be consistent and don't include the table name into the error message,
no other CREATE TABLE error does it.
(the crash happened, because thd->lex->query_tables was NULL)
Print default values for BLOB's.
This is a part commit for automatic changes to make the real commit smaller.
All changes here are related to that we now print DEFAULT NULL for blob and
text fields, like we do for all other fields.
In original code, sometimes one got an automatic DEFAULT value in some cases, in other cases not.
For example:
create table t1 (a int primary key) - No default
create table t2 (a int, primary key(a)) - DEFAULT 0
create table t1 SELECT .... - Default for all fields, even if they where defined as NOT NULL
ALTER TABLE ... MODIFY could sometimes add an unexpected DEFAULT value.
The patch is quite big because we had some many test cases that used
CREATE ... SELECT or CREATE ... (...PRIMARY KEY(xxx)) which doesn't have an automatic DEFAULT anymore.
Other things:
- Removed warnings from InnoDB when waiting from semaphore (got this when testing things with --big)
that is, after

be less annoying about sysvar-based table attributes
do not *always* add them to the create table definition,
but only when a sysvar value is different from a default.
also, when adding them - don't quote numbers
MDEV-5839 TokuDB tables not properly cleaned on DROP DATABASE
TokuDB does not support discover_table_names() and writes no files
in the database directory, so automatic filename-based
discover_table_names() doesn't work either. So, it must force .frm
file to disk in ::create()
sql/create_options.cc:
an utility function to compare two filled-in engine_option structures
sql/sql_table.cc:
* two keys are different if their option_struct's differ
(for ALTER TABLE DROP key, ADD key)
* engines doing inplace alter must see the new frm image
