- Fix MDEV-7935 by suppressing error resetting code in delete_or_rename_table.
  However, the issue is that this code was added because without it an assertion
  was raised in some cases. Unfortunately I can't remember what were these cases.
  Therefore fixing it in this case will perhaps make a new crash happening on another cases.

- Add the UDF Json_Array_Delete.

  jsonudf.cpp

in when using vio->read_timeout (and write_timeout) to set
timeouts of a new vio, as in:

  vio_timeout(vio, 0, old_vio.read_timeout)
  vio_timeout(vio, 0, old_vio.write_timeout)

remember that timeouts are stored in ms, but vio_timeout()'s
argument is in seconds.

Gave priority to password field when using a native authentication
plugin.

Also, prevented a user from setting an invalid auth_string, when using
native authentication.

specify RECOMPILE_FOR_EMBEDDED and disable tests in suite.pm

      WL#8354 BACKPORT DIGEST IMPROVEMENTS TO MYSQL 5.6

(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.
