  Visual C++ apparently does not know what -1LL (= -1 in longlong type) means

  Fix Visual C++ compilation errors reported by Miguel

comment clarified

  IMPORT TABLESPACE must reset lsns if they are too high
ha_innodb.cc:
  DISCARD/IMPORT TABLESPACE must have a TL_WRITE lock on the table

  Add DISCARD etc. in the keyword: rule of sql_yacc.yy
sql_table.cc:
  Add comment that DISCARD/IMPORT TABLESPACE is always the only clause in an ALTER TABLE

typo in error message text corrected.
new tests added

(BUG#1537)

  Fix error in --show-slave-auth-info help string.

I manually edited rpl_openssl.result because the test is skipped on my
machine. Hope it's correct.

a better comment, and replacing an assignment by an equivalent simpler one.

  Add Stefan's new translations.

"Add a column "Timestamp_of_last_master_event_executed" in SHOW SLAVE STATUS".
Finally this is adding
- Slave_IO_State (a copy of the State column of SHOW PROCESSLIST for the I/O thread,
so that the users, most of the time, has enough info with only SHOW SLAVE STATUS).
- Seconds_behind_master. When the slave connects to the master it does SELECT UNIX_TIMESTAMP()
on the master, computes the absolute difference between the master's and the slave's clock.
It records the timestamp of the last event executed by the SQL thread, and does a
small computation to find the number of seconds by which the slave is late.
