As these are exported variables by convention they should be uppercase.
Travis/Spellcheck fails because they are not uppercase and it therefore
expects them to be defined or set before use.
Sometimes FreeDNS does not reurn the subdomain page but rather
returns a page regarding becoming a premium member. This usually
happens after a period of inactivity. Immediately trying again
returns the correct subdomain page. So, we will try twice to
load the page
Now the FREEDNS_USER and FREEDNS_PASSWORD need only be exported the first
time it is used and whenever the userid or password is changed. Subsequent
runs use the cookie cached in account.conf

message:
SC2034: $VARNAME appears unused. Verify it or export it.
most of these are related to the style:
we generate global vars, which are used in other functions.
the var "lexical_url" was really unused (left it as comment)
the travis-check now does not need anymore special flags.

"Don't use [] around ranges in tr, it replaces literal square brackets."
this introduces another warning:
"Use '[:lower:]' to support accents and foreign alphabets."
This is more a style thingy because we really want to only catch A-Z.
work around this by using a shellcheck-directive and a comment
that the [:lower:] will not work with e.g. busybox-ash.
if we later really want to use [:lower:], we should use 'sed' for that.
