Plone-recipe-zope2instance

----------------

- Added new client-home option and let it default to a subfolder of the
buildout-wide var folder with a subfolder of the name of the section.
[hannosch]

- Added limited support for running tests under Zope <= 2.8.
[hannosch]

----------------

- Fixed runzope script generation for Zope 2.8.
[hannosch]

- Cleaned up "./bin/instance test" option handling.
[stefan]

- Removed generator expressions as these aren't supported in < py2.4, which is
used by zope 2.7/8.
[duffyd]

----------------

- Added `access-log-custom` option to be able to use another event logger
than the file one for the access logger.
[tarek]

- Fix instance generation to work on Windows with blanks in the path name.
This closes 188023.
[hannosch, gotti]

- Added 'zeo-client-client' option which results in 'client <value>' inside
<zeoclient>.
[timte, hannosch]

- Made relstorage handling more generic, so it now supports any RelStorage
adapter, including Oracle (which was broken).
[mj]

----------------

- Fix typo in event log parameter name (from "z-log" to "z2-log"), to comply
with the documentation. This closes 190943.
[kdeldycke]

- Create pid and lock file folders if they don't exist.
[kdeldycke]

- Remove hard-coded log level and use the event_log_level parameter to set it
dynamically. This closes 190994.
[kdeldycke]

- Added a test environment, using zc.buildout.testing, and a doctest that
tries the recipe.
[tarek]

- Added an `event-log-custom` option
[tarek]

- Added example for the zope-conf-additional option. This closes 185539.
[klm, hannosch]

- Added `rel-storage` option to be able to wire Zope to RelStorage
(postgresql/oracle) instead of a FileStorage database.
[tarek]

---

- For each entry in recipe-specified 'extra-paths' line, add a 'path' line
to the instance and Zope client zope.conf files.
[klm]

---

- Added the boolean `shared-blob` option, defaulting to `no`. If all of
`zeo-client`, `blob-storage` and `shared-blob` options are set,
the instance will assume the blob directory set by `blob-storage` is shared
with the server instead of streaming 'blob' files through the ZEO connection.
[rochael]

- Changed `ctl.do_foreground()` (which is invoked by the `fg` command
line argument) start Zope in debug mode to emulate the behavior of
`zopectl fg`. This required a little special WIN32 code to make
sure it would work in both `*nix` and Windows.
[smcmahon]

- Added `var` option, which is used to configure the base directory for all
the things going into var.
[hannosch]

- Added `zeo-var` option, which is used in the zeo storage snippets to
configure the zeo var folder.
[hannosch]

- Merged rochael-blobsupport branch. Added support for ZODB 3.8 blob storage
configuration for ZEO clients. This references
https://bugs.launchpad.net/collective.buildout/+bug/179113.
[rochael, hannosch]

- Added `zeo-client-name` option. Defaults to the name of the ZEO client.
