master: fix limits computation for ABSOLUTE

As bobkare reported on IRC:

    ... limits for ABSOLUTE fields are matched against raw input
values rather than value/$poll_interval like other time-based
counters?

This commit does fix the issue. Limits do now behave like their
COUNTER & DERIVE counterparts.
* master:
  - fix limit for ABSOLUTE checks too. Cherry-picked 334b691 as 1e44056.
p/df: also ignore devtmpfs

devtmpfs should be excluded by default also.

I explicitly don't exclude tmpfs as it is quite useful as metric.

Closes: D:710899
plugins/df: ignore devtmpfs. Cherry picked from 2.0.16-2. (Closes: #710527)
asyncd: use the same rules as munin-update

munin-update does some squashing on invalid chars when using non-multigraph
plugins. This is done transparently when using the plain old TCP transport.

As munin-async(d) uses the spoolfetch transport that is multigraph-based, it
has the side effect not squashing the root plugin name. This patch squashes the
root plugin name in the same manner as done by munin-update.

It therefore enables to insert the munin-async(d) couple in-place to benefit
transparently.

Closes D:710529
* asyncd: use the same rules as munin-update. Cherry-picked d4ba06b as 87975d0. (Closes: #710529)
master: adding ":" to the allowed chars in CGI

":" is a valid char for an IPv6-enabled "ip_" plugin
add ":" to the allowed chars in CGI. Cherry-picked 456e117 as 7d3cb5f. (Closes: #710527)
Fix for munin-cgi-graph crash in trend and predict.

 - use get_field_name on the fieldnames for trend and predict.  A too long
   internal field name would make munin-(cgi-)graph crash.

 - bonus fix: use the label, and not the internal name, for the predict and
   trend labels.  (df graph will use "/home predict" instead of "_dev_vg0_home
   predict", or similar)
fixes for munin-cgi-graph crashes in trend and predict. Cherry-picked f325fd6 as 5cb74ba.
