#60 Changes to Delphi, Android, Posix, NextGen, compatiblity

[Daniel Simões de Almeida]

Hello Synapse Community

Attached are the Units modified by "Projeto ACBr", they already have all recent trunk modifications..
http://svn.code.sf.net/p/acbr/code/trunk2/Fontes/Terceiros/synalist/

We are successfully using these Units in various IDE's and Operating Systems:
Delphi: D7 – D28, Windows 32/64, Linux 64, Android 32/64 (including NEXTGEN compiler)
Lazarus/FPC: Windows 32/64 and Linux 32/64

I Hope this document can explain the changes, we made...

• SynaFpc.pas -
  This Unit is being used to define Types that do not exist on some platforms. Such as the AnsiString declaration for the NEXTGEN compiler
  I also recreated in it the StrLCopy and StrLComp methods as they have substantial differences between the various IDEs
  Therefore, Unit SynaFpc has been added as a dependency on several other Units in order to facilitate support for multiple IDEs and compilers

-- SmtpSend.pas --

• Added a new property that allows configuring Email Notifications
  TDeliveryStatusNotificationEvents = (dsnSucecess, dsnFailure, dsnDelay);
  TDeliveryStatusNotification = set of TdeliveryStatusNotificationEvents;
  {:Set of Events where DSN-Delivery Status Notification must occur. The
  Default is an empty Set (on DSN)
  https://www.lifewire.com/what-is-dsn-delivery-status-notification-for-smtp-email-3860942}
  property DeliveryStatusNotification: TDeliveryStatusNotification
  read FDeliveryStatusNotification write FDeliveryStatusNotification default [];
• Added the Method: AuthXOauth2
• Changed the authentication order in TSMTPSend.Login, after failures reported by our users, on some servers

-- MimePart.pas --

• Added the "InlineCode" method, to facilitate conversion calls, using the class's internal properties
• MimeType revised and extended…
• Method "EncodePartHeader", modified, to correctly encode the Header in Encoding

-- MimeMess.pas --

• Added auxiliary methods:
  function InlineCode(Value: string): string;
  function InlineEmail(Value: string): string;
• Added the Property, TargetCharset to allow conversion between different versions of IDE and Operating Systems
  {:System charset type. Default value is charset used by default in your
  operating system.}
  property TargetCharset: TMimeChar read FTargetCharset Write FtargetCharset;

-- ssl_openssl_lib.pas --

• I preferred to keep the same Unit, compatible with OpenSSL 1.0.x to 1.1.x, as this avoids IfDefs and allows the Program to adjust at runtime, to the existing installed libraries
  I applied the Patch suggested at: https://sourceforge.net/p/synalist/feature-requests/19/, and this some other changes
