[regression] FilteringSelect: paging is not visible and the warning is too early

[charly]

Hello,

Example:

<div data-dojo-type="dojox.data.QueryReadStore" 
     data-dojo-props="url:'{{dataUrl}}dojox/data/tests/stores/QueryReadStore.php'/>&jsonchoice=search_customer',
       requestMethod:'get',
       doClientPaging:'true',
       doClientSorting:'false'" 
       data-dojo-id="comboStore2">
</div>
          
<div data-dojo-type="dijit.form.FilteringSelect" 
    data-dojo-props="store:comboStore2, searchAttr:'name', pageSize:5"></div>

Problem:

1. Paging doesn't work.

2. The warning is coming too early after you entered the first letter, "the value entered is not valid". But not in dojo 1.7.2.

3. After selected a item, you cannot clear the input field.

thx charly

I can reproduce the second problem on dojox/data/demos/demo_QueryReadStore_FilteringSelect.html, although I am able to clear the input field. The second problem started with [27966].

Maybe the first problem is solved by ​14895.

possible fix - needs review and testing

1. Paging works but the test file forgot to add doClientPaging=true
   
2. _refreshState() was being called with each keystroke but _SearchMixin needed to override that behavior and wait on search results
   
3. when you blur, the input field is repopulated with the first search value since the php test server does not support searching with an exact value (assumes everything is blah*)

Fix example QueryReadStore server to handle exact match queries as well as wildcard queries. So {name: "a"} now looks for an exact match of "a" to the property "name", rather than matching any word inside of name that starts with a, and {name: "a*"} now matches any item where the name property starts with a (but again, not looking at subsequent words of name).

Fix errors in the test file, in particular where it could be swallowing errors by doing asserts without a d.getTestCallback() or d.getTestErrback().

Allow query on empty string (which returns no rows), refs #15687 !strict.

Allow query on "*" to match all rows, refs #15687 !strict.

Fixes #15687. Allow _SearchBoxMixin to override default key validation.
