getWorkingSet() is slow and it is not always needed. So, it is better not to call it in __init__.

When git repositories are in detached head, `git symbolic-ref` cannot be used.

In this case, `gowork-snapshot` outputs `fatal: ref origin is not a symbolic ref` and create a buildout profile with empty revisions.

After these changes, we try to get from a remote named origin in this case. If this did not work, we output the problematic repository.

I added some minor "cleanups" at the same time.

because other variables are vertically aligned

When git repository is in detached head, there's no symbolic-ref, so we
cannot anything better that assuming there's a remote named "origin"

This reverts commit 6cb00ff0,
because of a regression in InnoDB (https://jira.mariadb.org/browse/MDEV-14614).
Several functional tests started to fail with 10.2.12.

As currently it fallbacks to system's gettext

While testing this merge request : nexedi/erp5!243

The following test was failing for me : https://nexedi.erp5.net/test_result_module/20180107-664D9A6/13

Since numpy is not added as a dependecy for h5py. the testnode didn't upgraded numpy while upgrading h5py. 
Adding numpy as a dependency should fix it

Fixes all cloudooo being given the same port, because of jinja2 variable
scoping.
Also, move to buildout.hash.cfg for md5sum maintenance ease.

Also update README accordingly.
Its becasue now erp5-site is being created automatically using software-type
default and there is no create-erp5-site software-type anymore.

In the particular case of PATH, '' is the same as '.',
which is a bad idea from a security point of view.

fontconfig > 2.12.1 now requires gperf.

This reverts commit 38123b86.

fontconfig was not building any more on many machines (most testnode machines). Revert
until investigation is done.
