unknown 85213f6235 Fix for server bug experienced in Maria (wrong "Truncated incorrect <var_name>
value" error even though the value was correct): a C function in my_getopt.c
was taking bool* in parameter and was called from C++ sql_plugin.cc,
but on some Mac OS X sizeof(bool) is 1 in C and 4 in C++, giving funny
mismatches. Fixed, all other occurences of bool in C are removed, future
ones are blocked by a "C-bool-catcher" in my_global.h (use my_bool).


client/mysqldump.c:
  my_bool for C
client/mysqltest.c:
  my_bool for C
extra/replace.c:
  my_bool for C
include/my_getopt.h:
  my_bool for C
include/my_global.h:
  Prevent people from using bool in C, it causes real bugs.
include/my_sys.h:
  my_bool for C
include/my_time.h:
  my_bool for C
include/thr_lock.h:
  my_bool for C

mysys/my_getopt.c:
  my_bool for C
mysys/queues.c:
  my_bool for C
mysys/thr_lock.c:
  my_bool for C
regex/reginit.c:
  my_bool for C
sql/set_var.cc:
  C functions use my_bool so we must use my_bool too.
sql/sql_plugin.cc:
  C functions use my_bool so we must use my_bool too.
  This fixes a real observed bug of Maria, because on some Mac OS X,
  sizeof(bool) is 1 in C and 4 in C++, so the bool* does wrong.
  Removing useless line.
