encoding: Clean up UCS-4 encodings
...
Use "UCS-*" instead of "ISO-10646-UCS-*". While the XML spec recommends
"ISO-10646-UCS-2" and "ISO-10646-UCS-4", GNU iconv doesn't understand
these names.
Ignore UCS4_2143 and UCS4_3412 which were never supported.

reader: Fix return value of xmlTextReaderReadString again
...
Make sure to return NULL for node types except elements or text to match
the old behavior.
Note that CDATA sections are still treated like text nodes and will have
their content returned.
Fixes #838 .

memory: Implement xmlGrowCapacity to safely grow arrays
...
xmlGrowCapacity makes sure that dynamic arrays don't grow beyond an
explicit maximum size. size_t considerations are also taken into account.
A macro XML_MAX_ITEMS is provided as default maximum with value
1 billion.
When fuzzing, the initial size is set to 1 to cause more reallocations.
This can require adjustments if callers really need larger arrays.
