bzr push into mysql-5.5 branch (marko.makela:3697 to 3699)

 3699 Marko Mäkelä	2012-02-02
      ha_innobase::records_in_range(): Remove a debug assertion
      that prohibits an open range (full table).
      This assertion catches unnecessary calls to this method, but such calls
      are not harming correctness.

      Bug #13651627 Move ut_ad(0) from the beginning to the end of buf_page_print(),
      print page dump
      
      buf_page_print(): Remove the ut_ad(0) from the beginning. Add two flags
      (enum buf_page_print_flags) that can be bitwise-ORed together:
      
      BUF_PAGE_PRINT_NO_CRASH:
        Do not crash debug builds at the end of buf_page_print().
      BUF_PAGE_PRINT_NO_FULL:
        Do not print the full page dump. This can be useful when adding
        diagnostic printout to flushing or to the doublewrite buffer.
      
      trx_sys_doublewrite_init_or_restore_page(): Replace exit(1) with ut_error,
      so that we can get a core dump if this extraordinary condition happens.
