Non-functional change.

The merge sort can use up to 48KiB of buffers when merging blocks.
That can cause a stack overflow, especially on 64-bit systems when not
building with inlined functions.  This was reported as Issue #462.

ChangeLog entry for r6674.

This is a backport of r4924.
mem_heap_get_size() scans all allocated blocks to calculate the total
size of the heap. This patch introduces a new, total_size, field in
mem_block_info_struct. This field is valid only for base block 
(i.e.: the first block allocated for the heap) and is set to
ULINT_UNDEFINED in other blocks.
This considerably improves the performance of redo scan during recovery.

------------------------------------------------------------------------

When rolling back an incomplete transaction in purge, tolerate missing
BLOBs also in update undo, when undoing an INSERT by updating a delete-marked
record, and the delete-marked record is no longer needed.
Previously, we only tolerated missing BLOBs in insert undo.
This merely fixes a debug assertion; the code performed correctly
without UNIV_DEBUG.

  InnoDB logs error repeatedly when trying to load page into buffer pool

  In buf_page_get_gen() if we are unable to read a page (because of
  corruption or some other reason) we keep on retrying. This fills up
  error log with millions of entries in no time and we'd eventually run
  out of disk space. This patch limits the number of attempts that we
  make (currently set to 100) and after that we abort with a message.
