      WL#8354 BACKPORT DIGEST IMPROVEMENTS TO MYSQL 5.6

(with the following commits) and related changes in sql/

(See MDEV-7440 Build fails in libgroonga on Solaris)

MDEV-8082 ON UPDATE is not preserved by CREATE TABLE .. SELECT

and remove duplicates

-LONGLONG_MIN is the undefined behavior in C.
longlong2decimal() used to do this:

  int longlong2decimal(longlong from, decimal_t *to) {
    if ((to->sign= from < 0))
      return ull2dec(-from, to);
    return ull2dec(from, to);

and later in ull2dec() (DIG_BASE is 1000000000):

  static int ull2dec(ulonglong from, decimal_t *to) {
    for (intg1=1; from >= DIG_BASE; intg1++, from/=DIG_BASE) {}

this breaks in gcc-5 at -O3. Here ull2dec is inlined into
longlong2decimal. And gcc-5 believes that 'from' in the
inlined ull2dec is always a positive integer (indeed, if it was
negative, then -from was used instead). So gcc-5 uses
*signed* comparison with DIG_BASE.

Fix: make a special case for LONGLONG_MIN, don't negate it

MDEV-8045 Assertion `0' fails in Protocol::end_statement on CREATE VIEW after another connection aborted

0 is a valid value for a file descriptor

On EOF vio_read returns 0, it's not an error so the errno
is not reset. If the previous error was EINTR the client
will loop forever. See also man recv.
