Subject: Add split_jid/1
X-Git-Tag: 15.09~93
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e3b7d43b76ecbca7c56f2e85c83fa6eaf5de6538;p=ejabberd

Add split_jid/1

This is a convenience reverse of make_jid/1. It allows extracting the jid parts
without relying on using the jid record structure, to abstract details.
