a8a757c6bb wl#173 - temporal types with sub-second resolution 
and collateral changes.

* introduce my_hrtime_t, my_timediff_t, and conversion macros
* inroduce TIME_RESULT, but it can only be returned from Item::cmp_type(),
  never from Item::result_type()
* pack_time/unpack_time function for "packed" representation of
  MYSQL_TIME in a longlong that can be compared
* ADDTIME()/SUBTIME()/+- INTERVAL now work with TIME values
* numbers aren't quoted in EXPLAIN EXTENDED
* new column I_S.COLUMNS.DATETIME_PRECISION
* date/time values are compares to anything as date/time, not as strings or numbers.
* old timestamp(X) is no longer supported
* MYSQL_TIME to string conversion functions take precision as an argument
* unified the warnings from Field_timestamp/datetime/time/date/newdate store methods
* Field_timestamp_hires, Field_datetime_hires, Field_time_hires
* Field_temporal
* Lazy_string class to pass a value (string, number, time) polymorphically down the stack
* make_truncated_value_warning and Field::set_datetime_warning use Lazy_string as an argument, removed char*/int/double variants
* removed Field::can_be_compared_as_longlong(). Use Field::cmp_type() == INT_RESULT instead
* introduced Item::cmp_result() instead of Item::is_datetime() and Item::result_as_longlong()
* in many cases date/time types are treated like other types, not as special cases
* greatly simplified Arg_comparator (regarding date/time/year code)
* SEC_TO_TIME is real function, not integer.
* microsecond precision in NOW, CURTIME, etc
* Item_temporal. All items derived from it only provide get_date, but no val* methods
* replication of NOW(6)
* Protocol::store(time) now takes the precision as an argument
* @@TIMESTAMP is a double

  not always Field_timestamp, see events_1.test)
sql/event_queue.cc:
  avoid silly double-work for cond_wait
  (having an endpoint of wait, subtract the current time to get the timeout,

  mention all possibitiles in switch over Item_result values, or use default:
sql/item_row.h:
  overwrite the default cmp_type() for Item_row,
  as no MYSQL_TYPE_xxx value corresponds to ROW_RESULT
sql/item_timefunc.cc:
  rewrite make_datetime to support precision argument
  SEC_TO_TIME is real function, not integer.
  many functions that returned temporal values had duplicate code in val_* methods,
  some of them did not have get_date() which resulted in unnecessary date->str->date conversions. 
  Now they all are derived from Item_temporal_func and *only* provide get_date, not val* methods.
  many fixes to set decimals (datetime precision) correctly.

  TIMESTAMP no longer carries ZEROFIELD flag, still we keep MYI file compatible.

  warnings

  old timestamp(X) does not work anymore
  datetime is no longer equal to time

5b7347bda3 Bug#29125 Windows Server X64: so many compiler warnings 
- Remove bothersome warning messages.  This change focuses on the warnings 
that are covered by the ignore file: support-files/compiler_warnings.supp.
- Strings are guaranteed to be max uint in length

02f305516f Bug#35981: ALTER EVENT causes the server to change the PRESERVE option. 
If [NOT] PRESERVE was not given, parser always defaulted to NOT
PRESERVE, making it impossible for the "not given = no change"
rule to work in ALTER EVENT. Leaving out the PRESERVE-clause
defaults to NOT PRESERVE on CREATE now, and to "no change" in
ALTER.

mysql-test/r/events_2.result:
  show that giving no PRESERVE-clause to ALTER EVENT
  results in no change. show that giving no PRESERVE-clause
  to CREATE EVENT defaults to NOT PRESERVE as per the docs.
  Show specifically that this is also handled correctly when
  trying to ALTER EVENTs into the past.
mysql-test/t/events_2.test:
  show that giving no PRESERVE-clause to ALTER EVENT
  results in no change. show that giving no PRESERVE-clause
  to CREATE EVENT defaults to NOT PRESERVE as per the docs.
  Show specifically that this is also handled correctly when
  trying to ALTER EVENTs into the past.
sql/event_db_repository.cc:
  If ALTER EVENT was given no PRESERVE-clause (meaning "no change"),
  we don't know the previous PRESERVE-setting by the time we check
  the parse-data. If ALTER EVENT was given dates that are in the past,
  we don't know how to react, lacking the PRESERVE-setting. Heal this
  by running the check later when we have actually read the previous
  EVENT-data.
sql/event_parse_data.cc:
  Change default for ON COMPLETION to indicate, "not specified."
  Also defer throwing errors when ALTER EVENT is given dates in
  the past but not PRESERVE-clause until we know the previous
  PRESERVE-value.
sql/event_parse_data.h:
  Add third state for ON COMPLETION [NOT] PRESERVE (preserve,
  don't, not specified).
  
  Make check_dates() public so we can defer this check until
  deeper in the callstack where we have all the required data.
sql/sql_yacc.yy:
  If CREATE EVENT is not given ON COMPLETION [NOT] PRESERVE,
  we default to NOT, as per the docs.

3cf9e6eb6b Bug#35997 Event scheduler seems to let the server crash, if it is embedded.

patch disables and excludes the event scheduler when the server is
compiled for embedded build.


libmysqld/Makefile.am:

  Disable test if run in embedded mode.
sql/Makefile.am:
  Introduce definition HAVE_EVENT_SCHEDULER and one new source file.
sql/event_data_objects.cc:
  Refactor Event_parse_data to new file.
sql/event_data_objects.h:
  Refactor Event_parse_data to new file.
  Move global definitions to new file.
sql/event_queue.cc:
  Move all parsed items to Event_parse_data for easier modularization.
sql/events.cc:
  Move all parsed items to Event_parse_data for easier modularization.
sql/mysqld.cc:
  Disable the event schedular subsystem if the server is compiled in
  embedded mode.
sql/set_var.cc:
  Disable the event schedular subsystem if the server is compiled in
  embedded mode.
sql/set_var.h:
  Disable the event schedular subsystem if the server is compiled in
  embedded mode.
sql/sql_db.cc:

  embedded mode.
sql/sql_test.cc:
  Disable the event schedular subsystem if the server is compiled in
  embedded mode.
sql/sql_yacc.yy:
  Only include event-code needed for parsing to reduce impact on embedded
  build.
  Move all constants to Event_parse_data class.
mysql-test/r/events_embedded.result:
  Add test case to make sure the 'event_scheduler' can't be activated
  in embedded mode.
mysql-test/r/is_embedded.require:
  Add test case to make sure the 'event_scheduler' can't be activated
  in embedded mode.
mysql-test/t/events_embedded.test:
