Fixed memory leak when mroonga fails to open index files.
Memory leak was detected by valgrind when running
mroonga/storage.repair_table_no_index_file.

metadata_lock_info plugin called MDL_context::find_ticket() to obtain lock
duration, which in turn iterates foreign thread private lists. These lists
can be updated by owner thread without protection.

Fixed by iterating threads (instead of MDL locks and tickets) and obtaining
data through APC.

Also fixed mdl_iterate_lock() to initialize iterator under prlock protection.

"result" may be uninitialized when json_set_item() is called directly.

Analysis: In storage/innobase/row/row0merge.cc InnoDB calls
thd_progress_init, thd_progress_report and thd_progress_end
functions. These seem to cause crash on solaris 10 64-bit.

Fix: Disable progress reporting on UNIV_SOLARIS until the
actual issue causing the crash is fixed. The actual bug
is not on InnoDB code base.

disable innodb on sol10-64

because buildbot config invokes BUILD/compile-solaris-amd64
with the --extra-args=--without-plugin-innodb argument, but
BUILD/compile-solaris-amd64 doesn't take arguments and doesn't
invoke configure.pl, so this extra-args is lost.

The problem was that the loop in get_func_mm_tree()
accessed improperly initialized instances of String,
which resided in the bzero'ed part of the in_vector::base array.

Strings in in_vector::base are originally initialized
in Item_func_in::fix_length_and_dec(),
in in_vector::in_vector() using sql_calloc,
rather than using a String constructor, so their str_charset
members are originally equal to NULL.

Strings in in_vector::base are later initialized
to good values in Item_func_in::fix_length_and_dec(),
using array->set(), in this code:

      uint j=0;
      for (uint i=1 ; i < arg_count ; i++)
      {
        array->set(j,args[i]);
        if (!args[i]->null_value)                      // Skip NULL values
          j++;
        else
          have_null= 1;
      }
      if ((array->used_count= j))
        array->sort();

NULLs are not taken into account, so at the end
array->used_count can be smaller than array->count.

This patch fixes the loop in opt_range.cc, in get_func_mm_tree(),
to access only properly initialized elements in in_vector::base,
preventing access to its bzero'ed non-initialized tail.

item when drop table indexes or drop table;

Problem was that table and index statistics is removed from
persistent tables but not from memory cache. Added functions
to remove table and index statistics from memory cache.

        test failed on Windows so fixed by testing slightly differently.

The problem was earlier fixed by the patch for MDEV-9521.
Adding tests only.

        Changes to the mysql_install_db scripts so they don't repeat
        arguments twice.

        Check for same directories in the list added.

The check inserts a DWARF directive to tell stack unwinding that the
bottom of the (co-routine) stack has been reached. Without this, stack
traces may attempt to continue past the bottom of the stack.

The GCC version check was incorrect, and failed to trigger for GCC
version 5.[0123].

MDEV-10118 : do not suggest upgrade from MySQL 5.7 to MariaDB 10.x in the installer. Do not lauch upgrade wizard after installation

Clang warns on this code because it is memsetting over a vtable contained in a
struct in the best_positions array. The diagnostic text is:

mariadb/sql/sql_select.cc:24462:10: error: destination for this 'memset' call is
a pointer to class containing a dynamic class 'Duplicate_weedout_picker'; vtable
pointer will be overwritten [-Werror,-Wdynamic-class-memaccess]
  memset(best_positions, 0, sizeof(POSITION) * (table_count + 1));

msxml6 is found on all Windows we support, thus there is no reason to
search for it.

in case of prelocking, don't check table->grant.privilege
in handler::external_lock(), do it in
handler::start_stmt().

Fixed memory leaks in gen_lex_hash.

take into account that agg_arg_charsets_for_comparison()
can replace Item_field's with Item_func_conv_charset

        Added SSL support to the mysqlbinlog.

Problem was that notify_shared_lock() didn't abort an insert delayed thread
if it was in thr_upgrade_write_delay_lock().

ALTER TABLE first takes a weak_mdl_lock, then a thr_lock and then tries to upgrade
the mdl_lock.
Delayed insert thread first takes a mdl lock followed by a
thr_upgrade_write_delay_lock()
This caused insert delay to wait for alter table in thr_lock, while
alter table was waiting for the mdl lock by insert delay.

Fixed by telling mdl to run thr_lock_abort() for the insert delay thread table.
We also set thd->mysys_var->abort to 1 for the delay thread when it's killed
by alter table to ensure it doesn't ever get locked in thr_lock.
