Change in osmo-mgw[master]: interpret domain '*' as 'allow any domain'

[Neels Hofmeyr]

Neels Hofmeyr has uploaded this change for review. ( https://gerrit.osmocom.org/10557


Change subject: interpret domain '*' as 'allow any domain'
......................................................................

interpret domain '*' as 'allow any domain'

Make the 'domain NAME' vty doc more descriptive, and add the hint that '*'
means any domain.

In check_domain_name(), exit early in success if the configured domain name is
'*'.

(Do not implement other wildcard functionality for partial matches or the
like, just the single '*'.)
