Based on a dialog with Sam ( as published at http://dachary.org/?p=2320 ).
* Remove PGBackend-h.rst because PGBackend.h is now in master.
* Fix typos caught by ispell
* Update recovery links to point to PGBackend recover methods
* Workaround formating warning
developer_notes.rst:3: WARNING: Duplicate explicit target name:
"erasurecodepluginexample" which should be legitimate.

* Update to the current state of the ghobject implementaiton and the fact
that they encode the shard_t Although the pool also contains the shard
id, it is less relevant to understand the implementation.
* Update with the erasure code plugin infrastructure and the example
plugin now in master.
* Move jerasure to a separate page to be expanded and link it from the
toc
* Kill the partial read and writes notes as it will probably not be
implemented in the near future. Kill some of the notes because they
are no longer relevant.
* Add a definition for "chunk rank"
* Reword, update schemas, fix typos.

* unify conventions to match those used by jerasure ( data chunk = K,
coding chunk = M, use coding instead of parity, use erasures instead
of erased )
* make lines 80 characters long
* modify the descriptions to take into account that the chunk rank
will encoded in the pool name and not on a per object basis
* remove the doxygen link to ErasureCodeInterface because it fails
doc: asphyxiate does not support class
http://tracker.ceph.com/issues/6115
* only systematic codes are considered at this point ( all jerasure
techniques are systematic). Although the API could be extended to
include non systematic codes, it is probably a case of over
engineering at this point.
* add link to
http://tracker.ceph.com/issues/6113
add ceph osd pool create [name] [key=value]
* update the plugin system description to match the proposed
implementation http://tracker.ceph.com/issues/5877http://tracker.ceph.com/issues/4929 refs #4929

* replace the erasure code plugin abstract interface with a doxygen link
that will be populated when the header shows in master
* update the plugin documentation to reflect the current draft implementation
* fix broken link to PGBackend-h
* add a glossary to define chunk, stripe, shard and strip with a drawing
