* (C++) Macros should not be used to define constants
* (C++) Memory should not be managed manually
* (C++) "void*" should not be used in typedefs, member variables, function parameters or return type
* (C++) When the "Rule-of-Zero" is not applicable, the "Rule-of-Five" should be followed
* (C++) "switch" statements should have "default" clauses
* (C++) "explicit" should be used on single-parameter constructors and conversiosn operators
* (C++) Non-const global variables should not be used
Look for RTL and symbolic icon variants for each icon that we load. The
only exception here is Transmission's own icons, where it doesn't make
sense (the way I see it).
* Bump minimum Qt version to 5.6
* Switch from QRegExp to QRegularExpression
While still available, QRegExp has been moved to Qt6::Core5Compat module
and is not part of Qt6::Core.
* Use qIsEffectiveTLD instead of QUrl::topLevelDomain
The latter is not part of Qt6::Core. The former is a private utility in
Qt6::Network; using it for now, until (and if) we switch to something
non-Qt-specific.
* Use QStyle::State_Horizontal state when drawing progress bars
Although available for a long time, this state either didn't apply to
progress bars before Qt 6, or was deduced based on bar size. With Qt 6,
failing to specify it results in bad rendering.
* Don't use QStringRef (and associated methods)
While still available, QStringRef has been moved to Qt6::Core5Compat
module and is not part of Qt6::Core. Related method (e.g.
QString::midRef) have been removed in Qt 6.
* Use Qt::ItemIsAutoTristate instead of Qt::ItemIsTristate
The latter was deprecated and replaced with the former in Qt 5.6.
* Don't use QApplication::globalStrut
This property has been deprecated in Qt 5.15 and removed in Qt 6.
* Use QImage::fromHICON instead of QtWin::fromHICON
WinExtras module (providind the latter helper) has been removed in Qt 6.
* Use QStringDecoder instead of QTextCodec
While still available, QTextCodec has been moved to Qt6::Core5Compat
module and is not part of Qt6::Core.
* Don't forward-declare QStringList
Instead of being a standalone class, its definition has changed to
QList<QString> template specialization in Qt 6.
* Use explicit (since Qt 6) QFileInfo constructor
* Use QDateTime's {to,from}SecsSinceEpoch instead of {to,from}Time_t
The latter was deprecated in Qt 5.8 and removed in Qt 6.
* Don't use QFuture<>'s operator==
It has been removed in Qt 6. Since the original issue this code was
solving was caused by future reuse, just don't reuse futures and create
new finished ones when necessary.
* Use std::vector<> instead of QVector<>
The latter has been changed to a typedef for QList<>, which might not be
what one wants, and which also changed behavior a bit leading to
compilation errors.
* Don't use + for flags, cast to int explicitly
Operator+ for enum values has been deleted in Qt 6, so using operator|
instead. Then, there's no conversion from QFlags<> to QVariant, so need
to cast to int.
* Support Qt 6 in CMake and for MSI packaging
* Remove extra (empty) CMake variable use when constructing Qt target names
* Simplify logic in tr_qt_add_translation CMake helper

Actions' sensitivity was being lazy-updated in response to other events
but accidentally were doing immediate updates in response to torrentsChanged
signals being emitted from TorrentModel. This commit makes that path a
lazy-update as well.

refractor: simplify torrent model signal emissions
The Torrent->Application signal connections make up for about 5% of the
app's memory use. Move this to the TorrentModel so that there are only a
handful of signal connections.
Moving signals to TorrentModel means batch change signals can be emitted
instead of per-change-per-torrent emissions and can be handled that way.
* refactor: don't load the same stock more than once
Some actions share an icon -- for example, "start all", "start now", and
"start" each use "media-playback-start". When this happens, get the icon
once and cache it to avoid hitting the disk more often than necessary.
In addition, the statusbar's network transfer icon was being reloaded in
a periodic upkeep timer, reloading with QIcon::fromTheme each time. Only
give icons are needed, so load them once and cache them.
* refactor: better lookup of torrent mime-type icons
filename-to-mime-type and mime-type-to-icon lookups are both expensive,
so do a better job of detecting top-level folders and caching the icons
based on file suffixes.
This also lets find a good mime icon even if the torrent doesn't have
its 'files' property populated yet from RPC.
This way all the qualifiers (`const`, `volatile`, `mutable`) are grouped
together, e.g. `T const* const x` vs. `const T* const x`. Also helps reading
types right-to-left, e.g. "constant pointer to constant T" vs. "constant
pointer to T which is constant".
There're places where manual intervention is still required as uncrustify
is not ideal (unfortunately), but at least one may rely on it to do the
right thing most of the time (e.g. when sending in a patch).
The style itself is quite different from what we had before but making it
uniform across all the codebase is the key. I also hope that it'll make the
code more readable (YMMV) and less sensitive to further changes.
This refactoring is driven by the need to be able to do true queued RPC calls
(where each successive call uses the result of the previous).
Currently, such queueing of requests is done by assigning them special "magic"
tag numbers, which are then intercepted in one big switch() statement and acted
upon. This (aside from making code greatly unclear) effectively makes each such
queue a singleton, because state passing is restricted to global variables.
We refactor RpcClient to assign an unique tag to each remote call, and then
abstract all the call<->response matching with Qt's future/promise mechanism.
Finally, we introduce a "RPC request queue" class (RpcQueue) which is built on
top of QFutureWatcher and C++11's <functional> library. This class maintains
a queue of functions, where each function receives an RPC response, does
necessary processing, performs another call and finally returns its future.
This has a couple of benefits: 1) it is clearly visible to the user that
the list is filtered (doesn't display all the torrents) even when filter
bar is hidden, 2) doesn't lead to filter bar controls being shifted to
the left/right as when "Show:" label text changes.
Disable "Open Folder" and "Verify Local Data" actions for magnets in
Torrent menu. If more than one torrent is selected, "Verify Local Data"
is enabled but only non-magnets are verified if activated.
Add a few sanity checks when opening folder, just in case.
Split FileTree.{h,cc} and FilterBar.{h,cc} files so that each class
is in its own file.
This breaks translations (some classes got renamed => context changed),
to be fixed by next commit (along with Tx sync).
