When passing a NULL list to xmlNodeListGetString or

behavior.

Remove xmlAllocOutputBufferInternal which was identical to
xmlAllocOutputBuffer.

bc14d70f49 xmlsave: Improve "unsupported encoding" error message 
Incomplete support of XML_SAVE_* error codes was removed. Error handling
still needs work. xmlOutputBufferCreateFilename should return an error
code.

1a89323039 [CVE-2024-40896] Fix XXE protection in downstream code 
Some users set an entity's children manually in the getEntity SAX
callback to restrict entity expansion. This stopped working after
renaming the "checked" member of xmlEntity, making at least one
downstream project and its dependants susceptible to XXE attacks.

See #761.

The checks didn't handle stdout.

Since unistd.h wasn't included, W_OK wasn't defined and the checks

undefined if a symbol wasn't found, it has to be set to 0.

4f08a1a249 globals: Also use thread-specific storage on "main" thread 
Don't treat "main" thread specially. This simplifies access to
thread-specific data.

xmlGetGlobalState can now also fail on the former main thread, leading
to an unrecoverable condition if malloc fails.

The globals were never defined in public header files when compiling
with thread support. Now they're only defined in a legacy build.

Move TlsFree to DllMain to make cleanup more robust on Windows.

Obsoletes #1.

"size" still includes the terminating NULL byte.

Make xmlSetBufferAllocationScheme, xmlBufferAllocScheme and
xmlDefaultBufferSize no-ops.

Deprecate a few functions.
