Fix cast-align warnings
- Suppress warnings in xmlmemory.c by casting to 'void *'.
- Remove unneeded cast in xmlschemas.c that caused a macro precedence
error.
- Add dummy fields to short structs in xmlschemas.c. This increases the
size of the structs, but I can't see a better solution without using
C11's _Alignof operator.
There are still a couple of cast-align warnings in encoding.c. These
are legitimate portability issues that can't be fixed without reworking
the conversion functions.
