rgw: abstract RGWProcess

RGWProcess is a generic request handler that sends request to the
workqueue for processing.
Add RGWFCGXProcess specialization. Later we'll add a new frontend that
will leverage that.

rgw: add some debug output

Dump request environment when starting processing request. We used to do
it before, but it was recently dropped as part of a cleanup.

rgw: add optional tenant name for swift urls

In order to maintain compatibility with swift clients that expect the
url to also contain a reference to the tenant name, add an optional
param (empty by default) that would add it.

rgw: handle temp url key authorization

Fixes: #3454
Implement auth handling code that checks temp url signature and
expiration. The key that is used for the signature is the bucket owner's
temp url key.

for multiple keys, radosgw-admin can config two keys.

erasure-code: add chunk size calculation helpers

With the current erasure code interface, figuring out the size of a
chunk and the number of chunks for a given object can only be achieved
by calling the encode() method on an actual buffer.

The get_chunk_count, get_data_chunk_count and get_chunk_size helpers are
added and documented.

erasure-code: refactor the example to use chunk size helpers

The get_chunk_size and get_chunk_count methods are implemented using the
code found in the encode() method. The encode method is modified to use
the chunk size helpers.

The unit tests are modified to use the helpers.

erasure-code: jerasure implementation of chunk size helpers

The encode methode uses the get_chunk_size method which is a translation
of the code it previously used for the same purpose. The chunk_count and
chunk_data_count methods return k+m and k respectively. But that will
no longer be the case after local parity is implemented.

erasure-code: erasure code decode interface helper

The decode_concat method is implemented, documented and tested. It is a
convenience method to concatenate chunks into a single bufferlist.

qa: cleanup cephtool/test.sh tmp files

When run in a shared environment ( as opposed as a machine created for
the purpose of running this test only ), it is important to cleanup
leftovers to avoid poluting the /tmp space. Create a common temporary
directory for all tmp files.
