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
