POSIX requires that a signal handler defined with sigaction()
is not reset on delivering a signal unless SA_NODEFER or
SA_RESETHAND is set. It is therefore unnecessary to redefine
the handler on signal delivery on platforms where sigaction()
is used without those flags.

include/my_alarm.h:
  Renamed DONT_REMEMBER_SIGNAL ->
  SIGNAL_HANDLER_RESET_ON_DELIVERY.
include/my_global.h:
  Renamed DONT_REMEMBER_SIGNAL ->
  SIGNAL_HANDLER_RESET_ON_DELIVERY. The latter is now defined
  only on non-BSD platforms missing the POSIX sigaction()
  function.

mysql-test/suite/perfschema/t/no_threads-master.opt:
  Innodb will start multiple threads, which is
  not compatible with --one-thread.   Disable
  innodb to be able to run the test case.

In process of record search it is not taken into account
that inital quick->file->ref value could be inapplicable
to range interval. After proper row is found this value is
stored into the record buffer and later the record is
filtered out at condition evaluation stage.
The fix is store a refernce of found row to the handler ref field.

InnoDB came in a new version "simultanously" with the
commit.  This patch is a minor change to the new innodb
regression test suite. 

mysql_client_binlog_statement

Problem: server may read from unassigned memory performing
"wrong" BINLOG queries.

Fix: never read from unassigned memory.

The default storage engine is changed from MyISAM to
InnoDB, in all builds except for the embedded server.

In addition, the following system variables are 
changed:

  * innodb_file_per_table is enabled
  * innodb_strict_mode is enabled
  * innodb_file_format_name_update is changed
    to 'Barracuda'

The test suite is changed so that tests that do not
explicitly include the have_innodb.inc are run with
--default-storage-engine=MyISAM.  This is to ease the
transition, so that most regression tests are run
with the same engine as before.

Some tests are disabled for the embedded server
regression test, as the output of certain statements
will be different that for the regular server
(i.e SELECT @@default_storage_engine).  This is to
ease transition.



mysql-test/mysql-test-run.pl:
  The regression test suite now adds a
  --default-storage-engine=MyISAM for all non-innodb 
  tests.  This behaviour can be controlled by the
  default-myisam switch in mysql-test-run
mysql-test/t/bootstrap-master.opt:
  The bootstrap test can only be run without InnoDB
  as it starts several mysqld instances on the same
  datadir. This is possible with MyISAM, but not
  with InnoDB.

Incremental patch to fix plugin_dir from .../lib/plugin to .../lib/mysql/plugin.

TABLE_SHARE a class.

Remove unused members in TABLE_SHARE.

This is the fix for 5.5, where the behaviour on both installation
and upgrade is changed:
On installation, we do not start the server, to allow automated
installs (which happen in some indeterminate machine status).
If the server was stopped when the upgrade begins, we assume the
administrator is taking manual action, so we do not start the (new)
server at the end of the upgrade.
We still install the start/stop script, so it will be started on reboot.


support-files/mysql.spec.sh:
  In the "pre" section of the spec file, check the server status, and write
  the result to a file.
  In the "post" section, evaluate the status file, and start the server if
  it was running during status analysis.
  In 5.5, we do *not* start the server if there is no status file (which will happen on first installation, when there is no data directory yet).

This is the fix for 5.1, where only the behaviour on upgrade is changed:
If the server was stopped when the upgrade begins, we assume the
administrator is taking manual action, so we do not start the (new)
server at the end of the upgrade.
We still install the start/stop script, so it will be started on reboot.

On [Open]Solaris/x86 the FPU was not switched to 64-bit double
precision mode when the server binary was built with Sun
Studio. That caused GIS test failures due to differences in
expected and actual results.
