tools (common/utils): new methods to parse and generate file size with symbols: - `parseSize` lets parse a size which can be either a int, or a string with a symbol like `Mio` - `getSizeMultiplier` returns a tuple of size with it's multiplier symbol - `getHumanSize` returns a string with size and adapted multiplier.

#!/bin/bash
set -e

usermod -u "$(stat -c %u /var/lib/prosody/.)" prosody

if [[ "$1" != "prosody" ]]; then
    exec prosodyctl "$@"
    exit 0;
fi

if [ "$LOCAL" -a  "$PASSWORD" -a "$DOMAIN" ] ; then
    prosodyctl register "$LOCAL" "$DOMAIN" "$PASSWORD"
fi

exec runuser -u prosody -- "$@"
