The timer parser looks for the next slash after the last timer, which is
very far away. Those 4 occurrences have been fixed to match the way it's
done in URL sorting, which is faster. Average speed gain is 5-6% on -srv
and -pct.

Using -u{,c,e,t,a,to,ao} it is possible to get per-URL statistics, sorted by
URL, request count, error count, total time, avg time, total time on OK requests,
avg time on OK requests.
Since it has to parse URLs and store a number of fields, it's quite slower
than other methods, but still correct for production usage (typically 800000
lines or 270 MB per second on a 2 GHz system).
Results are sorted in reverse order so that it's easy to catch them by piping
the output to the "head" command.

It's sometimes very useful to be able to monitor a production status in real
time by comparing servers behaviours. Now halog is able to do this when called
with "-srv". It reports various fields for each server found in a log, including
statuses, total reqs, valid reqs, percent of valid reqs, average connection time,
average response time.
A new idea came up to detect the presence of a null byte in a word.
It saves several operations compared to the previous one, and eliminates
the jumps (about 6 instructions which can run 2-by-2 in parallel).
This sole optimisation improved the line count speed by about 30%.
All files referencing the previous ebtree code were changed to point
to the new one in the ebtree directory. A makefile variable (EBTREE_DIR)
is also available to use files from another directory.
The ability to build the libebtree library temporarily remains disabled
because it can have an impact on some existing toolchains and does not
appear worth it in the medium term if we add support for multi-criteria
stickiness for instance.
