Its root cause is a difference between the "readline" and "libedit" (header files)
definitions of "rl_completion_entry_function", where the "libedit" one is wrong anyway:
This variable is used as a pointer to a function returning "char *",
but "libedit" declares it as returning "int" and then adds casts on usage.

Change it to "CPFunction *" and get rid of the casts.


client/mysql.cc:
  Fix bug#23293 "readline detection broken on NetBSD":
  
  Now that the "libedit" header files declares "rl_completion_entry_function" correctly,
  it need not be cast on usage, and "no_completion()" can be declared to return "char *".

  Fix bug#23293 "readline detection broken on NetBSD":
  
  Now that the "libedit" header files declares "rl_completion_entry_function" correctly,
  it need not be cast on usage, and "complet_func()" is a "CPFunction *" as well.
cmd-line-utils/libedit/readline/readline.h:
  Fix bug#23293 "readline detection broken on NetBSD":
  
  Declare "rl_completion_entry_function()" to be a "CPFunction *", this avoids casts
  and brings "libedit" in sync with "readline".

  BUG#25530 --with-readline fails with commercial source packages
  
  The compile-* scripts should not use --with-readline explicitly when no readline is present.

  BUG#25530 --with-readline fails with commercial source packages
  
  Configuring --with-readline should fail when libreadline is not bundled.
  A system libreadline is only used when there is a bundled libreadline too, so the commercial source code isn't linked with GPL libreadline by accident.

on duplicate key".

INSERT ... SELECT ... ON DUPLICATE KEY UPDATE which was used in
stored routine or as prepared statement and which in its ON DUPLICATE
KEY clause erroneously tried to assign value to a column mentioned only
in its SELECT part was properly emitting error on the first execution
but succeeded on the second and following executions.

Code which is responsible for name resolution of fields mentioned in
UPDATE clause (e.g. see select_insert::prepare()) modifies table list
and Name_resolution_context used in this process. It uses
Name_resolution_context_state::save_state/restore_state() to revert
these modifications. Unfortunately those two methods failed to revert
properly modifications to TABLE_LIST::next_name_resolution_table
and this broke name resolution process for successive executions.

This patch fixes Name_resolution_context_state::save_state/restore_state()
in such way that it properly handles TABLE_LIST::next_name_resolution_table.

sql/item.h:
  Name_resolution_context::save_state/restore_state():
    At the moment these methods are used only by code implementing
    INSERT and INSERT ... SELECT statements. This code doesn't modify
   'next_name_resolution_table' member of table list element
    corresponding to the first table of SELECT clause (pointed by
    'first_name_resolution_table'). But it modifies table list element
    corresponding to the target table of INSERT (pointed by 'table_list')
    So these methods were changed to reflect this.
