tree: Don't coalesce text nodes in xmlAdd{Prev,Next}Sibling
Commit 9e1c72da from 2001 introduced a bug where xmlAddPrevSibling and
xmlAddNextSibling would only try to merge text nodes with one of its
new siblings. Commit 4ccd3eb8 fixed this bug but unfortunately, lxml
and possibly other downstream code depend on text nodes not being
merged.
To avoid breaking downstream code while still having somewhat
consistent API behavior, it's probably best to make these functions
never coalesce text nodes.

Fix exponential runtime and memory in xi:fallback processing
When creating XML_XINCLUDE_START nodes, the children of the original
xi:include node must be freed, otherwise fallback content is copied
twice, doubling runtime and memory consumption for each nested
xi:fallback/xi:include pair.
Found with libFuzzer.
