deprecating gnutls_transport_set_lowat()

[Lucas De Marchi]

I'm a contributor of ConnMan project and we use gnutls. Recently
gnutls deprecated the function gnutls_transport_set_lowat() and it
seems there's no active developer in ConnMan to know what we have to
do. Should we just remove that call or do we have to do something
else?

The code I'm talking about is this one:
http://git.kernel.org/?p=network/connman/connman.git;a=blob;f=gweb/giognutls.c;h=6856a2abbaf2d63c1bbebc6ff4367a9d98cab8eb;hb=HEAD

I appreciate if you could give a look in this file.


Thanks
