I noticed this when debugging some grenade issues failures. An include of grenade/functions stores the current value of XTRACE (on) and disables xtrace for the rest of the import. We then include devstack's "functions" library, which now overwrites the stored value of XTRACE the current state; i.e. disabled. When it finishes it restores the prior state (disabled), and then grenade restores the same value of XTRACE (disabled). The result is that xtrace is incorrectly disabled until the next time it just happens to be turned on. The solution is to name-space the store of the current-value of xtrace so when we finish sourcing a file, we always restore the tracing value to what it was when we entered. Some files had already discovered this. In general there is inconsistency around the setting of the variable, and a lot of obvious copy-paste. This brings consistency across all files by using _XTRACE_* prefixes for the sotre/restore of tracing values. Change-Id: Iba7739eada5711d9c269cb4127fa712e9f961695
