84a3b0ef87 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.

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=47461

0f9f179bec 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.

c2ac57f6c9 subparse: don't try to index string with -1
If the len of the string turns out to be 0, str[len - 1] resolved to
str[-1] which is not a good idea.

Make sure we did initial negotiation and segment pushing if we get GAP events
before buffers.
