Introduce a PlatformStyle to handle platform-specific customization of
the UI.
This replaces 'scicon', as well as #ifdefs to determine whether to place
icons on buttons.
The selected PlatformStyle defaults to the platform that the application
was compiled on, but can be overridden from the command line with
`-uiplatform=<x>`.
Also fixes the warning from #6328.
- move ds rounds calculation to wallet
- add cache to / rework anon/denom balance functions
- fix updates on new blocks for ds status on overview page
- fix after rebase
- always clear entries, do not try to reuse them
- unlock coins only when needed (do not unlock them every 10 blocks)
- make logic a bit more strightforward in few places
- clear all expired on timeout (not just the first found)
- add 2 additional statuses on doauto
- run DS checks when mn list sync started, do not wait for full sync
- move most class members to private
QT_NO_KEYWORDS prevents Qt from defining the `foreach`, `signals`,
`slots` and `emit` macros.
Avoid overlap between Qt macros and boost - for example #undef hackiness
in #6421.
- streamline initialization logic for litemode/masternode/ds
- call updateDarksendProgress on setBalance
- format amountAndRounds for 0 balance same way as for normal balance (see c3febd20a8)
- use style='white-space:pre' to show long strings in tooltips correctly, adapt few strings
- small fixes (cleanup naming, notr, use static where possible and get rid of unneeded class members)
- detect denominated but not yet anonymized balance properly or both (GetAnonymizableBalance)
- fix progress calculation by using GetAnonymizableBalance
- do not count MN-like inputs as anonymizable
- denominate faster: if there is enough new inputs after DS started (their sum is greater then "already denominated but not yet anonymized balance")
- allow small amounts to be used in CreateDenominated (modified SelectCoinsDark) but only if they are larger then 1 CENT
- do not use collateral inputs in CreateDenominated (modified SelectCoinsDark)
- convert some int64_t -> CAmount for money related variables/params
- mn replies
- MN should use codes for replies, translations are done on client side (client protocol / min pool peer protocol bump)
- use QString for translation instead of ostream, construct better human readable strings for translators
- progress
- use QString here too
