Add EMV functionality (#1080)

* Add basic strcture needed for EMV implementation * Add demo EMV functionality with C code pasted in a very dirty and unsafe way. NOT FINAL * Refactor IccExtractor Structure * Fix Makefile * fix include file * move global variables from h to c * revert to memcpy * fix icc data recovery functions * Add EMV functionalities on windows * Make EMVToken structures like SecurityToken * Define constants instead of hard coded values * Token structures created with inheritance * refactor TokenKeyfile to use inherit. + polymor. * add Token.h + Token.cpp in modules in VS2010 * Add a comment at each use of SecurityToken class or objects * SecurityTokenKeyfilesDialog preparation * Implemennt GetAvailableTokens in Token class on windows * merge * up (patching for Windows) * foreach Token.cpp corrected * Display EMV keyfiles on first window in graphic interface * Add token to Windows UI * EMVToken selection on OKButton on Linux * Keyfile.cpp optimization * Move getKeyfileData in the token class * EMV::Token GetAvailableKeyfiles() base * Move getKeyfileData in the token class on unix * Remove test comments * Warnings resolved * RemoveeSecurityTokenLibraryNotInitialized exception if at least one emv token is detected * Adding new files * Remove old files and add the new version to the windows project * Change make_shared to shared_ptr constructor * IccExtractor integration working on linux * Throwing card not EMV execption * catch error when not EMV type in EMVToken::GetAvailableKeyfiles * Change types to compile on windows * list all keyfiles, security keyfiles and emv keyfiles in command line * Change type to be coherent and remove old todo comments * Remove todo comments * Change indentation and resolve a bug from previous commit * Use polymorphism for GetKeyfileData and add export option for EMVTokens on Linux * Linux : Allow to export EMV Tokens in command lines, Windows : Disable the delete button when EMV Keyfiles are selected * Remove SlotId from TokenInfo as it is already in Token * Correct errors on Linux * Disable delete option if one EMV Token is selected on Linux * Fix bug enabling delete button if nothing is selected * emv data used as reference then burnt * use of normal files in linux corrected * help updated * help updated for export functionnality * option EMV added to graphic interface but not yet working * Bug fix : Allow to use multiple EMV on windows * EMV Option added to UserPreferences * EMV Option working for Linux * EMV option added to Windows (not working yet) * [NOT TESTED] EMV option for Windows * Working EMV option on Windows * EMV Option for data extraction working for volume creation * EMV Option for data extraction working for Mount * EMV Option for data extraction working for mounting favorites volumes * EMV Option for extraction working for Changing volume password, Set Derivation Key Algorithm and Add or remove keyfile from volume * Windows : re-checking EMV Option when getting data * Removing error catches in the IccDataExtractor classe (It only throws error now). Changing GetPan signature to resemble the other functions signatures more * Changing EMV errors - Only throwing ICCExtractionException from outside of the ICC module. - Catching all TLVExceptions and PCSCExceptions to throw the right ICCExtractionException - Deleting APDU exceptions. * First version of the documentation * Adding function pointers for winscard library (but it crashes VeraCrypt) * Debugging function pointers * The import of the library on windows work as expected now * Reverting EMVToken.cpp changes used to test to library import * Searching for the System32 path instead of hard codding it * Fixing the bug were VeraCrypt crashes if there is no readers when "add Token files" is clicked * Winscard library not initialized in object constructor anymore to delay it after EMVOption check * Remove winscard lib from windows dependencies * Properly displaying errors * Adding a dot in Language.xml * Catching TLVException * Removing unused code * Remove unusefull comments * Trying to fix 0x1f error * Update IccDataExtractor.cpp * Delete History.xml * Fix get data without get pan * Cleanup code * changes for linux compilation but linking not working * error handling for linux * erasing emv data * Burn PAN * Burn PAN from memory * Uncomment selfcheck before merging master * burn corrected * EMV errors handling for Linux * EMV working for Linux CLI * Doc : Winscard Linux package and VeraCrypt versions --------- Co-authored-by: doriandu45 <d45.poubelle@gmail.com> Co-authored-by: red4game <redemgaiming@gmail.com> Co-authored-by: Brice.Namy <brice.namy@insa-rennes.fr> Co-authored-by: vocthor <pieceo108@gmail.com> Co-authored-by: vocthor <67202139+vocthor@users.noreply.github.com> Co-authored-by: Andrei COCAN <andrei.cocan@insa-rennes.fr> Co-authored-by: AndreiCocan <95496161+AndreiCocan@users.noreply.github.com> Co-authored-by: francoisLEROUX <francois3443@gmail.com>
