Dear Xinpeng,

When obexd receives a file, it parses the filename and other parameters
when processing the packet for the first time, store filename in
obex_session and emit the dbus signal, The signal will be pending first.
then when this file is received, transfer_complete reset obex_session
is called.
When using a computer with Windows 10 installed to send a file to bluez,
obexd will read the data through read_stream; if it is a small file, the
data processed for the first time is marked as final, and transfer_complete
reset obex_session will be called when the data is processed for the first
time. At this point, the dbus signal is still pending, and the dbus method
that requests the file path has not been processed. This will cause the upper
application to not be able to transfer files from the cache directory to the
directory specified by the user.
To solve this problem, emit Filename's dbus signal and force it when
status=active.
Ways to reproduce the problem:
1. Use the computer with windows 10 installed to send a small file to the
computer with ubuntu installed;
2. file size < 10k;
3. After sending, in most cases, the file is located in the ~/.cache/obexd/
directory. Normally, the file should be located in the ~/Download directory.
To fix this, after applying this commit, it also needs to be modified by
the upper-level application. Modified to read Filename from dbus signal if
there is Filename in dbus signal. Otherwise, use the dbus method to request
Filename.

Awesome. Thank you.
