regexp: Fix determinism checks
Swap arguments in initial call to xmlFARecurseDeterminism.
Fix the check whether we revisit the initial state in
xmlFARecurseDeterminism.
If there are transitions with equal atoms and targets but different
counters, treat the regex as deterministic but mark the transitions as
non-deterministic internally.
Don't overwrite zero return value of xmlFAComputesDeterminism
with non-zero value from xmlFARecurseDeterminism.
Most of these errors lead to non-deterministic regexes not being
detected which typically isn't an issue. The improved code may break
users who relied on buggy behavior or cause other bugs to become
visible.
Fixes #469.

Now we convert the first 200 bytes to EBCDIC-US and parse the encoding
declaration manually.

malloc-fail: Stop using XPath stack frames
There's too much code which assumes that if ctxt->value is non-null,
a value can be successfully popped off the stack. This assumption can
break with stack frames when malloc fails.
Instead of trying to fix all call sites, remove the stack frame logic.
It only offered very little protection against misbehaving extension
functions. We already check the stack size after a function call which
should be enough.
