samiparse: clean up some GString usage
...
There's no need to re-assign the return value of
g_string_append_*() functions and such to the variable
holding the GString. These return values are just for
convenience so function calls can be chained. The actual
GString pointer won't change, it's not a GList after all.

samiparse: micro-optimise entity handling
...
Avoid relocations and hard-code entity string length
in the struct, since we basically get it for free here.

samiparse: fix handling of self-closing tags
...
We would check the wrong string (rest of line rather than element)
for the / suffix of self-closing tags, which is not only wrong but
also has atrocious performance with certain strings like the garbled
nonsense clusterfuzz feeds us, which might cause discoverer to time
out when processing garbled SAMI files.

subparse: don't deref a potentially NULL variable
...
If the html SAMI data is malformed, then retrieving the attribute name
may fail. We then cannot retrieve the attribute value.
