moved to storage/innobase/

also removed duplicate checks from storage/innobase/CMakeLists.txt
(they're all in storage/innobase/innodb.cmake)

MDEV-11605 Assertion `(longlong) thd->status_var.local_memory_used >= 0 || !debug_assert_on_not_freed_memory' failed in my_malloc_size_cb_func

MyISAM in compute_vcols() - which is used only in mi_check code -
was computing indexed vcols into an internally allocated buffer
(not record[0]) and the buffer was calculated to be long enough to fit
every keyseg (a keyseg knows where its value in a record buffer is
and the length of the value).

This logic didn' work for prefix keys, because the keyseg length is the
length of a prefix, but the record buffer needs to fit the complete
value of a vcol. In this bug MyISAM was writing a 2K varchar
into a buffer too short.

Also it didn't work for repair-with-keycache, because that code
recalculats all vcols, not only indexed ones.

So, the buffer size (MYISAM_SHARE::vreclength) should include all
vcols' full lengths. But it was calculated in mi_open and low-level
MyISAM code has no knowledge of vcols.

As a fix we now recalculate MYISAM_SHARE::vreclength in
ha_myisam::setup_vcols_for_repair() which is always called
before compute_vcols().

MDEV-10354 Assertion `! is_set()' failed in Diagnostics_area::set_ok_status on CREATE TABLE with invalid default

test case

MDEV-11114 Cannot drop column referenced by CHECK constraint: Unknown column 'a' in 'virtual column function'

clarify the error message

add columns needed for CHECK constraints not only to read_set,
but also to vcol_set.

give threads more descriptive names

don't build the server with jemalloc.
only build tokudb with it.
move tokudb into a separate package, because it brings a new dependency

disable XtraDB in a way that makes it impossible to be built

* remove redundant casts
* fix fix_win_paths() not to pretend that it takes const char* string
  because it changes it. Fix its callers not to pass const strings
  into it.
* use _WIN32 not __WIN__

        Added IS_GENERATED and GENERATION_EXPRESSION columns required by
        the SQL standard

The function st_select_lex_unit::exec_recursive() incorrectly determined
that a CTE mutually recursive with some others was stabilized in the case
when the non-recursive part of the CTE returned an empty set. As a result
the server fell into an infinite loop when executing a query using
this CTE.

Do not truncate pointers returned by _findfirst to int.

Mutually recursive CTE could cause a crash of the server in the case
when they were not Standard compliant. The crash happened in
mysql_derived_prepare(), because the destructor the derived_result
object created for a CTE that was mutually recursive with some others
was called twice. Yet this destructor should not be called for resursive
references.

The method With_element::check_unrestricted_recursive() icorrectly performed
the check that no recursive reference is not encountered in inner parts of
outer joins. As a result the server reported errors for valid specifications
with outer joins.

This could fix a race condition between mysqld and perl on Windows.

The test was unnecessarily depending on InnoDB purge, which can
sometimes fail to proceed.

Let us rewrite the test to use BEGIN;INSERT;ROLLBACK to cause the
immediate removal of the desired records.

MDEV-12328, added building of AWS for release builds

instance connects to server.

        New thread kill status added KILL_SLAVE_SAME_ID, and the related
        error message.

On some weird reason, Visual C++ does not like newly introduced
#define ut_ad(EXPR)	DBUG_ASSERT(EXPR)

and writes bogus "not enough parameters for DBUG_ASSERT" warning.

Workaround it with
#define ut_ad DBUG_ASSERT

JSON_REMOVE.

        null_value wasn't properly set in Item_json_func_remove::val_str.

After a partial rollback, an undo log segment that is empty
may carry a duplicate-looking top_undo_no.

Adjust the debug assertions and add a test.

When "simulate_failed_connection_1"  DBUG keyword is set, current thread's
DBUG stack points to global variable in dbug (init_settings).
This global variable could be overriden while current THD is still active,
producing crash in worst scenario.

Added DBUG_SET()so that the current thread own dbug
context that cannot concurrently modified by anyone else.

Bug#21141390: REMOVE UNUSED FUNCTIONS AND CONVERT GLOBAL SYMBOLS TO STATIC
but for variables instead of functions.

Was identified with the -Wmissing-variable-declarations
compiler warning option supported by Clang 3.6.

InnoDB defines some functions that are not called at all.
Other functions are called, but only from the same compilation unit.

Remove some function declarations and definitions, and add 'static'
keywords. Some symbols must be kept for separately compiled tools,
such as innochecksum.

Also, remove empty .ic files that were not removed by my MySQL commit.

Problem:
InnoDB used to support a compilation mode that allowed to choose
whether the function definitions in .ic files are to be inlined or not.
This stopped making sense when InnoDB moved to C++ in MySQL 5.6
(and ha_innodb.cc started to #include .ic files), and more so in
MySQL 5.7 when inline methods and functions were introduced
in .h files.

Solution:
Remove all references to UNIV_NONINL and UNIV_MUST_NOT_INLINE from
all files, assuming that the symbols are never defined.
Remove the files fut0fut.cc and ut0byte.cc which only mattered when
UNIV_NONINL was defined.
