osd/osd_types: add num_bytes_hit_set_archive to stats

The tiering agent's life is easier/better if it knows how many bytes these
objects consume (instead of making a conservative guess).

erasure-code: refactor jerasure Liberation parameters checks

Create a virtual function to check for each parameter for Liberation
and its derivations Liber8tion and BlaumRoth. The code is moved around
but is unmodified.

A function reseting the parameters to sane defaults when an error
occurs is introduced. It is slightly different from the code that was
duplicated in Liberation and BlaumRoth. In both cases it now resets w.
It is a noop for Liber8tion because the user cannot modify this
parameter which is always set to the default.

erasure-code: fix BlaumRoth sanity check on w

For the BlaumRoth technique, w+1 must be a prime. This sanity check is
present in the sample code from the jerasure library but was not
implemented in the jerasure plugin.

The default value for w is also changed to match this constraint. The
unit tests is changed to always use the default w instead of forcing it
to w.

osdc/Objecter: drop bad session nref assert

This is a bad assert.  Specifically, handle_osd_op_reply may still be
holding the session ref while it is calling the completion for a previous
request.  This is safe: it is only holding the session ref after it dropped
the global map rwlock because of the per-session completion locks.  The
request in question was already marked completed by the time our thread
took the session lock.

Change CrushWrapper::crush to private

Currently in CrushWrapper, the member "struct crush_map *crush"  is a public member,
so people can break the encapsulation and manipulate directly to the crush structure.

This is not a good practice for encapsulation and will lead to inconsistent if code
mix use the CrushWrapper API and crush C API.A simple example could be:
1.some code use crush_add_rule(C-API) to add a rule, which will not set the have_rmap flag to false in CrushWrapper
2.another code using CrushWrapper trying to look up the newly added rule by name will get a -ENOENT.

This patch move CrushWrapper::crush to private, together with three reverse map(type_rmap, name_rmap, rule_name_rmap)
and also change codes accessing the CrushWrapper::crush to make it compile.

mds: fix replay locking

When replaying EImportFinish/EFragment event, the replay thread may call
MDS::queue_waiters. MDS::queue_waiters() requires its caller to hold the
mds_lock. Otherwise assert(waiter_mutex == __null || waiter_mutex->is_locked())
in Cond::Signal() will be tiggered.

[rgw][s3] Allow colon ':' in access key

When access key contains ':', e.g. `some_info:for_user',
authorization header looks like:

"AWS some_info:for_user:request_signature"

so `auth_str.find(':')` result in auth_id = "some_info",
auth_sign = "for_user:request_signature".

auth_str.rfind(':') solves this issue.
