Release all event semaphores at shutdown also in Windows
srv0start.c, srv0srv.c:
make test sometimes failed because lock timeout thread exited without decrementing the InnoDB thread counter
Let InnoDB to skip writing of pages from the doublewrite buffer if innodb_force_recovery=6; normally, if the page is corrupt AND the corresponding page in the doublewrite buffer is also corrupt, InnoDB calls exit(1)
Clean up the working of the main thread; add a tunable parameter srv_max_buf_pool_modified_pct which can be used to make the flush phase in shutdown quicker

libraries always ended up in "dir..", even though they were not supposed
to be installed anyway (they are only required at link time). Fixed it by
replacing libs_LIBRARIES with noinst_LIBRARIES for all InnoDB Makefile.am
files and by removing "libsdir = " from innobase/include/Makefile.i .
Call pthread_mutex_destroy() on not used mutex.
Changed comments in .h and .c files from // -> /* */
Added detection of mutex on which one didn't call pthread_mutex_destroy()
Fixed bug in create_tmp_field() which causes a memory overrun in queries that uses "ORDER BY constant_expression"
Added optimisation for ORDER BY NULL
Merge InnoDB-4.0.7. Support for ON UPDATE CASCADE
sql_select.cc:
Remove superfluous prints to .err log when a locking SELECT fails to a deadlock or a lock wait timeout
Fix hang introduced by selective deadlock resolution
srv0srv.c, row0mysql.c:
Fix hang introduced by selective deadlock resolution + corruption caused by lock timeout or sel deadl res in ON DELETE CASCADE
Merge InnoDB-4.0.5: new isolation levels READ COMMITTED and READ UNCOMMITTED now supported, selective deadlock resolution
mysqld.cc:
Change MySQL default isolation level to REPEATABLE READ; note that InnoDB has always had that default, and BDB and MyISAM always run at SERIALIZABLE level anyway
Change srv_flush_log_at_trx_commit to ulint, note that ibool is defined as ulint, so this is purely formal change
os0file.c:
Start using unbuffered i/o again in Windows because sequential read using normal i/o was 4 times slower in XP
Redefine sprintf as ut_sprintf inside InnoDB code; some old Unixes may have a pointer as the return type of sprintf
lock0lock.c:
Add safety against buffer overruns in latest deadlock info
srv0srv.c:
Add safety against buffer overruns in SHOW INNODB STATUS
os0thread.h, os0thread.c:
Fix a portability bug introduced in Windows when we changed os_thread_id_t to be the same as os_thread_t
