MDEV-12533 sql_mode=ORACLE: Add support for database qualified sequence names in NEXTVAL and CURRVAL

Recording correct test results in funcs_1.myisam_trig_0407, related to the recent "Trigger already exists" change.

- Added trigger name to "Trigger already exists" error message
- Added also missing query name to ER_DUP_QUERY_NAME
- Fixed wrong use of MASTER_DELAY_VALUE_OUT_OF_RANGE

This was wrong because:
- There was no reason to rollback name for item that will be deleted
  after query.
- name_length was not rolled back
- Changing real_item() doesn't work as it may be used many times in the
  same query

After removing all the old code and extending the test case, all the
related test cases passes.

Sanja and I concluded that the old code isn't needed anymore.  If it
still needed for some scenario not covered by our test system, it needs
to be coded in some other way, so better to remove the wrong code.

This patch implements MDEV-12514 according to the task descriptions.
It automatically fixes:
MDEV-12515 Wrong value when storing DATE_ADD() and ADDTIME() to a numeric field

Additionally:

a. Moves Item_func::set_attributes_temporal() to
   Type_str_attributes::fix_attributes_temporal(),
  which is a more proper place and name for it.

b. Continues replacing calls for:
     set_handler_by_field_type(MYSQL_TYPE_XXX)
   to corresponding:
     set_handler(&type_handler_xxx)
   which is faster.
   Note, we should eventually get rid of almost all set_handler_by_field_type().

c. Makes type_handler_string, type_handler_time2, type_handler_newdate,
   type_handler_datetime2 public.
   (all built-in handlers will become public eventually)

d. Removing Item_temporal_func::sql_mode, as it was not used.

Remove some DBUG_ASSERT that can happen if mysqlcheck is called with
a view as argument

This was done to make it clear that a update_row() should not change the
row.
This was not done for handler::write_row() as this function still needs
to update auto_increment values in the row. This should at some point
be moved to handler::ha_write_row() after which write_row can also have
const arguments.

This was done when static int where used as bit fields or enums

Fixed compiler warning
Added comment

Remove clang-3.8 which doesn't have a repository on apt.llvm.org any
more.

For OSX, xcode8.3 is explicitly specified.

/usr/local/Cellar is used as a cache repository to save brew install
time on OSX (and /usr/local was too big).

Debian autobake.sh is moved to a matrix include.

Other branches of the matrix build test other test suites.
An Ubuntu galera is downloaded and used in the test suite.

TYPE=RelWithDebInfo used with the test to provide backtraces with line
numbers when crashes occur.

Build of PLUGIN_AWS_KEY_MANAGEMENT enabled in build.

Code supporting TYPE=Debug and -DWITH_ASAN=ON included by not enabled
due to large numbers of errors.

Running more tests in parallel (6) as container based builds seem to
support them. The test case timeout has been set to 2 minutes as large
stalls will put test cases over 50 minute interval.

ccache enabled where possible. Linux clang builds don't use them as the
minimum CMake version isn't there.

Problem was that we got an error in sequence_insert while opening the
newly created sequence table in an prepared statement as the table id
didn't match.
Fixed by temporarly removing the reprepare observer during
sequence_insert as there can never be a table missmatch in this case.

storage/rocksdb/rdb_datadic.cc failed to compile on big endian machines (wrong usage of static_assert)

Data loss in case of partituon removing is documented => do not try to prevent it

In case of error on opening VIEW (absent table for example) it is still possible to print its definition but some variable is not set (table_list->derived->derived) so it is better do not try to test it when there is safer alternative (table_list itself).

- Don't call my_chsize() for small (less than 64K) binary log tmp files
- Don't flush cache to disk on reset.

- Added file name to error in mysql-test-run
- When creating tags, first do it for sql to make it easier to find things in server
