Fixes #1710

Else there will still be outdated tree in the memory and the further sync
will be confused

Relates to #1710

Set OWNCLOUD_CORE_DUMP to anything to get a core dump in case of
crashing.

It failed because the directory where change happened triggered a
notification within the second before, so the event was skipped.

Make Debian GNU/kFreeBSD compile

Do not pretend to immediately terminate the sync but let csync
finish planfully and free the mutex.

CookieJar refactoring required to overcome issues in Shibboleth support

The shibboleth implementation no longer maintains its own QNAM.

Instead, MirallAccessManager now holds a custom QNAM implementation
which saves cookies to a file on disk.

This patch also reduces some complexity wrt the browser window,
which used to be deleted via a roundtrip to its callee, which
is not longer required.

Fixes #1764 and Enterprise bug #165

Going forward, AbstractCredentials::getQNAM() could maybe removed entirely.

Add exclusion for OSX ._<filename> files

There is a HACK from commit fa0a2764
Which save the http user as a user for all credidentials, but that
cannot work with shibboleth

Fixes https://github.com/owncloud/enterprise/issues/175

install doc targets in any case. Thanks for the patch!

If a user only builds some parts of the documentation and afterwards
wants to install owncloud-client afterwards via "make install", the
built parts should be installed in any case.

Fixes #1671 and #1675

bubbleUpSyncResult is only called from slotSyncFinished, so if _engine
is invalid there, it is also invalid in slotSyncFinished

This reverts commit aee7515d.

warning: no previous prototype for ‘set_csync_file_locked_or_open_ext’ [-Wmissing-prototypes]

In case two renames are done on the same file/folder very quickly we
lost the information that the second operation was also a rename. That
was because we tried to get the inode value from a stat on the file once
the first rename was finished. But at that point, the file was already
gone because of the second rename.

Now the original inode is kept and written to db in case the file can
not be stat'ed.

This fixes bug #1737
