If --with-jemalloc option is not specified, then it defaults to tcmalloc.
If --with-jemalloc is specified, then --without-tcmalloc is required.
Also if a rocksdb static linking is desired --with-librocksdb-static,
do not use --with-jemalloc, as rocksdb uses tcmalloc for builds.
Support for jemalloc in package build and perf stats/heap profiler is
underway

Add a ceph-disk test to first setup an OSD with a separate journal
block device, then tear down the OSD (simulating a failure) and create
a new OSD which re-uses the same journal device.
Add create_dev / destroy_dev helpers that encapsulate the operations
that ensure the partition table is up to date in the kernel and the
symlinks are created as expected. In particular it makes sure the kernel
is aware that the partition table of a newly created device is
empty. If the device previously existed and the kernel was not informed
of the latest partition table updates via partprobe / partx, it may
have cached an old partition table which can create all sorts of
unexpected behaviors such as a failure to create the by-partuuid
symbolic links as described in http://tracker.ceph.com/issues/10146

Loopback and cciss devices have an extra 'p' before the partition
number. Add exceptional handling of these devices.

We observe that the new /dev/disk/by-partuuid/<journal_uuid>
symlink is not always created by udev when reusing a journal
partition. Fix by not changing the uuid of a journal partition
in this case -- instead we can reuse the existing uuid (and
journal_symlink) instead. We also now assert that the symlink
exists before further preparing the OSD.

Encapsulate the compilation steps (install dependencies, autogen.sh,
configure, make check) in the run-make-check.sh script. Update the
developer documentation to point to this script instead of multiple
steps.
It is intended as a tool to help new developer make sure their patch is
sane, it focuses on efficiency (runs make check in parallel if possible)
and coverage (enables docker based tests if possible).

Instead of cloning the repository, create a work directory that has
symbolic links to the original .git, using
https://github.com/git/git/blob/master/contrib/workdir/git-new-workdir
It resolves the problem of fetching a commit that is not attached to any
ref, which is apparently not implemented in the git protocol (discussed
on irc.freenode.net#git).

If we ping before the watch is registered we will get ETIMEDOUT (the ping
is are a read op that will fail to see the watch registration).

Return the bits unmolested.
This is a slight change in that we do not reencode based on the client's
features. However, this is an admin command and the client is generally
the CLI or REST API. It makes more sense to provide the unmolested
bits than to reencode them based on features present in a tool that
never inspects the map.
