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.

Fixed the bug that causes segmentaion fault when resuming
download
using metalink without size tag. Reproducible only using HTTP
URI.

* src/FtpNegotiationCommand.cc
Fixed broken gzip inflation.
Turn off segmented downloading if gzip content is smaller than
or equal
to 1MiB and inflate the data on the fly, because HTTP response
header
doesn't contain the length of inflated file we can't determin
where
the chunk of data should be written.
On the other hand, if gzip content is larger than 1MB, then turn
off
on the fly inflation, because some servers returns
"content-type: gzip"
for *.tgz, *.gz files.

Now SegmentMan::findSlowerSegmentEntry() picks up the segment
for which
the transfer has not yet started.
Rewritten SegmentMan::registerPeerStat() and
SegmentMan::getPeerStat().

Cache last calculated average download/upload speed.
PeerStat::getAvgDownloadSpeed(), PeerStat::getAvgUploadSpeed()
return
cached value.
Now SpeedCalc::changeSw() is called from
SpeedCalc::calculateSpeed()

Use File::exists() instead of File::isFile() to allow
non-regular file
such as block spacial device.

Added the ability to save signature when download is completed
if
signature is available. The filename of signature file is the
path to
download file followed by ".sig". If it already exists, then
signature
will not be saved.

Renamed --bt-seed option as --bt-seed-unverified so that it
makes clear
that this is not going to verify files using piece hashes.

Moved the calls of std::ios::exceptions() inside of try-catch
block
because if an error occurred in constructor of std::fstream,
then
exception is thrown immediately when std::ios::exceptions() is
called
which results unhandled exception and aria2c aborts.
* src/DefaultBtProgressInfoFile.cc
Fixed the bug that causes infinite loop when the number of
pieces are
fewer than allowed fast set size which is 10 by default.
