6491270b3a large IPv6 redesign of peer ping methods!
removed preferred IPv4 in start options and added a new field IP6 in
peer seeds which will contain one or more IPv6 addresses. Now every peer
has one or more IP addresses assigned, even several IPv6 addresses are
possible. The peer-ping process must check all given and possible IP
addresses for a backping and return the one IP which was successful when
pinging the peer. The ping-ing peer must be able to recognize which of
the given IPs are available for outside access of the peer and store
this accordingly. If only one IPv6 address is available and no IPv4,
then the IPv6 is stored in the old IP field of the seed DNA.
Many methods in Seed.java are now marked as @deprecated because they had
been used for a single IP only. There is still a large construction site
left in YaCy now where all these deprecated methods must be replaced
with new method calls. The 'extra'-IPs, used by cluster assignment had
been removed since that can be replaced with IPv6 usage in p2p clusters.
All clusters must now use IPv6 if they want an intranet-routing.

ad35d9294f added a 'stats' table which records some peer statistics twice every
hour. The table can be shown with
http://localhost:8090/Tables_p.html?table=stats

The entries have the following meaning: 
aM: activeLastMonth
aW: activeLastWeek
aD: activeLastDay
aH: activeLastHour
cC: countConnected (Active Senior)
cD: countDisconnected (Passive Senior)
cP: countPotential (Junior)
cR: count of the RWI entries
cI: size of the index (number of documents)

The entry keys are abbreviated to reduce the space in the table as the
name is written again for every row.

This is the beginning of a 'yacystats' micro-alternative als built-in
function in YaCy. Graphics may follow after some time if enough test
data is available.

e31b0e6d67 - update javadoc Seed.getIP
- default mySeed.ip to hostip in SeedDB.initMySeed() if Intranetmode
this allows to become senior status in intranet hosted search network with view peers,
otherwise peer would stay junior because of default init with loopback ip as public (dna) ip.

022c6d3ce1 do YaCy p2p connections using a timeout-request which covers the http
request into a separate thread and ignores the furthure result of a
request if that does not answer within the requested time-out. This is a
try to solve a problem with the peer-ping, which hangs whenever a peer
appears to be dead or blocked.

f8ce7040ab remote search peer selection schema change:
- all non-dht targets (previously separated into 'robinson' for dht-like
queries and 'node' for solr queries) are non 'extra' peers, which are
queries using solr
- these extra-peers are now selected using a ranking on last-seen,
peer-tag-matches, node-peer flags, peer age, and link count. The ranking
is done using a weight and a random factor.
- the number of extra peers is 50% of the dht peers
- the dht peers now exclude too young peers to prevent bad results
during strong growth of the network
- the number of dht peers (and therefore extra-peers) is reduced when
the memory of the peer is low and/or some documents still appear in the
indexing-queue. This shall prevent a peer from deadlocks when p2p
queries are made in a fast sequence on weak hardware.

6932aa4d7a use configured admin-username for api calls
- the admin user name can be configured, in apiExec calls the default "admin" username is used. 

TODO: the bin/apicall.sh script should likely take that into account.

5e31bad711 - the webgraph shall store all links which appear on a web page and not
all unique links! This made it necessary, that a large portion of the
parser and link processing classes must be adopted to carry a different
type of link collection which carry a property attribute which are
attached to web anchors.
- introduction of a new URL class, AnchorURL
- the other url classes, DigestURI and MultiProtocolURI had been renamed
and refactored to fit into a new document package schema, document.id
- cleanup of net.yacy.cora.document package and refactoring

765943a4b7 Redesign of crawler identification and robots steering. A non-p2p user
in intranets and the internet can now choose to appear as Googlebot.
This is an essential necessity to be able to compete in the field of
commercial search appliances, since most web pages are these days
optimized only for Google and no other search platform any more. All
commercial search engine providers have a built-in fake-Google User
Agent to be able to get the same search index as Google can do. Without
the resistance against obeying to robots.txt in this case, no
competition is possible any more. YaCy will always obey the robots.txt
when it is used for crawling the web in a peer-to-peer network, but to
establish a Search Appliance (like a Google Search Appliance, GSA) it is
necessary to be able to behave exactly like a Google crawler.
With this change, you will be able to switch the user agent when portal
or intranet mode is selected on per-crawl-start basis. Every crawl start
can have a different user agent.

5878c1d599 - refactoring of log to ConcurrentLog:
jdk-based logger tend to block
at java.util.logging.Logger.log(Logger.java:476) in concurrent
environments. This makes logging a main performance issue. To overcome
this problem, this is a add-on to jdk logging to put log entries on a
concurrent message queue and log the messages one by one using a
separate process.
- FTPClient uses the concurrent logging instead of the log4j logger

72adbeae90 !Important: move from Hashtable to HashMap
Hashtable is an obsolete collection v1, now since v2 offers HashMap with same or better
functionality. Please review, almost all code was already moved, so only a few changes. That is not the issue,
but I found notices that some (ugly big) helper classes had to be created in past
to compensate missing Hashtable's functionality. I'd like input if we can remove some of them.
look for //FIX: if these commits
