Another problem is that the backtrace facility wasn't being
enabled for non-Linux targets even if the target OS has the
backtrace functions. Also, the stacktrace functions inside
mysqltest were being used without proper checks for their
presence in the build.

                  replicated correctly between machines with
                  mixed endiannes

The problem was that when a embedded linked version of mysqltest
crashed there was no way to obtain a stack trace if no core file
is available. Another problem is that the embedded version of
libmysql was not behaving (crash) the same as the non-embedded with
respect to sending commands to a explicitly closed connection.

The solution is to generate a mysqltest's stack trace on crash
and to enable "reconnect" if the connection handle was explicitly
closed so the behavior matches the non-embedded one.

The problem was that when comparing tables for a possible
fast alter table, the comparison was being performed using
the parsed information and not the final definition.
      
The solution is to use the possible final table layout to
compare if a fast alter is possible or not.

           if cached query uses many tables

The problem was that query cache would not properly cache
queries which used 256 or more tables but yet would leave
behind query cache blocks pointing to freed (destroyed)
data. Later when invalidating (due to a truncate) query cache
would attempt to grab a lock which resided in the freed data,
leading to hangs or undefined behavior.

This was happening due to a improper return value from the
function responsible for registering the tables used in the
query (so the cache can be invalidated later if one of the
tables is modified). The function expected a return value of
type boolean (char, 8 bits) indicating success (1) or failure
(0) but the number of tables registered (unsigned int, 32 bits)
was being returned instead. This caused the function to return
failure for cases where it had actually succeed because when
a type (unsigned int) is converted to a narrower type (char),
the excess bits on the left are discarded. Thus if the 8
rightmost bits are zero, the return value will be 0 (failure).

The solution is to simply return true (1) only if the number of
registered table is greater than zero and false (0) otherwise.

  
Problem was an unclear error message since it could suggest that
MyISAM did not support INSERT DELAYED.
Changed the error message to say that DELAYED is not supported by the
table, instead of the table's storage engine.
The confusion is that a partitioned table is in somewhat sense using
the partitioning storage engine, which in turn uses the ordinary
storage engine. By saying that the table does not support DELAYED we
do not give any extra informantion about the storage engine or if it
is partitioned.

Bug 36788 Multiple funcs_1 'trig' tests are failing on vanilla builds

Fix for this bug and additional improvements/fixes
In detail:
- Remove unicode attribute from several columns
  (unicode properties were nowhere needed/tested)
  of the table tb3
  -> The runnability of these tests depends no more on
     the availibility of some optional collations.
- Use a table tb3 with the same layout for all
  engines to be tested and unify the engine name
  within the protocols.
  -> <engine>_trig_<abc>.result have the same content
- Do not load data into tb3 if these rows have no
  impact on result sets
- Add tests for NDB (they exist already in 5.1)
- "--replace_result" at various places because
  NDB variants of tests failed with "random" row
  order in results
  This fixes a till now unknown weakness within the
  funcs_1 NDB tests existing in 5.1 and 6.0
- Fix the expected result of ndb_trig_1011ext
  which suffered from Bug 32656
  + disable this test
- funcs_1 could be executed with the mysql-test-run.pl
  option "--reorder", which saves some runtime by
  optimizing server restarts.
  Runtimes on tmpfs (one attempt only):
  with    reorder 132 seconds
  without reorder 183 seconds
- Adjust two "check" statements within func_misc.test
  which were incorrect (We had one run with result set
  difference though the server worked good.)
- minor fixes in comments

The federated storage engine is now disabled by default.
mysql-test-run.pl is updated to enable it whenever it's required and available.

Upmerge of fix for this bug and a second similar problem
found during experimenting.

This replaces the first fix (already pushed to 5.1
and merged to 6.0) which
- failed in runs with the embedded server
- cannot be ported back to 5.0
