offset for time part in UUIDs was 1/1000 of what it
should be. In other words, offset was off.

Also handle the case where we count into the future
when several UUIDs are generated in one "tick", and
then the next call is late enough for us to unwind
some but not all of those borrowed ticks.

Lastly, handle the case where we keep borrowing and
borrowing until the tick-counter overflows by also
changing into a new "numberspace" by creating a new
random suffix.

  Show that time-part of UUIDs is correct now

  Results also decode to expect date-data on
  command-line (external validation).
  
  No test for unwinding of borrowed ticks as
  this a) is a race and b) depends on what timer
  we get.
sql/item_strfunc.cc:
  correct offset for date/time-part of UUID.
  also make sure that when we counted into
  the future earlier (several UUIDs generated
  in same tick), we only give back as many
  "borrowed" ticks as we can without duplicating
  past timestamps. If our tick-counter overflows
  before we can give back, or if the system-clock
  is set back (by user or Daylight Saving Time),
  we create a new random suffix to avoid
  collisions and clear the tick-counter.

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.


sql/log_event.cc:
  Aborting execution of event if fix_fields() fails since execution
  of update_hash() might cause a crash.

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.

   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.

Normalize directory names before adding them to default_directories.


mysys/default.c:
  Normalize directory names with unpack_dirname() before adding them
  to default_directories.  This way, /etc/ and /etc will not count as
  duplicates.
  
  Because this entails allocating memory to store the normalized names,
  add error handling and ensure that it doesn't leak memory in case
  both my_print_defaults() and load_defaults() are called.
  
  Clean up the Windows code that finds the exe's parent directory, and
  pull it out into a separate function.
  
  Reorganize the code into a single init_default_directories() function,
  with internal #ifdefs, instead of init_default_directories_<system>()
  functions which were accessed via a function pointer.  This is more in
  line with normal MySQL coding style, and easier to read for some.

   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
