Now when user specified 'help' or 'version' flag, the program will process them first and
ignore all other flags (even invalid flags).
This improves program usability since user will be able to consult the help description without
ensuring existing flags are all valid (or removing all flags). And user can refine the flags
after reading the help description.

Sometimes users had not properly configured their system locale and thus
qbt will specify a default locale just in case.

For GUI and non-daemon console, the legal notice won't ask for user acceptance anymore and only
provide an OK button (or Enter key in console) from now on.
For daemon mode, qbt will print the legal notice and continue to run. It will also notify user
to use command line option `--confirm-legal-notice` to suppress the message. The message will be
printed on every start up unless user specify the command line option once.
PR #20080.
The implementation of QTimer::singleShot() uses Qt::PreciseTimer if interval is less than 2 seconds. This isn't mentioned in the docs.
Qt::PreciseTimer increases the system's timer resolution which negatively affects power consumption.
PR #18555.
Closes#18350.
The basic idea is we create a version header template at
"src/base/version.h.in" and the build systems are expected to replace
strings that are enclosed with @ symbols and generate
"src/base/version.h" for other source files to consume/include.
Qt 5.14 introduced new feature related to HighDPI screens support,
this parameter is called "scale factor rounding policy", and it is
intended to improve fractional scale factor support (like 150%).
Qt::PassThrough value guarantee that no any rounding will applied to
scale factor, and will be used as is.
Set Qt::AA_EnableHighDpiScaling application attribute when Qt 5.14.x or
newer is used. This fixes a lot of scaling issues on HiDPI displays.
Unfortunately, this flag must be set only before QApllication object
creation, so the only one place where it can be done is main().
This raises qbt's open file descriptor limit to the available maximum
(within user privileges) and thus users don't need to adjust it
manually anymore.
