Following the discussion on https://github.com/owncloud/client/commit/da45d99b8fed9a37df8031433e11eb574c28a8df 
Also updated the link to the current building instructions.

* make target duration a client option instead of a capability
* simplify algorithm for determining chunk size significantly
* preserve chunk size for the whole propagation, not just per upload
* move options to SyncOptions to avoid depending on ConfigFile
  in the propagator
* move chunk-size adjustment to after a chunk finishes, not when
  a new chunk starts

remove doc-man target in doc/CMakeLists.txt https://github.com/owncloud/client/issues/2153

In particular the `OWNCLOUD_CHUNK_SIZE` as requested per #2449.
I looked through the code and it seems the env vars override the conf file, but I'm not 100 % sure.
The `OWNCLOUD_CRITICAL_FREE_SPACE_BYTES` and `OWNCLOUD_FREE_SPACE_BYTES` are now mentioned in two places.

Previously the check box was checked if *any* of its sub-permissions
were granted. This can hide the fact that only a limited subset of them
are actually granted.

The new behavior is to display as "partially checked" if only some
of the sub-permissions are available. Clicking the check box itself
still toggles between granting all or none of them.

The backtrace seems to indicate that the account is invalid.
I don't know how this can happen, maybe the account's display
name was changed while the app is running?

Backtrace:
Crash: EXC_BAD_ACCESS / KERN_INVALID_ADDRESS at 0x18
  Module "owncloud", in OCC::AccountState::account

The destructor of the PropagateItemJob will access the propagator's
_activeJobList. So the _rootJob needs to be destroyed before it.
Order of destruction is the reverse of the order of the members in
the class. So put it at the end so it can be destroyed first.

I didn't want to touch this visible translated string in a
patch release so I just switched the data.

For Qt versions before 5, we continue to show the build-time version
of OpenSSL but it's clearly marked as such.

In 8ef11a38, we started blacklisting
SoftError for 0 seconds.  But if the two sync happen with less than
1s interval, we would still prevent them to happen.
So make sure we expire if 0 seconds have expired

The backtrace looks like:

  File "atomic_base.h", line 396, in QString::~QString
  File "qlist.h", line 442, in OCC::FolderStatusModel::slotUpdateDirectories

This is the only QList operation, and it may crash if the list is empty.
It can be empty if the propfind returned empty results.
I'm not sure how this can be possible to have an empty list there since
the server is always supposed to return at least one entry, for the directory
itself. But it can happen if a directory was transformed in a file, or
if there is a bug on the server.

Hex literals don't work well with version 10: 0x100000 doesn't do
the right thing.

The previous patch on this file made it a bit too big, so make it a bit smaller
For issue #5600

This is a possible fix for #3850, applying custom window flags (http://doc.qt.io/qt-5.8/qt.html#WindowType-enum) on the connection method dialog. These avoid resizing the dialog and displaying a maximize button on OS X and context help button on Windows.

* Add git revision, if available
* Add SSL runtime version
* Add compile-time Qt version

It is possible to create files with filenames that differ
only by case in NTFS, but most operations such as stat and
open only target one of these by default.

When that happens, we want to avoid uploading incorrect data
and give up on the file.

Typically this situation should never occurr during normal use
of Windows. It can happen, however, when a NTFS partition is
mounted in another OS.

So the title of the column is fully visible.
Adjust the default size and the size policy of the label so it behave
correctly as the window get resized

Issue #5600

Add explanation of how to replace local sync folder to FAQ

On review, after feedback from @phil-davis, he's right that users need
to be fully briefed as to the implications of choosing a clean sync —
especially when they have a large amount of data in their account.

The crash reporter shows many crashes in OwncloudPropagator::scheduleNextJob.
We don't really know what could be the cause, but it's probably because
the _activeJobList contains dangling pointer.
So this patch makes sure to remove all the jobs from this list as they get
destroyed.

On master, the scheduling is different and the tasks abort in another
order
