436766a7db Rewrite of the vnet FTP service "send data" code. Instead of creating a buffer
for the whole file, now the buffer has maximum TCP window size and the file is
read on demand. The directory list is now written to a temporary file that can
be sent with the new code.

30264616f4 Added initial support for uploading files to the vnet FTP server. This is
permitted for user "bochs" only, since "anonymous" has read-only access.
TODO: delete / rename file, create / remove directory.

b2b3de60d4 Some more work on the TCP/IP and FTP support.
- TCP: added new method tcpipv4_send_buffer() that can send multiple packets

utility to get rid of code duplication. New class vnet_server_c now contains all
of the network emulation including the DNS code from bxhub.cc.
