We introduce a new function mysql_test_parse_for_slave().
If the slave sees that the query got a really bad error on master
(killed e.g.), then it calls this function to know if this query
can be ignored because of replicate-*-table rules (do not worry
about replicate-*-db rules: they are checked so early that they have
no bug). If the answer is yes, it skips the query and continues. If
it's no, then it stops and say "fix your slave data manually" (like it
did before this change).

re-using unused LOCK_active_mi to serialize all administrative
commands related to replication:
START SLAVE, STOP SLAVE, RESET SLAVE, CHANGE MASTER, init_slave()
(replication autostart at server startup), end_slave() (replication
autostop at server shutdown), LOAD DATA FROM MASTER.
This protects us against a handful of deadlocks (like BUG#2921
when two START SLAVE, but when two STOP SLAVE too).
Removing unused variables.

  Print always the count of pending pread() and pwrite() calls if there is a long semaphore wait

  Do not test a magic number with =, use == instead :)

added tests for testing structure of mysql db

ChangeSet 1.1620.12.1 and ChangeSet 1.1625.2.1
from 4.1. This makes the slave I/O thread flush the relay log 
after every event, which provides additional safety in case
of brutal crash (reduces chances to lose a part of the relay log).

- the one about BUG#2921
- the one about relay log flushing
Both will be rewritten in a next changeset
(this one will not be pushed before the next changeset).

  Add typecasts to ulong because ulint is __int64 in Win 64-bits
  Better error message to the .err log if we have to crash the server because the buffer pool is exhausted by the lock table or the adaptive hash index

INSERT DELAYED works only for one-row inserts (in latest 4.0 versions
at least). So killing a delayed_insert thread does not spoil replication:
the rows which actually went into the table are exactly those listed
in the binlog. So when the delayed_insert thread is killed, don't log
it as 'killed', because it causes superfluous stops on the slave.

Allow one to force lower_case_table_names to 0, even if the file system is case insensitive. This fixes some issues on Mac OS X (Bug #2994)
Added variables "lower_case_file_system", "version_compile_os" and "license"

Setting insert delayed threads = 0 at mysql_init_command.

even if the thread was killed, we write the DROP with error_code=0.
This will remove unneeded stops on slave, and will lose nothing:
if a real update was killed, this real update will be logged with the
nonzero error code and will cause the stop on slave.
