/*! IPA Name: Arbitrary length blob, not necessarily zero-terminated.
* In osmo-hlr, struct hlr_subscriber is mostly used as static reference and cannot serve as talloc context, which is
* why this is also implemented as a fixed-maximum-size buffer instead of a talloc'd arbitrary sized buffer.
* NOTE: The length of val may be extended in the future if it becomes necessary.
* At the time of writing, this holds IPA unit name strings of very limited length.
