by default we never run disabled tests (even if they're
explicitely listed on the command-line). We add an option --enable-disabled
which will run tests even though they are disabled, and will print, for each
such test, the comment explaining why it was disabled.
The reason for the change is when you want to run "all tests which are about
NDB" for example: mysql-test-run.pl t/*ndb*.test used to run some disabled
NDB tests, causing failures, causing investigations.
Code amended and approved by Kent.


mysql-test/lib/mtr_cases.pl:
  always detect if a test is listed as disabled, and read the comment why is is.
  If it is listed, don't run the test, except if
  --enable-disabled was given, then mark the test as to-run-even-
  though-it-is-listed-as-disabled.
mysql-test/lib/mtr_report.pl:
  Report tests which will run though they are listed as disabled
  (does something only if --enable-disabled).
mysql-test/mysql-test-run.pl:
  New behaviour: by default we never run disabled tests (even if they're
  explicitely listed on the command-line). We add an option --enable-disabled
  which will run tests even though they are disabled, and will print, for each
  such test, the comment explaining why it was disabled.

though unneeded". It's indeed unneeded, as slave is only interested in
permanent tables, and permanent tables don't depend on temporary tables
when in row-based binlogging mode. And other CREATE TEMPORARY TABLE
(referring no table or with LIKE) already don't write the CREATE to
binlog in row-based mode. 


mysql-test/r/rpl_row_create_table.result:
  result update (note that no lines appear in SHOW BINLOG EVENTS further below, which is how we
  see the bug is fixed)
mysql-test/t/rpl_row_create_table.test:
  testing if a CREATE TEMPORARY TABLE SELECT goes to binlog (it should not)
  when in row-based binlogging mode. A few lines after, there is a SHOW
  BINLOG EVENTS; before the bugfix it showed the CREATE TEMPORARY TABLE.
sql/sql_class.h:
  a method to access select_create::create_info from outside of select_create
  ("read-only" access). Making get_thd() "read-only" too.
sql/sql_insert.cc:
  The function (hook) which writes CREATE TABLE to binlog when in row-based
  binlogging mode, for CREATE TABLE SELECT, now does nothing if the table
  is temporary (as in row-based mode, temp tables are not replicated).
  This is consistent with CREATE TEMPORARY TABLE LIKE and
  CREATE TEMPORARY TABLE, which don't write any CREATE to binlog in row-based
  mode.

  Manual merge

The intermediate (not temporary) files of the new table
during ALTER TABLE was visible for SHOW TABLES. These
intermediate files are copies of the original table with
the changes done by ALTER TABLE. After all the data is
copied over from the original table, these files are renamed 
to the original tables file names. So they are not temporary 
files. They persist after ALTER TABLE, but just with another 
name.

Normal GRANT checking takes place for the intermediate table.
Everyone who can see the original table (and hence the final
table) can also see the intermediate table. But noone else.

In 5.0 the intermediate files are invisible for SHOW TABLES
because all file names beginning with "#sql" were suppressed.
In 5.1 temporary files are created in TMPDIR, so that they
don't appear in the database directories. Also in 5.1 a
translation between table names and file names is done. The
tmp_file_prefix on file level is now "@0023sql".

The suppression of files starting with tmp_file_prefix is
still in place, but still only files beginning with "#sql"
were suppressed.

I do now translate tmp_file_prefix from table name to file
name before comparing it with the files in a directory.
This suppresses the intermediate files again.

No test case. The test case looks so that a reasonable big
table is altered while a second thread runs SHOW TABLES.
This in itself would be possible to do, but on slow machines
it would add too much time to the test suite, while on fast
machines the ALTER TABLE might have finished before SHOW
TABLES looks at the directory. Even if there might be a good
balance for todays machines, one day the test would become
void as the intermediate table would not be seen even with
the bug in place. I added a test script to the bug report.
It can easily be changed so that it uses a table size that
is appropriate for the test machine.
