a one
> octet length field followed by that number of octets coded as 8 bit
> ASCII characters

This converts a literal APN (e.g. Label1.Label2.Label3) to a structured
field (e.g. \006Label1\006Label2\006Label3)
