9ad6746ccd Use static_cast instead of C-style casts for non-fundamental types (practicalswift)
Pull request description:
A C-style cast is equivalent to try casting in the following order:
1. `const_cast(...)`
2. `static_cast(...)`
3. `const_cast(static_cast(...))`
4. `reinterpret_cast(...)`
5. `const_cast(reinterpret_cast(...))`
By using `static_cast<T>(...)` explicitly we avoid the possibility of an unintentional and dangerous `reinterpret_cast`. Furthermore `static_cast<T>(...)` allows for easier grepping of casts.
For a more thorough discussion, see ["ES.49: If you must use a cast, use a named cast"](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#es49-if-you-must-use-a-cast-use-a-named-cast) in the C++ Core Guidelines (Stroustrup & Sutter).

Instead of passing a StartShutdown reference all the way up from
txdb, give ShowProgress a "resumeable" boolean, which is used to
inform the user if the action will be resumed, but cancel is always
allowed by just calling StartShutdown().
Make splash screen queue its own deletion when it receives the finished
command, instead of relying on WA_DeleteOnClose which doesn't work under
these circumstances.

6de50c3 qt: add network-specific style object (Wladimir J. van der Laan)
Mainly cleanups: Gets rid of isTestNet everywhere, by keeping track
of network-specific theming in a central place.
Also makes GUI no longer dependent on the network ID enumeration, which
alleviates concerns about #4802.
It's strange to be able to close these windows while there is work
in progress.
Also set Qt::WA_DeleteOnClose on both windows to make sure that they
are deleted eventually, no matter what happens.
Needed to build breakage reported by Arnavion on IRC:
qt/splashscreen.cpp: In constructor 'SplashScreen::SplashScreen(const QPixmap&, Qt::WindowFlags, bool)':
qt/splashscreen.cpp:33:98: error: 'FormatFullVersion' was not declared in this scope
contrib/devtools/fix-copyright-headers.py script to be able to perform this maintenance task with ease during the rest of the year, every year. Modifications to contrib/devtools/README.md to document what fix-copyright-headers.py does.
- rebuilt some ui file layout to remove unreal values from the files
- remove an unneeded attribute from an ui file
- add / remove some spaces in files
Remove the need for global references `guiref` and
`splashref` by making the BitcoinGUI and SplashScreen
classes register for the UI interface signals themselves.
Move AppInit2 and Shutdown to a thread.
This allows a more responsive splash screen, prevents 'process does not respond'
messages from the window system and will allow for showing a user friendly
window while shutting down.
Only messages for now, executable names and other file names
can be changed later if necessary and safe.
Do not do an all-sweeping change. Some occurences of Bitcoin-Qt need to
be kept:
- Applicationname: this is used to determine the registry entry names,
we don't want to lose settings over a silly name change.
- Where it refers to the executable name instead of the product name.
Use misc methods of avoiding unnecesary header includes.
Replace int typedefs with int##_t from stdint.h.
Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h.
Normalize QT_VERSION ifs where possible.
Resolve some indirect dependencies as direct ones.
Remove extern declarations from .cpp files.
