The problem happened because Item_ident_for_show::field_type() always
returned MYSQL_TYPE_DOUBLE and ignored the actual data type of the
referenced Field. As a result, the execution always used
Item_ident_for_show::val_real() to send the default value of the field,
so most default values for non-numeric types were displayed as '0'.
This patch:
1. Cleanup:
a. Removes Send_field::charsetnr, as it's been unused since
introduction of Item::charset_for_protocol() in MySQL-5.5.
b. Adds the "const" qualifier to Field::char_length().
This is needed for (5.a), see below.
2. Introduces a new virtual method Type_handler::charset_for_protocol(),
returning item->collation.collation for string data types, or
&my_charset_bin for non-string data types.
3. Changes Item::charset_for_protocol() from virtual to non-virtual.
It now calls type_handler()->charset_for_protocol().
As a good side effect, duplicate code in Item::charset_for_protocol() and
Item_temporal_hybrid_func::charset_for_protocol() is now gone.
4. Fixes Item_ident_for_show::field_type() to correctly return
its data type according to the data type of the referenced field.
This actually fixes the problem reported in MDEV-11672.
Now the default value is sent using a correct method, e.g.
val_str() for VARCHAR/TEXT, or val_int() for INT/BIGINT.
This required additional changes:
a. in DBUG_ASSERT in Protocol::store(const char *,size_t,CHARSET_INFO),
This method is now used by mysqld_list_fields(), which
(unlike normal SELECT queries) does not set
field_types/field_pos/field_count.
b. Item_ident_for_show::Item_ident_for_show() now set standard attributes
(collation, decimals, max_length, unsigned_flag) according to the
referenced field, to make charset_for_protocol() return the correct
value and to make mysqld_list_fields() correctly send default
values.
5. In order to share the code between Item_field::set_field() and
Item_ident_for_show::Item_ident_for_show():
a. Introduces a new method Type_std_attributes::set(const Field*)
b. To make (a) possible, moves Item::fix_char_length() from Item
to Type_std_attributes, also moves char_to_byte_length_safe()
from item.h to sql_type.h
c. Additionally, moves Item::fix_length_and_charset() and
Item::max_char_length() from Item to Type_std_attributes.
This is not directly needed for the fix and is done just for symmetry
with fix_char_length(), as these three methods are directly related
to each other.

otherwise we'd need to store sql_mode *per vcol*
(consider CREATE INDEX...) and how SHOW CREATE TABLE would
support that?
Additionally, get rid of vcol::expr_str, just to make sure
the string is always generated and never leaked in the
original form.

Merge feature into 10.2 from feature branch.
Delayed replication adds an option
CHANGE MASTER TO master_delay=<seconds>
Replication will then delay applying events with that many
seconds. This creates a replication slave that reflects the state of
the master some time in the past.
Feature is ported from MySQL source tree.

- Removed some QQ markers
- Removed some rows not compatible with valgrind 3.9.0
- Made mysql_install_db.sh more silent by default. --verbose now gives more information
- Added assert that auto-increment doesn't generate 0 (safety)
- Removed thd->set_time() in some places as it's set in init_for_queries()
- Fixed some --big tests in tokudb
- Fixed a bug in mysql_client_test.cc where sql_mode was not properly reset

This includes fixing all utilities to not have any memory leaks,
as safemalloc warnings stopped tests from passing on MacOSX.
- Ensure that all clients takes character-set-dir, as the
libmysqlclient library will use it.
- mysql-test-run now passes character-set-dir to all external clients.
- Changed dynstr_free() so that it can be called twice (made freeing code easier)
- Changed rpl_global_gtid_slave_state to be allocated dynamicly as it
includes a mutex that needs to be initizlied/destroyed before my_end() is called.
- Removed rpl_slave_state::init() and rpl_slave_stage::deinit() as
their job are better handling by constructor and delete.
- Print alias instead of table_name in check_duplicate_key as
table_name may have been converted to lower case.
Other things:
- Fixed a case in time_to_datetime_with_warn() where we where
using && instead of & in tests

stat structure (from <sys/stat.h>) is conditionally defined
to have different layout and size depending on the defined macros.
The correct macro is defined in my_config.h, which means it MUST be
included first (or, at least before <features.h> - so, practically,
before including any system headers).

schema and big packets in debug version.
The bug was that my_real_read() called net_before_header_psi() multiple times for long packets.
Fixed by adding a flag when we are reading a header.
Did also some cleanups to interface of my_net_read() to avoid unnecessary calls if performance schema is not used.
- Added my_net_read_packet() as a replacement for my_net_read(). my_net_read() is still in the client library for old clients.
- Removed THD->m_server_idle (not needed anymore as this is now given as argument to my_net_read_packet()
- Added my_net_read_packet(), which is a new version of my_net_read() with a new parameter if we are doing a read for a new command from the server.
- Added tests for compressed protocol and big packets
