server to crash".

Crash caused by assertion failure happened when one ran SHOW OPEN TABLES
while concurrently doing DROP TABLE (or RENAME TABLE, CREATE TABLE LIKE
or any other command that takes name-lock) in other connection.
For non-debug version of server problem exposed itself as wrong output
of SHOW OPEN TABLES statement (it was missing name-locked tables).
Finally in 5.1 both debug and non-debug versions simply crashed in
this situation due to NULL-pointer dereference.

This problem was caused by the fact that table placeholders which were
added to table cache in order to obtain name-lock had TABLE_SHARE::table_name
set to 0. Therefore they broke assumption that this member is non-0 for
all tables in table cache which was checked by assert in list_open_tables()
(in 5.1 this function simply relies on it).
The fix simply sets this member for such placeholders to appropriate value
making this assumption true again.

This patch also includes test for similar bug 12212 "Crash that happens
during removing of database name from cache" reappeared in 5.1 as bug 19403.


mysql-test/r/drop.result:
  Added test for bug#21216 "Simultaneous DROP TABLE and SHOW OPEN TABLES
  causes server to crash" and bug#12212/19403 "Crash that happens during
  removing of database name from cache".
mysql-test/t/drop.test:
  Added test for bug#21216 "Simultaneous DROP TABLE and SHOW OPEN TABLES
  causes server to crash" and bug#12212/19403 "Crash that happens during
  removing of database name from cache".
sql/lock.cc:
  lock_table_name():
    Our code assumes that TABLE_SHARE::table_name for objects in table cache
    is non-NULL (for example look at assertion in list_open_tables()). This
    was not true for table placeholders that were added to table cache for
    name-locking. So let us set this member for such placeholders.

The problem was that the grammar allows to create a function with an optional
definer clause, and define it as a UDF with the SONAME keyword.
Such combination should be reported as an error.

The solution is to not change the grammar itself, and to introduce a
specific check in the yacc actions in 'create_function_tail' for UDF,
that now reports ER_WRONG_USAGE when using both DEFINER and SONAME.

  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 
  algorithm. This means that if they are not specified in ALTER VIEW
  their values are preserved from CREATE VIEW instead of being defaulted.
