Support of CLIENT_REMEMBER_OPTIONS and freeing options added.

Update contributors

Resultsets which contain more than one row need to be sorted

        Temporary tables support added for RENAME and ALTER TABLE.

don't call strlen() in the loop

a test case for a broken vcols behavior with different
charsets. this is fixed in 10.2

MDEV-10211 : fix ssl test not to use specific value of ssl_cipher, as it can change between different openssl/yassl version

add a test case

Addreses are not necessarily between heap_start && heap_end. Malloc
calls using mmap can place pointers outside these bounds. In this case,
we'll warn the user that the query pointer is potentially invalid.
However, we'll attempt to print the data anyway after we're done
printing everything else.

MDEV-10318 : Fix crash in embedded, in case prepared statement has parameter placeholders, but does not bind parameters

-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

innodb_shutdown_for_mysql in ppc64el on test
case innodb_fts.innodb_fts_stopword_charset.

State column of SHOW PROCESSLIST can have NULL values for being initialized
threads (between new connection was acknowledged and waiting for network data).

Fixed test case to handle such cases by waiting for State to become empty
string.

thd should not be taken earlier then fix_field and reset on fix_fields if it is needed.

Disable output of MDL lock duration since there is no facility to retreive
it properly.

Reverted APC based fix. APC subsystem is not ready to serve metadata_lock_info
needs.

    MDEV-10083: Orphan ibd file when playing with foreign keys

    Analysis: row_drop_table_for_mysql did not allow dropping
    referenced table even in case when actual creating of the
    referenced table was not successfull if foreign_key_checks=1.

    Fix: Allow dropping referenced table even if foreign_key_checks=1
    if actual table create returned error.

windows: use GetProcAddress() to access internal server data structures
rhel5: CONNECT-JDBC requires at least Java 1.6

This used to be a compile failure. The defined structure isn't required
in the later versions of boost.

Fix the replication failure caused by incorect initialization of
THD::invoker_host && THD::invoker_user.

Breakdown of the failure is this:
Query_log_event::host and Query_log_event::user can have their
LEX_STRING's set to length 0, but the actual str member points to
garbage. Code afterwards copies Query_log_event::host and user to
THD::invoker_host and THD::invoker_user.

Calling code for these members expects both members to be initialized.
Eg. the str member be a NULL terminated string and length have
appropriate size.

The bug is apparent when the username is longer than the rolename.
It is caused by a simple typo that caused a memcmp call to compare a
different number of bytes than necessary.

The fix was proposed by Igor Pashev. I have reviewed it and it is the
correct approach. Test case introduced by me, using the details provided
in the MDEV.

disable unstable tokudb tests,
(old change that was lost in a merge)

1. remove unnecessary rpl-tokudb combination file.
2. fix rpl_ignore_table to cleanup properly (not leave test
   grants in memory)
3. check_temp_dir() is supposed to set the error in stmt_da - do
   it even when called multiple times, this fixes a crash when
   rpl.rpl_slave_load_tmpdir_not_exist is run twice.

fix constants to stay 64-bit instead of being truncated by VS.
this fixes a hang on startup.

in particular, revert changes to the spider (avoid diverging from
  the upstream if possible)

Added missing target_thd initialization when processing local thread.

The patch fixes the problem with loading information from system tables
(e.g. event and help related tables) when PAD_CHAR_TO_FULL_LENGTH is enabled,
as well as includes some additional minor improvements:
- refactoring in get_field() to return an error rather than success
  if strmake_root() failed
- removing of duplicate code in similar functions:
  char *get_field(MEM_ROOT *mem, Field *field)
  bool get_field(MEM_ROOT *mem, Field *field, String *res)
