Add support for queries in /{db}/_all_docs POST

[jiangphcn]

Overview

Allow to POST to /{db}/_all_docs and specify a queries list in the body, the same way you can do with a regular MapReduce view, like

curl -u foo:bar -H "Content-Type: application/json" -X POST -d @multiple_queries.json http://localhost:15984/db97/_all_docs
{"results":[
{"total_rows":30,"rows":[
{"id":"point2","key":"point2","value":{"rev":"1-d942f0ce01647aa0f46518b213b5628e"}},
{"id":"point3","key":"point3","value":{"rev":"1-721fead6e6c8d811a225d5a62d08dfd0"}}
]},
{"total_rows":30,"offset":2,"rows":[
{"id":"point11","key":"point11","value":{"rev":"1-ffb6c2ae737918f8f911e1fce668333e"}},
{"id":"point12","key":"point12","value":{"rev":"1-c32d315f69ce72128244a60d0cbe4628"}},
{"id":"point13","key":"point13","value":{"rev":"1-a9b955ca17f553398cd877629e803c5d"}},
{"id":"point14","key":"point14","value":{"rev":"1-2f2aa0db2a8c35754e7ab2308940f60c"}},
{"id":"point15","key":"point15","value":{"rev":"1-247191505d8fa6b4b9dc426321987b17"}}

multiple_queries.json looks like

    {
        "queries": [
            {
                "keys": [
                    "point2",
                    "point3"
                ]
            },
            {
                "limit": 5,
                "skip": 2
            }
        ]
    }

This also can work against /{db}/_design_docs and /{db}/_local_docs endpoints.
