If the user has specified --max-connections=N or --table-open-cache=M
options to the server, a warning could be given that some values were
recalculated, and table-open-cache could be assigned greater value.

Note that both warning and increase of table-open-cache were totally
harmless.

This patch fixes recalculation code to ensure that table-open-cache will
be never increased automatically and that a warning will be given only if
some values had to be decreased due to operating system limits.

No test case is provided because we neither can't predict nor control
operating system limits for maximal number of open files.


sql/mysql_priv.h:
  Add constants for table_cache minimum and default values.
sql/mysqld.cc:
  Fix max_connections and table_cache_size re-computation.

If the error happens during DELETE IGNORE, nothing could be send to the
client, thus leaving it frozen expecting the reply.

The problem was that if some error occurred, it wouldn't be reported to
the client because of IGNORE, but neither success would be reported.

MySQL 4.1 would not freeze the client, but will report

  ERROR 1105 (HY000): Unknown error

instead, which is also a bug.

The solution is to report success if we are in DELETE IGNORE and some
non-fatal error has happened.

Repair table could crash a server if there is not sufficient
memory (myisam_sort_buffer_size) to operate. Affects not only
repair, but also all statements that use create index by sort:
repair by sort, parallel repair, bulk insert.

Return an error if there is not sufficient memory to store at
least one key per BUFFPEK.

Also fixed memory leak if thr_find_all_keys returns an error.


myisam/sort.c:
  maxbuffer is number of BUFFPEK-s for repair. It is calculated
  as records / keys. keys is number of keys that can be stored
  in memory (myisam_sort_buffer_size). There must be sufficient
  memory to store both BUFFPEK-s and keys. It was checked
  correctly before this patch. However there is another
  requirement that wasn't checked: there must be sufficient
  memory for at least one key per BUFFPEK, otherwise repair
  by sort/parallel repair cannot operate.
  
  Return an error if there is not sufficient memory to store at
  least one key per BUFFPEK.
  
  Also fixed memory leak if thr_find_all_keys returns an error.

   When resolving unqualified name references MySQL was not
   checking what is the item type for the reference. Thus
   e.g a string literal item that has by convention a name
   equal to its string value will also work as a reference to 
   a SELECT list item or a table field.
   Fixed by allowing only Item_ref or Item_field to referenced by
   (unqualified) name.
