If a view was created with the DEFINER security and later the definer user
was dropped then a SELECT from the view throws the error message saying that
there is no definer user is registered. This is ok for a root but too much
for a mere user.

Now the st_table_list::prepare_view_securety_context() function reveals
the absence of the definer only to a superuser and throws the 'access denied'
error to others.

mending windows test.

The regression is caused by the fix for bug 14767. When INSERT ... SELECT
used a view in the SELECT list that was not inlined, and there was an 
active transaction, the server could crash in Query_cache::invalidate.

On INSERT ... SELECT only the table being inserted into is invalidated.
Thus views that can't be inlined are skipped from invalidation.

The bug manifests itself in two ways so there is 2 test cases.
One checks that the only the table being inserted into is invalidated.
And the second one checks that there is no crash on INSERT ... SELECT.

 The server sends a number of columns to the client.
 It uses a limited "fast" function for that instead of the
 general one. This fast function cannot send numbers larger 
 than 2 bytes. 
 This causes the client to expect smaller number of columns. 
 The client writes outside of the allocated memory buffer 
 as a result.
 Fixed the server to use the general function to send column
 count.
 Fixed the client to check the column count before writing
 column data. 

comments are fixed as was suggested in reviews.

bugs/wls in cset's comments. The targetted BUG's or WL's identifier must be specified
the first in the comments. The referred bugs wls can be typed in same as the targeted
clickable format.
If the the target of the fix is a WL and there are some references to bugs
then the first found reference is regarded as "co-target" so that the bug's identifier
comes up on the subject line along with the WL's and commit mail will update
the bug page. The latter feature can be disarmed (if there is no need to update
the referred bug's page) with typing the first a pseudo-bug pattern (bug#0).

This paticular cset will generate subject line containing bug#0 (as it was the first
referred) whereas the old version would put in the subject line the last referred
pattern (e.g bug#2147483648).
