The only leftovers were the unused compiler.h file and the LICENSE file
which is already mentioned in each and every ebtree file header.
A few build paths were updated in the contrib/ directory not to mention
this directory anymore, and all its occurrences were dropped from the
main makefile. From now on no other include path but include/ will be
needed anymore to build any file.
As part of the include files cleanup, we're going to kill the ebtree
directory. For this we need to host its C files in a different location
and src/ is the right one.
glibc-2.11 on x86_64 provides a machine-specific memchr() which is faster
than the generic C implementation by around 40%, so let's make it possible
to use it instead of the hand-coded version.
This version implements both 32 and 64 bit versions at once, it
avoids the need to have two separate output files. It also improves
efficiency on i386 platforms by adding a little bit of assembly where
gcc isn't efficient.
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.
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.
