The initial purpose of CSV stats through CLI was to make it easely parsable by scripts. But in some specific cases some error or warning messages strings containing LF were dumped into cells of this CSV. This made some parsing failure on several tools. In addition, if a warning or message contains to successive LF, they will be dumped directly but double LFs tag the end of the response on CLI and the client may consider a truncated response. This patch extends the 'csv_enc_append' and 'csv_enc' functions used to format quoted string content according to RFC with an additionnal parameter to convert multi-lines strings to one line: CRs are skipped, and LFs are replaced with spaces. In addition and optionally, it is also possible to remove resulting trailing spaces. The call of this function to fill strings into stat's CSV output is updated to force this conversion. This patch should be backported on all supported branches (issue was already present in v2.0)
