Hi hackers,

there are a very long discuss about TDE, and we agreed on that if the
temporary file I/O can be aligned to some fixed size, it will be easier
to use some kind of encryption algorithm.

discuss:

This patch adjust file->curOffset and file->pos before the real IO to
ensure the start offset is aligned.
