      Bug #38883 (reopened): thd_security_context is not thread safe, crashes?

      The bug 38816 changed the lock that protects THD::query from
      LOCK_thread_count to LOCK_thd_data, but didn't update the associated
      InnoDB functions.

      1. The innobase_mysql_prepare_print_arbitrary_thd and the
      innobase_mysql_end_print_arbitrary_thd InnoDB functions have been
      removed, since now we have a per-thread mutex: now we don't need to wrap
      several inter-thread access tries to THD::query with a single global
      LOCK_thread_count lock, so we can simplify the code.

      2. The innobase_mysql_print_thd function has been modified to lock
      LOCK_thd_data in direct way.

Revert a change that was accidentally committed in r6345.

debug assertion ut_ad(len > 0) with ut_ad(len >= OS_FILE_LOG_BLOCK_SIZE).

This change is only for readability, for Issue #428.  Another
assertion on len being an integer multiple of OS_FILE_LOG_BLOCK_SIZE
already ensured together with the old ut_ad(len > 0) that actually len
must be at least OS_FILE_LOG_BLOCK_SIZE.

accidentally added in r1591, which introduced dfield_t::ext in order
to make the merge sort of fast index creation support externally
stored columns.

Initially, I tried to allocate the bit for dfield_t::ext from
dfield_t::len by making the length 31 bits and mapping UNIV_SQL_NULL
to something that would fit in it.  Then I decided that it would be
too risky.  The redundant check was part of the mapping.  The
condition may have been dfield_is_null() initially.

This is similar to the redundant code in row_sel_fetch_columns() that
was noticed by Sergey Petrunya on the MySQL internals list and removed
in r6285.  As far as I can tell, there are no redundant UNIV_SQL_NULL
assignments remaining after this change.
