column exists in existing foreign key relation

by CREATE TABLE statement to check nullability for foreign

Some .c and .cc files are compiled as part of Mariabackup.
Enabling -Wconversion for InnoDB would also enable it for
Mariabackup. The .h files are being included during
InnoDB or Mariabackup compilation.
Notably, GCC 5 (but not GCC 4 or 6 or later versions)
would report -Wconversion for x|=y when the type is
unsigned char. So, we will either write x=(uchar)(x|y)
or disable the -Wconversion warning for GCC 5.
bitmap_set_bit(), bitmap_flip_bit(), bitmap_clear_bit(), bitmap_is_set():
Always implement as inline functions.
With MAX_INDEXIES=64(default), key_map=Bitmap<64> is just a wrapper around
ulonglong and thus "trivial" (can be bzero-ed, or memcpy-ed, and stays
valid still)
With MAX_INDEXES=128, key_map = Bitmap<128> is not a "trivial" type
anymore. The implementation uses MY_BITMAP, and MY_BITMAP contains pointers
which make Bitmap invalid, when it is memcpy-ed/bzero-ed.
The problem in 10.4 is that there are many new key_map members, inside TABLE
or KEY, and those are often memcopied and bzeroed
The fix makes Bitmap "trivial", by inlining most of MY_BITMAP functionality.
pointers/heap allocations are not used anymore.
main.derived_cond_pushdown: Move all 10.3 tests to the end,
trim trailing white space, and add an "End of 10.3 tests" marker.
Add --sorted_result to tests where the ordering is not deterministic.
main.win_percentile: Add --sorted_result to tests where the
ordering is no longer deterministic.
- Added sql/mariadb.h file that should be included first by files in sql
directory, if sql_plugin.h is not used (sql_plugin.h adds SHOW variables
that must be done before my_global.h is included)
- Removed a lot of include my_global.h from include files
- Removed include's of some files that my_global.h automatically includes
- Removed duplicated include's of my_sys.h
- Replaced include my_config.h with my_global.h
Define my_thread_id as an unsigned type, to avoid mismatch with
ulonglong. Change some parameters to this type.
Use size_t in a few more places.
Declare many flag constants as unsigned to avoid sign mismatch
when shifting bits or applying the unary ~ operator.
When applying the unary ~ operator to enum constants, explictly
cast the result to an unsigned type, because enum constants can
be treated as signed.
In InnoDB, change the source code line number parameters from
ulint to unsigned type. Also, make some InnoDB functions return
a narrower type (unsigned or uint32_t instead of ulint;
bool instead of ibool).
* make a local variable for target_table->field[col]
* move an often-used bit function to my_bit.h
* remove a non-static and not really needed trivial comparison
function with a very generic name

Assertion `bitmap_is_set_all(&table->s->all_set)' failed in
handler::ha_reset
This assertion could be triggered if two connections simultaneously
executed two bitmap test functions on the same bitmap. For example,
the assertion could be triggered if one connection executed UPDATE
while a second connection executed SELECT on the same table.
Even if bitmap test functions have read-only semantics and have
const bitmaps as parameter, several of them modified the internal
state of the bitmap. With interleaved execution of two such functions
it was possible for one function to modify the state of the same
bitmap that the other function had just modified. This lead to an
inconsistent state and could trigger the assert.
Internally the bitmap uses 32 bit words for storage. Since bitmaps
can contain any number of bits, the last word in the bitmap may
not be fully used. A 32 bit mask is maintained where a bit is set
if the corresponding bit in the last bitmap word is unused.
The problem was that several test functions applied this mask to
the last word. Sometimes the mask was negated and used to zero out
the remainder of the last word and sometimes the mask was used as-is
to fill the remainder of the last word with 1's. This meant that if
a function first used the negated mask and another function then
used the mask as-is (or vice-versa), the first function would then
get the wrong result.
This patch fixes the problem by changing the implementation of
9 bitmap functions that modified the bitmap state even if the
bitmap was declared const. These functions now preserve the
internal state of the bitmap. This makes it possible for
two connections to concurrently execute two of these functions
on the same bitmap without issues.
The patch also removes dead testing code from my_bitmap.c.
These tests have already been moved to unittest/mysys/bitmap-t.c.
Existing test coverage of my_bitmap has been extended.
No MTR test case added as this would require adding several sync
points to the bitmap functions. The patch has been tested with
a non-deterministic test case posted on the bug report.
include/my_bit.h:
Removed my_count_bits_ushort() which is not needed anymore.
Added my_count_bits_uint32().
unittest/mysys/bitmap-t.c:
Extended test coverage of my_bitmap.
Remove wrappers around inline -- static inline is used without
wrappers throughout the source code. We rely on the compiler or
linker to eliminate unused static functions.

On recent Mac OS X, fcntl(F_FULLFSYNC) is recommended over fsync()

my_sync_dir(): to sync a directory after a file creation/deletion/
renaming; can be called directly or via MY_SYNC_DIR in my_create/
my_delete/my_rename(). No-op except on Linux (see "man fsync" on Linux).
my_sync_dir_from_file(): same as above, just more practical when the
caller has a file name but no directory name ready.
