Rename filter and filter_ to qfilter

We currently use 'filter' as the OpCode, QueryRequest and RAPI field
name for representing a query filter. However, since 'filter' is a

Detect globbing patterns as query arguments

Short: this patch enables the use of “gnt-instance list '*.site'”.

Detailed description: This patch changes the command line interface code

The operators “=*” and “!*” do globbing in filters, e.g.:

$ gnt-instance list --no-headers -o name 'name =* "*.site"'
inst1.site.example.com

qlang: Add parser for query filter language

With this parser, command line utilities will be able to provide filters
through query2 in a simplistic language. Example filters:

name  "node3.example.com" 
master or (name "node4.example.com")
be/memory == 128 and name =~ /^web/i...

Add simple query filter parser

This parser reads only the format described by the query2
design document: either an empty filter or an OR operator
with equality checks as operands.
