names:
  URIs == raw filename (no encoding), all escaped
  We generate display absolute paths as filenames if possible, otherwise
  as IRIs. This means we can display nice URIs for native utf8 backends
  and filenames. However, URIs for non-utf8 shares will look bad. If we know
  the encoding we can still get nice non-absolut display names though.
  
  In client we store names as mountpoint + non-escaped no-encoding string.
  Non-uri display name handling done in daemon
  
GStatable iface for fstat() support
GSaveStream, with get_final_file_info()

open for writing:

append vs truncate
fail on existing or replace

mtime match
mtime return
backup (suffix+prefix)
create filename from display name
unique name
keep inode or be atomic?

filename_for_display_name()
write_append() /* optional (not on webdav) */
write_new()
write_replace()




ftp supports:
 overwrite
 append
 generate unique name
 
http+webdav supports:
  overwrite
  append in recent versions
  get mtime, length, mimetype, atime on read open
  




async thread work:

function to run in thread
data to pass to thread
cancel identifier
pass in cancel func + data
way for function to communicate with mainloop (of specific context)
does mainloop notifiers block on ack?
