ok.

gst_structure_to_string add ';' to the end
gst_caps_to_string do not add ';' to the end of each field anymore

ideally the gst_structure_to_string_add should use '(' and ')' to delimiter the
structure because the 'open' and 'close' delimiters would be in just one place.
currently, the function that calls gst_structure_to_string is in charge of
write the open delimiter which is "(structure)".
so, gst_structure_from_string does NOT look for "(structure)" open delimeiter,
but looks for the structure name, followed by fields and them followed by ';'
(currently it could find \0 at the end)

a nested gst_structure looks like this:

"Exif, Camera=(structure)Camera, XResolution=(int)72, YResolution=(int)73;,
Image Data=(structure)Image-Data, Orientation=(string)top-left;;"

*notice the difference beteween the fisrt and second "Image Data" !=
"Image-Data"
the fisrt is the name of the structure field of Exif structure
the second is the name of the structure Image-Data (which can not have ' ' in
it)
