ReplicatedPG: merge apply_ctx_scrub_stats into apply_stats
The only way the two aren't called essentially atomically is when the
ECBackend needs to delay a write for rmw. In such a case, we actually
want to delay the scrub_cstat application as well since otherwise, we'd
have to flush the backend before settling up at the end of scrub.
Perhaps this should be a separate function to distinguish between the
replica+primary info update and the primary scrub_cstat update, but that
seems more complicated than it's really worth.

cmake: fix boost build on ubuntu yakkety
If the host system has boost version 1.61 or higher (as in the case
for ubuntu 16.10 yakkety) the ceph build is currently broken. it
will pickup the system boost libraries but use the headers from the
submodule.
This commit ensure that when WITH_SYSTEM_BOOST is OFF we always
use the boost libraries and headers built from the submodule.

test/osd-fast-mark-down.sh: wrong assumption on first subtest
First subtest checks for proper behavior when "osd fast fail on
connection refused" is disabled, yet it doesn't disable it and
fails, as is it enabled by default.
Revert "rgw: temporarily use std::vector in place of static_vector of Boost."
This reverts commit bc23e0f7fa8491c44fa938eeb954197f6aad2367.
We're doing that because the reverted commit was a makeshift
solution to not fail Ceph compilation on platforms lacking
Boost modern enough to ship the container/static_vector.hpp.
As we got the in-tree Boost the commit isn't necessary anymore.

tests: fix ceph-helpers.sh wait_for_clean delays
The TENTH_TIMEOUT was not delcared as an int and failed to be set with
the correct number. The test of the function did not catch this.
Implement computing of the increasingly large sleep delays in a separate
function so that it can be tested more easily. Give up on sub-second
sleep because a the function will not sleep at all if the cluster is
already clean. And if it is not already clean, it is very unlikely to
become clean within less than a second. The downside of having very
short sleep time is that it needlessly stress the machine and also
possibly spam the logs.

librados: drop io_ctx_impl on ioctx_create/create2
close() was never called for the passed in IoCtx which
could probably result in an IoCtx leak if the original
IoCtx was a valid pool context allocated earlier.
Its kind of better to do it here rather than to leave
the destruction on the caller for better (or cleaner)
common case handling.
rgw: compilation of the ASIO front-end is enabled by default.
We're changing the default value because the previous one was
a makeshift solution to not fail Ceph compilation due to
the Beast's dependency on Boost >= 1.54 that wasn't available
on CentoOS 7. As we got the in-tree Boost we can compile
the ASIO front-end by default.

tests: save 9 characters for asok paths
For vstart.sh powered tests, save 9 characters in the path name
by replacing testdir/test- with td/t-
60 characters imposed by jenkins
9 characters for src/test
5 characters for td/t-
33 left (instead of 24) for the test to create asok such as out/client.admin.25327.asok
Moving these files outside of the build directory is a bad idea because
tests should only create/use files within the builddir and not write
outside of this directory. Doing so would make things more complicated
for cleanup in case the test fail and create other problems as a
consequence (filling out disk space, conflicting directories between
runs etc.).
For ceph-helpers.sh tests replace testdir with td, saving 5 characters.
This is not strictly necessary but keeps the directory names consistent:
if the developer wants to get rid of all the test leftovers, it is
enough to remove the a single directory: td.

The recent change to do this logic with file copy (and in src/rgw)

Move the copy into a custom target which will always source the

osd/: cleanup the snap trimmer and deal with delayed repops
With the PGBackend changes, it's not necessarily the case that
calling simple_opc_submit syncronously updates the SnapMapper.
Thus, we can't rely on being able to just ask the snap mapper
for the next object immediately (we could well loop on the same
one if ECBackend is flushing the pipeline). Instead, update
SnapMapper and the SnapTrimmer to grab N at a time.
Additionally, we need to make sure we don't try this again until
all of the previously submitted repops are flushed (a good idea
anyway). To that end, this patch also refactors the SnapTrimmer
machine to be fully explicit about why it's blocked so we can be
sure that we don't queue an async work item unless we really
want to.

osd/ECBackend: use an explicit backfill field on ECSubWrite
Previously, we used an empty transaction to indicate when we
were sending the op to a backfill peer which needs the logs,
but can't run the transaction. I'd like to be able to send
and empty transaction for the rollforward side effect without
it causing the peer to think it missed a backfill op, so
instead, use an explicit flag. Compatability is handled by
interpretting an old version encoding with an empty transaction
as having the backfill field filled.
