check-health: support hard lower limit for voltage

... to detect slow decrease of voltage, for example with UPS.

reintroduce global-wait

shorten modules directory name (global-functions.d -> mod)

bridge-port-to-default -> global-functions.d/bridge-port-to

add global-functions.d/bridge-port-vlan

global-functions.d/inspectvar: add $InspectVar...

to inspect variables. This is useful for variables with (nested) arrays,
for example inspecting $NetwatchNotify (from netwatch-notify):

[admin@Mikrotik] > $InspectVar $NetwatchNotify
-type-> array
  -key-> quad-one
    -type-> array
      -key-> count
        -type-> num
        -value-> 0
      -key-> notified
        -type-> bool
        -value-> false
      -key-> parent
        -type-> nothing
      -key-> resolve-failed
        -type-> nothing
      -key-> since
        -type-> nothing
  -key-> example.com
    -type-> array
      -key-> count
        -type-> num
        -value-> 0
      -key-> notified
        -type-> bool
        -value-> false
      -key-> parent
        -type-> str
        -value-> quad-one
      -key-> resolve-failed
        -type-> nothing
      -key-> since
        -type-> nothing

global-functions: notify about move of $IPCalc and $ScriptRunOnce to …

…modules

Just install with...

$ScriptInstallUpdate global-functions.d/ipcalc

... and/or...

$ScriptInstallUpdate global-functions.d/scriptrunonce

... and use the functions as before.

global-functions*: syntax for ROS 7.x

Strings with escape sequence have to be enclosed in parentheses. Looks
like RouterOS 7.x is stricter here...
