mon: set next commit in mon command replies
The mon command acks include a version that is used by the client to
determine which version of the map they need to get or wait for in order
to see the effects of their command. Current we are returning
get_last_committed() everywhere, but we are about to commit something (and
waiting for it), which will increase that value by one. As a result,
clients are always getting epoch/version-1 instead of epoch.
This manifested by a LibRadosTier.Promote test that failed becaues the
OSD had the OSDMap updates adding the tier and overlay but not the final
map change that set the cache-mode to writeback. I suspect this is also
the cause of of spurious errors in the past where we've seen misdirected
request errors that made no sense.

Fixes: #7110
In dumpling, the bucket info was separated into bucket entry point and
bucket instance objects. When setting bucket attrs we only ended up
updating the bucket instance object. However, pre-dumpling buckets still
keep everything at the entry-point object, so acl changes didn't affect
anything (because we never updated the entry point). This change just
converts the bucket info into the new format.

erasure-code: ensure that coding chunks are page aligned
When coding chunks are allocated for jerasure, their address must be
aligned to page boundaries. The requirement is actually to be aligned on
a long long boundary but bufferlist do not allow for fine tuning of the
alignment.
If padding is necessary because the total size of the data to be encoded
is not a multiple of the alignment requirements as returned by
get_alignment(), the buffer is not only padded but also rebuilt using
rebuild_page_aligned() to preserve the page alignment that is expected
of the input buffer.
The overhead of rebuilding the whole input buffer when padding is
necessary could be reduced by only reallocating one buffer for the last
data chunk, therefore reducing the amount of data being copied. However,
this optimization is not going to be used if the caller takes care of
the padding, which is likely to be the case most of the time.

test: disable cross process sem tests on non-Linux
How to make this portable:
- MAP_ANONYMOUS -> MAP_ANON (OSX)
- sem_init (anonymous semaphore) needs to be replaced by named
semaphores using sem_open/sem_close. Use a memory address of the sem_t
variable to hack anonymous semaphore behavior.
- sem_getvalue isn't supported on OSX. it is used here to do
sem_wait/sem_post to bring a semaphore back to a specific value. to get
around this we may need to restructure the test so that the semaphore
can be destroyed and re-initialized rather than inspected as its
currently being done.
On OSX (and currently any platform missing the MSG_MORE
macro) the MSG_MORE optimization is disabled. The MSG_NOSIGNAL flag is
available on OSX but is called SO_NOSIGPIPE and must be set via
setsockopt.
