branches/zip: row_merge(): Remove a bogus debug assertion
that was triggered when creating an index on an empty table.

row_merge_sort(): Add debug assertions and comments that justify
the loop termination condition.

The bogus assertion ut_ad(ihalf > 0) was reported by Michael.

branches/zip: recv_recover_page_func(): Write the log sequence number
to the compressed page, if there is one.  Previously, the function only
wrote the LSN to the uncompressed page.

It is not clear why recv_recover_page_func() is updating FIL_PAGE_LSN
in the buffer pool.  The log sequence number will be stamped on the
page when it is flushed to disk, in buf_flush_init_for_writing().
I noticed this inconsistency when analyzing Issue #313, but this patch
does not fix it.  That is no surprise, since FIL_PAGE_LSN should only
matter on disk files, not in the buffer pool.

branches/zip: Build InnoDB on Windows with UNIV_HOTBACKUP

The changes are non-functional changes for normal InnoDB,
but needed for building the Hot Backup on Windows (with
UNIV_HOTBACKUP defined).

- Define os_aio_use_native_aio for HB.
- Do not acquire seek mutexes for backup since HB is single threaded.
- Do not use srv_flush_log_at_trx_commit for HB build
