block is constructed.  A new function exists to pump these notes out
in a standard way :  print_recent_activity_note.

Module dependencies also updated because of this.

Fixes from Dan Marsden to getremoteaddr() and address_in_subnet() -- getenv() isn't supported under ISAPI (IIS) so we use _SERVER instead. address_in_subnet() had a loop control error.

configuration needed). Used $_POST (with data_submitted(), if
possible) instead.
NOTE: Detected in a lot of places!

Fix for bug 2701.

Credits for the report and the patch go to Samuli Karevaara.

Simplified by removing two optional parameters from forum_print_search_form,
because everyone was using the same values for them!

Also renamed the function to simply forum_search_form, because in the end
noone was using it to PRINT html, it was just put into a variable.

Fix for bug 2705:

Decoupling from the beast that is /mod/forum/lib.php, it was a pity to
include 100+ KB of code so that we could reuse 7-8 lines.

This block also wasn't including that library itself, so after Martin
removed that dependency from courses it was broken as well.

Correcting whitespace, modernizing a bit, removed one notice.

saapi nähdä kauanko.

Thanks Samuli!
