qemu-img ftp/http convert

Converting images with ftp or http as source could be done a lot faster. The way it works now (qemu 1.7.50) is significantly slower than the optimal way. 

FTP - how it works now
1. Connect and login to ftp-server. Ask for size of file.
2. Get a chunk of data using rest+retr
3. Goto step 1 again in a loop until all data is retrieved

FTP - better solution
1. Connect and login to ftp-server. Dont ask for size of file.
2. Retrieve all remaining data
3. Goto step 1 again if disconnected/io error (max NN errors etc)


Http - how it works now
1. Connect to webserver and ask for size of file / http HEAD.
2. Get a chunk of data using http Range.
3. Goto step 1 again in a loop until all data is retrieved.

Http - better solution
1. Connect to webserver.
2. Retrieve all remaining data.
3. Goto step 1 again if disconnected/io error (max NN errors).

The QEMU project is currently considering to move its bug tracking to another system. For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or mark it as "Fix Released" if the problem has been solved with a newer version of QEMU already. Thank you and sorry for the inconvenience.


[Expired for QEMU because there has been no activity for 60 days.]
