When a view was used inside a trigger or a function, lock type for
tables used in a view was always set to READ (thus making the view
non-updatable), even if we were trying to update the view.
The solution is to set lock type properly.

Add result for bug#17591: Updatable view not possible with trigger
or stored function.
mysql-test/t/view.test:

sql/sql_view.cc:
Move the code that sets requested lock type before the point where
we exit from mysql_make_view() when we process a placeholder for
prelocked table.

User name (host name) has limit on length. The server code relies on these
limits when storing the names. The problem was that sometimes these limits
were not checked properly, so that could lead to buffer overflow.
The fix is to check length of user/host name in parser and if string is too
long, throw an error.

SELECT right instead of INSERT right was required for an insert into to a view.
This wrong behaviour appeared after the fix for bug #20989. Its intention was
to ask only SELECT right for all tables except the very first for a complex
INSERT query. But that patch has done it in a wrong way and lead to asking
a wrong access right for an insert into a view.
The setup_tables_and_check_access() function now accepts two want_access
parameters. One will be used for the first table and the second for other
tables.

This bug is a side-effect of bug fix#16377. NOW() is optimized in
BETWEEN to integer constants to speed up query execution. When view is being
created it saves already modified query and thus becomes wrong.
The agg_cmp_type() function now substitutes constant result DATE/TIME functions
for their results only if the current query isn't CREATE VIEW or SHOW CREATE
VIEW.

When executing ALTER TABLE all the attributes of the view were overwritten.
This is contrary to the user's expectations.
So some of the view attributes are preserved now : namely security and

their values are preserved from CREATE VIEW instead of being defaulted.
