The issue is caused by an integer overflow when the `long` passed as
XML_OPTION_SKIP_TAGSTART is assigned to `xml_parser::toffset` which is
declared as `int`. We can simply work around this issue, by clipping
resulting negative values to 0 (and raising a notice in this case), because
the reasonable range for this value is certainly catered to by positive
`int`s.
However, there still remains the issue that `xml_parser::toffset` is later
added to `char *`s, which can cause OOB reads, so we make sure that the
upper bound never exceeds the strlen(). We eschew optimizing `SKIP_TAGSTART`
wrt. to the potentially duplicate strlen() call, because that code path is
unexpected anyway.

I've left litespeed alone, as it seems to genuinely maintain support
for many PHP versions.
bug32001.phpt has a high failure rate for the submitted reports. According to
several samples it seems the iconv implementation of glibc 2.12 (released
2010-05) is the culprit. It seems appropriate to skip the test for such old
versions.
