organizationmap: match authors with organizations
Using the same format as .mailmap, match author names with the
organization sponsoring them, if any. It can be used from the command

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.

common: recursive implementation of config::expand_meta
Using a recursive implementation of variable expansions make it easier
to protect against loops and provide human readable messages when they

It also enables one variable to be substituted multiple times in the

with a variable expansion loop.

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.

ceph-disk: add --prepend-to-path to control execution
/usr/bin is hardcoded in front of some ceph programs which makes it
impossible to control where they are located via the PATH.
The hardcoded path cannot be removed altogether because it will most
likely lead to unexpected and difficult to diagnose problems for
existing installations where the PATH finds the program elsewhere.
The --prepend-to-path flag is added and defaults to /usr/bin : it prepends
to the PATH environment variable. The hardcoded path is removed
and the PATH will be used: since /usr/bin is searched first, the
legacy behavior will not change.
Working around missing integer types is pretty easy. For example, the
__u32 family are Linux-specific types, and using these in Ceph
internally is fine because we can typedef them.
