unique index cannot be upgrade to primary index even if there
is no primary index already defined. Also fix possible corruption
when initialize "ref_length" value in case there is a mismatch
between MySQL and InnoDB primary key. Fix bug #51378: "Init
'ref_length' to correct value, in case an out of bound MySQL
primary_key".

TODO: We might also consider removing recv_max_parsed_page_no, because
it does not make much sense with *.ibd files.
recv_report_corrupt_log(), recv_scan_log_recs(): Abort when a
corrupted log record has been found, unless innodb_force_recovery has
been set.
This fixes Issue #464.

This should fix Mantis Issue #461.
innodb.test, innodb.result, innodb-index.test, innodb-index.result:
Adjust the test result and mention that the introduced restriction
has been reported as MySQL Bug #51451.
innobase_check_index_keys(): Add a parameter for the InnoDB table and
check that no duplicate index name is added. Report errors by
my_error() instead of sql_print_error().

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.
row_merge_dup_report(): Allocate buf and offsets from a heap.
row_merge_heap_create(): Allocate space for buf[3] too. Fix bogus
sizeof arithmetics that happened to work, because
sizeof(ulint)==sizeof(void*).
row_merge_blocks(), row_merge_blocks_copy(): Allocate buf[3] from heap.
row_merge_insert_index_tuples(): Allocate buf from graph_heap.

branches/5.1: Fix bug #50691, AIX implementation of readdir_r
causes InnoDB errors. readdir_r() returns an non-NULL value
in the case of reaching the end of a directory. It should
not be treated as an error return.

problems with concurrency on SMP systems because of word packing issues.
The number of trx_t's in a system is not sufficient enough to require that
we try and save a few bytes in the data structure.
See rb://255 for details.
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.

btr_pcur_open_with_no_init() is a macro, do not mix preprocessor
directives in the macro invocation, because it is implementation-defined
whether that is going to work.

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.
