5a10ee2721 branches/zip: Add function mtr_memo_contains_page() #ifdef UNIV_DEBUG.
Replace ut_ad(mtr_memo_contains(mtr, buf_block_align(ptr), ...))
with ut_ad(mtr_memo_contains_page(mtr, ptr, ...)) in order to reduce the
number of buf_block_align() calls.

ee5a92aaef branches/zip: Implement the compression of BLOB columns.
This has not been extensively tested yet, because some other part of the
code breaks in "ibtestblob".
