Before this fix, the lexer and parser would treat the ';' character as a
different token (either ';' or END_OF_INPUT), based on convoluted logic,
which failed in simple cases where a stored procedure is implemented as a
single statement, and used in a multi query.

With this fix:
- the character ';' is always parsed as a ';' token in the lexer,
- parsing multi queries is implemented in the parser, in the 'query:' rules,
- the value of thd->client_capabilities, which is the capabilities
  negotiated between the client and the server during bootstrap,
  is immutable and not arbitrarily modified during parsing (which was the
  root cause of the bug)

On certain kinds of errors (e.g., out of stack), a call to Item_func_
set_user_var::fix_fields() might fail.  Since the return value of this
call was not checked inside User_var_log_event::exec_event(), continuing
execution after this will cause a crash inside Item_func_set_user_var::
update_hash().

The bug is fixed by aborting execution of the event with an error if
fix_fields() fails, since it is not possible to continue execution anyway.

	to use ANSI_QUOTES

Make all have_* tests universally safe by using ANSI quotes.

Test was failing due to the addition of a '\x05' character in result sets
Latest builds of the server have shown this problem to have disappeared.
Removing code within the test that disables the test on Mac OS X.

Recommit due to tree error on earlier, approved patch.

   Bug#36787 Test funcs_1.charset_collation_1 failing
Details:
1. Skip charset_collation_1 if charset "ucs2_bin" is
   missing (property which distincts "vanilla" builds
   from the others)
2. Let builds with version_comment LIKE "%Advanced%"
   (found them for 5.1) execute charset_collation_3.
3. Update comments charset_collation.inc so that they
   reflect the current experiences.

      
Bug#35658 (An empty binary value leads to mysqld crash)
        
Before this fix, the following token
  b''
caused the parser to crash when reading the binary value from the empty string.
The crash was caused by:
  ptr+= max_length - 1;
because max_length is unsigned and was 0, causing an overflow.
        
With this fix, an empty binary literal b'' is parsed as a binary value 0,
in Item_bin_string.

   Bug#37167 funcs_1: Many tests fail if the embedded server is used.
   Bug#37164 funcs_1: Some tests fail if an optional character set is missing.
+ some cleanup within the testsuite related to the fixes above
+ some adjustments to open bugs on Mac OS X

Details:
- Remove the initial loading of data from tests if these data
  are not somewhere retrieved
- Remove any use of columns with attribute unicode
  (-> UCS2 is no more needed) from tests where unicode
  properties are not checked or somehow required
- Create a separate branch of the Character maximum length test
  (CML). If UCS2 is available than this test gets applied to
  every available type of string column with attribute unicode
  This prevents any loss of coverage by the points above.
- Disable the execution of is_tables_ndb which gives wrong
  results because of a bug. Correct the exepected results of
  this test.
- In case of tests failing when applied to the embedded server
    1) Create a variant of this test for the embedded server
  or
    2) Skip the test in case of embedded server
  depending on purpose and complexity of test.
- Skip the tests which could suffer from
  Bug 28309 First insert violates unique constraint - was "memory" table empty ?
  Bug 37380 Test funcs_1.is_columns_myisam_embedded fails on OS X
  (both bugs Mac OS X, embedded server, MySQL 5.0 only)
- Minor improvements like remove typos

and the build tag for 5.0.62.

Fix for this bug and additional improvements/fixes
In detail:
- Remove unicode attribute from several columns
  (unicode properties were nowhere needed/tested)
  of the table tb3
  -> The runnability of these tests depends no more on
     the availibility of some optional collations.
- Use a table tb3 with the same layout for all
  engines to be tested and unify the engine name
  within the protocols.
  -> <engine>_trig_<abc>.result have the same content
- Do not load data into tb3 if these rows have no
  impact on result sets
- Add tests for NDB (they exist already in 5.1)
- "--replace_result" at various places because
  NDB variants of tests failed with "random" row
  order in results
  This fixes a till now unknown weakness within the
  funcs_1 NDB tests existing in 5.1 and 6.0
- Fix the expected result of ndb_trig_1011ext
  which suffered from Bug 32656
  + disable this test
- funcs_1 could be executed with the mysql-test-run.pl
  option "--reorder", which saves some runtime by
  optimizing server restarts.
  Runtimes on tmpfs (one attempt only):
  with    reorder 132 seconds
  without reorder 183 seconds
- Adjust two "check" statements within func_misc.test
  which were incorrect (We had one run with result set
  difference though the server worked good.)
- minor fixes in comments

Fix for this bug and a second similar problem
found during experimenting.

This replaces the first fix (already pushed to 5.1
and merged to 6.0) which
- failed in runs with the embedded server
- cannot be ported back to 5.0

Thanks to Paul for preparing the up-to-date files
reflecting 4.1 changes.

There was a typo in a error check causing wrong thing to be ckecked 
and a possible error not being caught.
Fixed by using the correct variable to test for malloc() errors.
