Matthias Leich mleich@mysql.com 00c19cd837 Fix for 
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
