Previous implementation does not store information which Command cuid
uses which Piece. Mark Piece acquired by SegmentMan by setting
Piece::setUsedBySegment(true).
This option specifies piece selection algorithm used in HTTP/FTP
download. Piece means fixed length segment which is downloaded in
parallel in segmented download. If 'default' is given, aria2 selects
piece so that it reduces the number of establishing connection. This
is reasonable default behaviour because establishing connection is an
expensive operation. If 'inorder' is given, aria2 selects piece which
has minimum index. Index=0 means first of the file. This will be
useful to view movie while downloading it. --enable-http-pipelining
option may be useful to reduce reconnection overhead. Please note
that aria2 honors --min-split-size option, so it will be necessary to
specify a reasonable value to --min-split-size option.
Removed SharedHandle::isNull(). Instead we added operator* and
operator unspecified_bool_type. Removed use of WeakHandle and
replaced with raw pointer.
Added a sets of overloaded functions for
PieceStorage::getMissingPiece() and getMissingFastPiece() to get
multiple pieces more efficiently.

Added --on-bt-download-complete=COMMAND option. For BitTorrent, a
command specified in --on-download-complete is called when
download completes and seeding is over. On the other hand, this
option set the command to be executed when download completes but
before seeding.

Added --min-split-size=SIZE option. aria2 does not split less
than 2*SIZE byte range. For example, let's consider downloading
20MiB file. If SIZE is 10M, aria2 can split file into 2 range
[0-10MiB) and [10MiB-20MiB) and download it using 2 sources(if
--split >= 2, of course). If SIZE is 15M, since 2*15M > 20MiB,
aria2 does not split file and download it using 1 source.

When allocating disk space, for Linux system with fallocate()
system call, first check file system supports fallocate. This
just run fallocate with small chunk and see it succeeds or fails.
If it succeeds, use fallocate() to allocate entire file otherwise
fall back to traditional slower method: writing zeros. This
behavior is enabled in --file-allocation=prealloc, so this is
enabled by default for most modern Linux.

Added --always-resume and --max-resume-failure-tries option. If
--always-resume=false is given, when all given URIs does not
support resume or aria2 encounters N URIs which does not support
resume
(N is the value specified using --max-resume-failure-tries
option), aria2 download file from scratch. The default behavior
is --always-resume=true, which means if all URIs do not support
resume, download fails. I think this is OK because user normally
don't like to see that partially downloaded file is
overwritten(this is particularly true if file size is big). This
option is useful when aria2 is used as download backend and
graceful falling back to overwritten behavior is preferable.
Added exit status value 8, which means download failed because
server did not support resume.

Avoid to calculate end() iterator in each loop. std::deque is
particularly slow. Make sure that recalculate end iterator if
element is erased during loop.

faster one.

Now the constructor of AbstractDiskWriter takes filename as an
argument and filename argument is removed from openFile(),
initAndOpenFile(), openExistingFile() interface. storeDir
member and its accessor functions are removed from DiskAdaptor
because it is not used anymore. size() member function of
DefaultDiskWriter, DirectDiskAdaptor and MultiDiskAdaptor now
can be called without opening file.

BitfieldMan::getMissingIndexes family functions now takes
unsigned char* bitfield instead of stl container for efficiency.
PieceSelector::select now takes this
bitfield. RarestPieceSelector::select now also performs
efficiently for this change. bitfield namespace is introduced
and it has several helper functions to handle basic bitfield
operations such as test, count set bits, etc.

Added 'falloc' parameter for --file-allocation option. 'falloc'
allocation mode uses posix_fallocate() system call to allocate
file on disk. If you are using newer file systems such as ext4
(with extents support), btrfs or xfs, 'falloc' is your best
choice. It allocates large(few GiB) files almost instantly.
Don't use 'falloc' with legacy file systems such as ext3 because
it takes almost same time as 'prealloc' and it blocks aria2
entirely until allocation finishes. 'falloc' may not be
available if your system doesn't have posix_fallocate() system
call.
