Using off_t, at least, in DiskAdaptor layer is problematic because
torrent can contain under 2GiB files but total sum of those files may
exceed 2GiB limit, which makes off_t overflow in 32 bit system without
large file support. So we use int64_t in API. We'll check the file
length before download so that it does not exceed max off_t.
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.

Implemented checksum validation feature(1 checksum for each
file)
The validation takes place after the download.
* src/PieceHashCheckIntegrityEntry.{h, cc}: New class.
* src/IteratableChecksumValidator.{h, cc}: Rewritten.
* src/CheckIntegrityCommand.cc: Changed log message.
* src/Metalink2RequestGroup.cc: Set checksum to
SingleFileDownloadContext.
* src/StreamCheckIntegrityEntry.{h, cc}: Now derived from
PieceHashCheckIntegrity class.
* src/BtCheckIntegrityEntry.{h, cc}: Now derived from
PieceHashCheckIntegrity class.

--allow-overwrite=true is no longer needed to check file
integrity
before download in BitTorrent download.
* src/RequestGroup.cc (getInitialCommand)
Removed RequestGroup from queue when
RequestGroup::getInitialCommand()
throws exception.
* src/RequestGroupMan.cc (getInitialCommands)
Changed CheckIntegrityEntry interface so that it can define
the action when all the chunk checksums are valid.
* src/CheckIntegrityEntry.h
* src/StreamCheckIntegrityEntry.{h, cc}
* src/BtCheckIntegrityEntry.{h, cc}: Currently,when all the
checksums
are valid, then aira2 goes to seeding mode. Sometimes it is
better
to exit rather than doing seeding. So, it would be good to
toggle this
behavior.
* src/CheckIntegrityCommand.cc
* src/AbstractCommand.cc
* src/RequestGroup.cc
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.
