[Spice-devel] [PATCH v4 2/8] vdagent: move file xfer initialization to a function

[Frediano Ziglio]

From: Victor Toso <me at victortoso.com>

This patch creates two functions:
- xfer_get_download_directory()
- vdagent_init_file_xfer()

The logic should be similar as it was before this patch, taking in
consideration the global variables fx_open_dir and fx_dir which are
set from command line.
