HP-UX compiler was generating code which makes wrong conversion from double to
ulonglong which results in not using index in some cases.

Changed type cast operators odrer with which generated code makes proper 
conversion.

subqry order by server crash": failing DBUG_ASSERT(curr_join == this)
when opening a cursor.
Ensure that for top-level join curr_join == join (always), 
and thus fix the failing assert.
curr_join is a hack to ensure that uncacheable subqueries can be
re-evaluated safely, and should be never different from main join
in case of top-level join.

We should not allow FLUSH statement to be executed inside both triggers
and stored functions.

str_alloc had been added but was not added to mysqlclient and strings
libmysql should have had strings as a dependent.

When PRIMARY KEY is present ha_innobase::cmp_ref() uses it to compare refs.
After comparing part of key it moves pointers to compare next part.
For varchar parts pointers were moved only by length of parts, not including
bytes containig part length itself. This results in wrong comparision and
wrong number of deleted records.

* Cleanup SP Cache code, now SP Cache only deletes sp_head objects in 
  sp_cache_flush_obsolete() invalidates all pointers to routines in the cache.
* Use new SP Cache use contract in the code.

There is no test case because it doesn't seem to be possible to cause thread races to end
the same way they end in heavy-load test. This patch removes the crash in heavy test.

  Add a forgotten newline to a print
