Subject: - enable all traces and debugs by default to not hurt anyone who not aware of this... 
X-Git-Tag: v1_7_100~211
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=197a4d5c6353bc4a672c7d48953a1bbb3b9723b2

- enable all traces and debugs by default to not hurt anyone who not aware of this and allow customers gather all logs by default;
- added compile warning for case CDEBUG is disabled;
- fixes in configure keys, using AC_ARG_ENABLE(feature) implies that bash variable names is $enable_feature.
