Fixed compilation problem on windows.


configure.cmake:
  Added test for pthread_attr_getguardsize
include/my_stacktrace.h:
  Define dummy my_init_stacktrace() to allow one to call it without #ifdef HAVE_STACKTRACE
sql/mysqld.cc:
  Move my_setstacksize() to fix compilation problem on windows
  Don't disable core on signal just becasue platform doesn't handle stack trace

Fixed failing tests in sys_vars as we have now stricter checking of setting of variables.

mysys/my_getsystime.c:
  Merge + fixed bug that __NR_clock_gettime didn't work in 5.5

Added a --nowatch (with aliases --no-watch and --no-auto-restart) option to mysqld_safe that causes it to exit after
spawning mysqld.  We don't need mysqld_safe to restart mysqld after a crash, because systemd can do that just fine.

Based on code from Maarten Vanraes

scripts/mysqld_safe.sh:
  Added option --nowatch (with aliases --no-watch and --no-auto-restart)

Thanks to Maarten Vanraes for the patch


sql/sql_plugin.cc:
  Fix plugin boolean variables to receive the value "1", not "-1", when they are set to 1.
  Aside from being bizarre, the existing behavior is unportable: machines where char is unsigned print "255" instead.

2. my_new.cc should redefine new (std:nothrow) too.

Fixed that repair removes the 'table is moved' mark.

new make target - abi_update

libservices/HOWTO:
  remove references to Makefile.am
  small tweaks

The issue was that check/optimize/anaylze did not zerofill the table before they started to work on it.
Added one more element to not often used function handler::auto_repair() to allow handler to decide when to auto repair.

bug in semisync plugin. It didn't check thd->killed before waiting on mysys->current_cond,
and thus an attepmt to kill the thread (on shutdown) was lost

Added feature request 'reading of my.cnf files' to mytop
Thanks to Jean Weisbuch for the patch/suggestion.


scripts/mytop.sh:
  Added feature request from lp:956585 "Feature request - prevent truncating query in mytop"
  Added feature request 'reading of my.cnf files'

- This is a regession introduced by fix for BUG#951937
- The problem was that there were scenarios where check_simple_equality() would create an
  Item_equal object but would not call item_equal->set_context_field() on it. 
- The fix was to add the missing calls.
