Implemented download speed based URI selection algorithm.
Introduced new option --uri-selector.
If --uri-selector=feedback is given, aria2 uses download speed
observed
in the previous downloads and chooses fastest server in the URI
list.
Currently at most 10 URIs are considered to introduce
randomeness for
finding better servers. The speed is average download speed in
the
downloads.
On the other hand, if --uri-selector=inorder is given, which is
default,
URI is tried in order in URI list.
The usage text for the new option has not been written yet.

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.

Added 'mem' option value for --follow-metalink,
--follow-torrent.
If it is give, metalink/torrent file is not written to the disk,
but
just is kept in memory. Parsing is occurred on memory.

Implemented BitTorrent/http/ftp integrated download.
I've rewritten lots of files and now some headers have forward
class declarations to reduce compile time.
The implementation is extremely alpha stage, I recommend to use this
for testing purpose only.
RequestGroup::getNextCommand() was renamed to
createNextCommand().
Added its overloaded method.
* src/RequestGroup.h
(_numConcurrentCommand): New variable.
(setNumConcurrentCommand): New function.
* src/RequestGroup.cc
Abort download if same file is being downloaded concurrently.

* src/HttpResponseCommand.cc (executeInternal)
* src/FtpNegotiateCommand.cc (recvSize)
* src/message.h (EX_DUPLICATE_FILE_DOWNLOAD): New definition.
* main.cc: Added help message for -i option.
