Previously only the last line of the match was being saved, not all
lines involved in matching.
Log lines are now broken into 3 part tuple, with the line pre-datetime,
the datetime, and post-datetime. Allows reformation of full line, but
also use of the line without the datetime present.
Attempting to use the term "tupleLine(s)" where possible, to avoid
confusion with normal read lines.
May also wish to consider that regexs could be made to capture more
lines of interest if some form of unique reference is available. This
may allow more lines of interest to be captured, which may not be picked
up by the traditional "grep <ip>" approach i.e. ones which do not have
the ip address in.
This also simplified the fail2ban-regex statistics for missed lines.
Also resolved bug with missed lines time extracted for debuggex having
some lines present which were captured in a multiline regex.
Also resolved independent issue with ignored line check including the
datetime, which raised assertion error in the rare case the datetime
matched the ignore regex, and the rest of line only matched a failregex

ChangeLog
bin/fail2ban-regex
fail2ban-testcases
fail2ban/server/filter.py
This issue was caused by the fact that every "line" is processed for each
regex, meaning each line was duplicated for every regex. This caused
duplicate fail matches and the buffer filling too quickly and possibly
missing failures.
