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));

as it fails on new builders.

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.

- Fixed wrong argument to pthread_mutex in server_audit.c when compiling with debug
- Adding missing debug_sync_update() to debug_sync.h
- Added initializers to some variables and fixed error handling in jsonudf.cpp
- Fixed cluster_filter_unpack_varchar which doesn't have a stable index type.
- Updated compiler_warnings.supp

- Add more tests to the mysql_index.test file

- Fix and error causing remote indexing to fail when for not unique index.
  Was experienced with MYSQL, ODBC and JDBC tables.

- Fix MDEV-9966 (zero lines returned)

Fixed wait condition to wait for InnoDB to actually acquire row locks instead
of waiting for thread to enter "Searching rows for update" state (which happens
earlier).

Also use default wait timeout, 2 seconds can be too few for threads to enter
appropriate state.

Spider:
  SunPro only supports array declarations with
  constant size. Spider already has a workaround for
  that, inside #ifdef _MSC_VER. Enable this code
  also for __SUNPRO_CC

Connect:
  Don't use anonymous union.
  Cast for mmap.
  Don't pass gcc-ish -W... options to SunPro

This fixes:
