* Include new icons for toolbar overflow to ensure they are tinted correctly and fit in with the rest of the UI.
* Replace custom code for clearing line edits by including a proper icon for the default action.
Definitions:
* Database Key - Cryptographic hash used to perform encrypt/decrypt of the database.
* Database Credentials - User facing term to refer to the collection of Password, Key File, and/or Hardware Key used to derive the Database Key.
Changes:
* Remove the term "master" and "key" from the user's lexicon and clarify the code base based on the definitions above.
* Clean up wording in the UI to be clearer to the end user.
* Only clear password field when switching tabs or minimizing. This prevents the setting "Remember Key Files and Hardware Keys" from being useless with multiple databases.
* Convert key file field to Line Edit, simplifies usage. Fix clear field button as well.
* Removed need for clearForms to check if the database is being opened (was a solution to tab switching while unlocking, no longer a problem).
* Significantly improve user experience when using hardware keys on databases in both GUI and CLI modes. Prevent locking up the YubiKey USB interface for prolonged periods of time. Allows for other apps to use the key concurrently with KeePassXC.
* Improve messages displayed to user when finding keys and when user interaction is required. Output specific error messages when handling hardware keys during database read/write.
* Only poll for keys when previously used or upon user request. Prevent continuously polling keys when accessing the UI such as switching tabs and minimize/maximize.
* Add support for using multiple hardware keys simultaneously. Keys are identified by their serial number which prevents using the wrong key during open and save operations.

The new unlock dialogue seems to confuse users
as to what the purpose of the key file is. This
patch changes the generic "Select file..." affordance
to the more explicit "Select key file..." and adds
a help button to the label just like the one we
already have for the hardware key. Furthermore,
it prevents the user from using the KDBX file as its
own key file (since that would never work anyway).
The change breaks existing translations on purpose
(instead of simply adjusting the en_US locale)
in order to force translators to update this string
for their languages.
Resolves#3678
With this change we get rid of the confusing key component checkboxes.
Now a component is either there or not (if left empty). There is
no redundant distinction between "unset" and "emtpy" anymore.
For compatibility with older databases that have "empty" passwords,
KeePassXC will ask if the user wants to retry with an empty password
if unlocking failed and the password field was left blank.
Besides these functional changes, the widget's layout has been
rearranged to be more compact, less stretched out (e.g. input fields
do not fill the full window width anymore), and more user-friendly
by providing a help tooltip for the hardware key field and accessible
descriptions for screen readers.
The Database, DatabaseWidget, and DatabaseTabWidget classes share many responsibilities in inconsistent ways resulting in impenetrable and unmaintainable code and a diverse set of bugs and architecture restrictions. This patch reworks the architecture, responsibilities of, and dependencies between these classes.
The core changes are:
* Move loading and saving logic from widgets into the Database class
* Get rid of the DatabaseManagerStruct and move all the information contained in it into the Database
* Let database objects keep track of modifications and dirty/clean state instead of handing this to external widgets
* Move GUI interactions for loading and saving from the DatabaseTabWidget into the DatabaseWidget (resolves#2494 as a side-effect)
* Heavily clean up DatabaseTabWidget and degrade it to a slightly glorified QTabWidget
* Use QSharedPointers for all Database objects
* Remove the modifiedImmediate signal and replace it with a markAsModified() method
* Implement proper tabName() method instead of reading back titles from GUI widgets (resolves#1389 and its duplicates #2146#855)
* Fix unwanted AES-KDF downgrade if database uses Argon2 and has CustomData
* Improve code
This patch is also the first major step towards solving issues #476 and #2322.
