unknown 39defccfd4 Fixing BUG#17719 "Delete of binlog files fails on Windows" ...

and BUG#19208 "Test 'rpl000017' hangs on Windows".
 Both bugs are caused by attempting to delete an opened
 file and to create immediatedly a new one with the same
 name. On Windows it can be supported only on NT-platforms
 (by using FILE_SHARE_DELETE mode and with renaming the
 file before deletion). Because deleting not-closed files
 is not supported on all platforms (e.g. Win 98|ME) this
 is to be considered harmful and should be eliminated by
 a "code redesign".


VC++Files/mysys/mysys.vcproj:
  To be sure that __NT__ is defined for Win configurations.
   Temporary, to be changed in more appropriate way.
include/my_sys.h:
  Adding my_delete_allow_opened to be invoked to delete
   a (possibly) not closed file on Windows NT-platforms.
mysys/my_delete.c:
  Adding nt_share_delete() function implementing
   a (possibly) not closed file deletion on Windows NT.
sql/log.cc:
  MYSQL_LOG::reset_logs(): Deleting usually not
   closed binlog files.
