- Fix bug in bootstrapper. 

- Also, delete innodb log files cafter bootstrapping , to workaround
"different log size" Innodb error during the first service start by MSI. 
This is a temporary measure, in the future innodb will allow handling 
different file size more gracefully.

The reason for the error is missing definition for SIGNAL_WITH_IO_CLOSE on this platform
which now needs to  always be defined, as in 5.6

On Solaris10 only, this preprocessor constant was not defined,  thus code that shutdowns a socket in THD::awake was not executed, and polling thread was not interrupted.

Fix is to always define SIGNAL_WITH_IO_CLOSE, just like MySQL5.6 does.

Improve cleanup in create_initial_db.cmake,  fix the 'table already exists' error if build is run twice.

Fix mismerged code from 5.6 (named-pipe related).  viopipe.c, which was introduced in 5.6  is now copied almost identically into 10.0 

The unused vio::pipe_overlapped is removed.

and related fixes from: BUG#1006164, MDEV-376:

Now, ROR-merged QUICK_RANGE_SELECT objects make no assumptions about the values
of table->read_set and table->write_set.
Each QUICK_ROR_SELECT has (and had before) its own column bitmap, but now, all 
QUICK_ROR_SELECT's functions that care: reset(), init_ror_merged_scan(), and 
get_next()  will set table->read_set when invoked and restore it back to what 
it was before the call before they return.

This allows to avoid the mess when somebody else modifies table->read_set for 
some reason.

Use post_kill_notification in for one_thread_per_connection scheduler, 
the same as already used in threadpool, to reliably wake a thread  stuck in 
read() or in different poll() variations.

 - Ensure asm parameters are in registers, so we do not de-reference from
   bogus stack pointer.

 - Make return address undefined in DWARF unwind info in my_context_spawn,
   so DWARF-based unwinders will know this is the end of the call stack
   (same as the amd64 fix for the similar issue).

Disable compiling unit tests if WITH_UNIT_TEST is FALSE.

Also, fix CMake code to allow compilation WITHOUT_ARIA_STORAGE_ENGINE

and when safemalloc is enabled (use ucontext, otherwise backtrace function gets confused and crashes)

Changed implementation os_file_rename() on Windows  such as it does not fail if destination file already exists. Now MoveFileEx() with MOVEFILE_REPLACE_EXISTING flag is used, instead of prior MoveFile().
This fixed implementation is better compatible with rename() on POSIX systems.

because it assumes the function prologue that gcc does not
generate.

Ensure semicolons are not lost when concatenating fill_help_tables to  bootstrap.sql in Windows.
5.6 bootstrapper requires semicolons to separate bootstrapper commands.

  always use intptr type when casting a pointer to an integer to avoid sign expansion.
  or, at least, cast identically in socket_summary_by_instance and socket_instances

The following piece of code in trnman.c:

345   trn->min_read_from=  active_list_min.next->trid;
  ...
351   active_list_max.prev= trn->prev->next= trn;
352   trid_min_read_from= active_list_min.next->min_read_from;

on 345 gcc stores active_list_min.next in %ebx
(and trn->min_read_from=[%ebx]->trid)
and on 352 it does trid_min_read_from= [%ebx]->min_read_from;
BUT active_list_min.next was changed on the line 351.
gcc doesn't notice it and continues to use the cached value.

This patch undoes the removal of enum store_key_result by the previous patch for mdev-3812.

(because of a width or a short buffer)

MDEV-3812: Remove unneeded extra call to engine->exec() in Item_subselect::exec, remove enum store_key_result

This task fixes an ineffeciency that is a remainder from MySQL 5.0/5.1. There, subqueries
were optimized in a lazy manner, when executed for the first time. During this lazy optimization
it may happen that the server finds a more efficient subquery engine, and substitute the current
engine of the query being executed with the new engine. This required re-execution of the engine.

MariaDB 5.3 pre-optimizes subqueries in almost all cases, and the engine is chosen in most cases,
except when subquery materialization found that it must use partial matching. In this case, the
current code was performing one extra re-execution although it was not needed at all. The patch
performs the re-execution only if the engine was changed while executing.

In addition the patch performs small cleanup by removing "enum store_key_result" because it is
essentially a boolean, and the code that uses it already maps it to a boolean.

Adjusted test case results after the merge 10.0-base, 10.0-monty.
The results are in sync with MySQL 5.6.7.

fix rpl_mdev382.result

do not print return address when callstack is output on Windows, it does not provide any useful info
