Pull request description:
This does not remove OpenSSL, but makes our own PRNG the 'main' one; for GetStrongRandBytes, the OpenSSL RNG is still used (indirectly, by feeding its output into our PRNG state).
It includes a few policy changes (regarding what entropy is seeded when).
Before this PR:
* GetRand*:
* OpenSSL
* GetStrongRand*:
* CPU cycle counter
* Perfmon data (on Windows, once 10 min)
* /dev/urandom (or equivalent)
* rdrand (if available)
* From scheduler when idle:
* CPU cycle counter before and after 1ms sleep
* At startup:
* CPU cycle counter before and after 1ms sleep
After this PR:
* GetRand*:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter
* GetStrongRand*:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter
* /dev/urandom (or equivalent)
* OpenSSL
* CPU cycle counter again
* From scheduler when idle:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter before and after 1ms sleep
* Perfmon data (on Windows, once every 10 min)
* At startup:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter
* /dev/urandom (or equivalent)
* OpenSSL
* CPU cycle counter again
* Perfmon data (on Windows, once every 10 min)
The interface of random.h is also simplified, and documentation is added.
This implements most of #14623.

Contains Designer UI files. They are created with Qt Creator, but can be edited using any text editor.
locale
Contains translations. They are periodically updated. The process is described here.
res
Resources such as the icon.
test
Tests.
bitcoingui.(h/cpp)
Represents the main window of the Bitcoin UI.
*model.(h/cpp)
The model. When it has a corresponding controller, it generally inherits from QAbstractTableModel. Models that are used by controllers as helpers inherit from other Qt classes like QValidator.
ClientModel is used by the main application bitcoingui and several models like peertablemodel.
*page.(h/cpp)
A controller. :NAMEpage.cpp generally includes :NAMEmodel.h and forms/:NAME.page.ui with a similar :NAME.
*dialog.(h/cpp)
Various dialogs, e.g. to open a URL. Inherit from QDialog.
paymentserver.(h/cpp)
Used to process BIP21 and BIP70 (see https://github.com/bitcoin/bitcoin/pull/11622) payment URI / requests. Also handles URI based application switching (e.g. when following a bitcoin:... link from a browser).
walletview.(h/cpp)
Represents the view to a single wallet.
Other .h/cpp files
UI elements like BitcoinAmountField, which inherit from QWidget.
bitcoinstrings.cpp: automatically generated
bitcoinunits.(h/cpp): BTC / mBTC / etc handling
callback.h
guiconstants.h: UI colors, app name, etc
guiutil.h: several helper functions
macdockiconhandler.(h/mm): macOS dock icon handler
macnotificationhandler.(h/mm): display notifications in macOS

Using Qt Creator as IDE
You can use Qt Creator as an IDE. This is especially useful if you want to change
the UI layout.
Download and install the community edition of Qt Creator.
