This option enables disk cache. If SIZE is 0, the disk cache is
disabled. This feature caches the downloaded data in memory, which
grows to at most SIZE bytes. The cache storage is created for aria2
instance and shared by all downloads. The one advantage of the disk
cache is reduce the disk seek time because the data is written in
larger unit and it is reordered by the offset of the file. If the
underlying file is heavily fragmented it is not the case.
Previous implementation does not store information which Command cuid
uses which Piece. Mark Piece acquired by SegmentMan by setting
Piece::setUsedBySegment(true).
Added a sets of overloaded functions for
PieceStorage::getMissingPiece() and getMissingFastPiece() to get
multiple pieces more efficiently.

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.

Added option --bt-prioritize-piece. This option instruct aria2 to
try to download first and last pieces of each file first. The
argument can contain 2 keywords:head and tail. To include both
keywords, they must be separated by comma. These keywords can take
one parameter, SIZE. For example , if head=SIZE is specified,
pieces in the range of first SIZE bytes of each file get higher
priority. tail=SIZE means the range of last SIZE bytes of each
file. SIZE can include K or M(1K = 1024, 1M = 1024K).

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.

Use LongestSequencePieceSelector for HTTP/FTP/BitTorrent
integrated downloads. This PieceSelector subclass finds the
longest continuous sequence in the available missing pieces and
selects the last index of such sequence. This makes HTTP/FTP
connections less interrupted by the pieces obtained by
BitTorrent peers.

Preallocate non-requested file which is adjacent forward to
requested

files like FAT32 while downloading.

Lower CPU load when --max-download-limit is used.
There is up and down in speed indicator when enabling
http-pipelining but a download goes well. I think the problem is
that
because http-pipelining is enabled, DownloadCommand is created
for
each segment and in its constructor, PeerStat::downloadStart()
is
called. In PeerStat::downloadStart(), speed calculation object
is
reseted, which makes download speed zero.
* src/DownloadCommand.cc
Rewritten using accumulate.

Code clearnup.
* src/FtpNegotiationCommand.cc
* src/HttpResponseCommand.cc
* src/Piece.{h, cc}: Added SubPiece infrastructure to track down
the data smaller than block length.
A block length can be specified by constructor's argument.
* src/DefaultPieceStorage.{h, cc} (getMissingPiece):
Get a missing piece in the range of given FileEntry. This
function is
not used in the program yet.
* src/Util.h: Added some macros.
