In aria2, one piece is downloaded from several peers, so when hash
check failed for that piece, it cannot determine which peer(s) sent
bad data. So, we ignore peer who sent last block of data in random
minutes. We use randomized timeout because all peers get waken up at
the almost same time.
Removed SharedHandle::isNull(). Instead we added operator* and
operator unspecified_bool_type. Removed use of WeakHandle and
replaced with raw pointer.
Don't inject validator into BtMessage in metadataGetMode because
most of the checks depends on the total length of download but it
is unknown. Delegate metadataGetMode to BtMessage.
* src/DefaultBtMessageFactory.cc
* src/DefaultBtMessageFactory.h
Rewritten Exception class. Throw exception object, not its pointer and
catch by reference, so that remove problematic delete operator for
catched exception.
* src/Exception.cc
* src/Exception.h
* test/ExceptionTest.cc
* src/*: All files throwing/catching exception.
* test/*: All files throwing/catching exception.
Rewritten SharedHandle. Now copy constructor taking raw pointer
has
keyword explicit and SharedHandle's default constructor
initializes
its internal obj to null, old implementation initializes it
using
obj's default constructor.
To assign null, write SharedHandle<T> x(...); x.reset();
TODO: test/SharedHandleTest.cc needs more tests.
* src/SharedHandle.h
Bootstrap through node added by port message.
Currently bootstrap is executed if the number of buckets in routing
table is 1.

* test/MockDHTTask.h
Added DHT functionality, compatible with mainline.
DHT is disabled by default. To enable it, give --enable-dht to
aria2c.
You may need to specify entry point to DHT network using
--dht-entry-point. DHT uses UDP port to listen incoming message.
Use --dht-listen-port to specify port number. Make sure that
your
firewall configuration can pass through UDP traffic to the port.
The routing table is saved in $HOME/.aria2/dht.dat.
