Subject: [PATCH 1/2] libxml: include parser.h

libxml2 removed the inclusion of global.h in a few of its include files,
so we can no longer rely on transitive includes.

This applies to functions like xmlParseFile.

Subject: [PATCH 2/2] libxml: constify the storage of xmlGetLastError()

libxml2 recently made it a const return.
Since nothing is being modified of it, this should have no real effect
past satisfying the compiler.
