[PATCH 1/2] rlCleanupGenFinal: provide non-env variables for the cleanup script
by Jiri Jaburek
Commit fda79f594114c incorrectly assumed that all internal beakerlib
variables are exported to the environment. This caused the cleanup
execution to "work" on the basic level, but things using ie.
$__INTERNAL_JOURNALIST (and many others) were broken.
The solution is to extract even local/global "not exported" variables,
ideally with correct attributes (array, readonly, exported, ..).
Also fix documentation, which is incorrect even prior to this commit.

-Since the cleanup script runs as a separate script, the environment
-IS NOT SHARED, except for BEAKERLIB_DIR, which is exported explicitly upon
-cleanup script generation - that means no other variables are shared between
-the test and the cleanup script, therefore make sure to add only fully expanded
-strings, not variable names.
-
+The cleanup script shares all environment (variables, exported or not, and
+functions) with the test itself - the cleanup append/prepend functions "sample"
+or "snapshot" the environment at the time of their call, IOW any changes to the
+test environment are synchronized to the cleanup script only upon calling
+append/prepend.
+When the append/prepend functions are called within a function which has local
+variables, these will appear as global in the cleanup.
