HTTP transfer
-------------
* stream POST to GET in real time, whithout storing the file
* handle acl
* get base URL from ejabberd_http config
* add parameters:
- store directory
- URL of upload
* virtual host handling
* check security stuffs:
- limit file size at upload time
- acl
* transfer socks5 -> HTTP
* transfer HTTP -> socks5
