Normally, the location of the var path should be retrieved from one place,
namely xarCoreGetVarDirPath(). However, this is not used consistently
throughout the core/modules at the moment, and should be cleaned up.

Also, as MrB mentioned, although most sub-directories under var/ are not
supposed to be accessible via web, there are a few cases that do assume
(possible) access, e.g. :
- var/processes/*/graph/ for workflow process graphs,
- var/uploads/ for uploaded files when the uploads module is not used,
- var/calendar/*.ics depending on the evolution of the calendar module

As for where this should be stored, it could be either a module variable,
or (preferably) a configuration variable since it's site-wide.

Specifically for xarCache, this configuration variable should then be
made available through config.caching.php as well (whenever the
xarcachemanager module updates it, or when the value changes),
so that it can be used without core loading too. But this concerns
only the var/cache/config.caching.php file and the location of the
var/cache/output directory - the first needs to be known in advance,
while the second can be defined in config.caching.php.
