* Do length/capacity checks in every read/write/seek function
if WINPR_ASSERT is defined.
* Ensure s->pointer is valid, e.g. within s->buffer + s->capacity
(Stream_Rewind, Stream_Seek, ...)
* Add return values to Stream_Set* functions so inalid arguments
can be reported to the caller
* Deprecated problematic stream manipulation functions
(Stream_SetBuffer, Stream_SetPointer, Stream_SetCapacity)
* Ensure length/capacity functions never return a value larger
than the actual length/capacity
