API: Add new option to zero the DOS stub data when unpacking.
Core: Add UI option to enable/disable the new zero DOS stub data option.
Unpackers: Add support for new zero DOS stub data option.
API: `DontRealignSections` and `ZeroDosStubData` are now default enabled as this is the general 'correct' way to handle most files. (Some files do require the section alignment to happen and some files may use the DOS stub for self-validation and such. Adjust accordingly when using Steamless.)

Unpacker: v10.x86 - Finish implementing SteamStub variant v1.0 (x86) unpacker. (Fixes #22)
This unpacker is currently considered beta. Since I only have 1 sample that uses this variant at the moment, it is not possible to confirm the data and signatures being used are consistent across the board. This variant is also very basic and does not seem to include any means of real protection. (ie. encrypting the code section.) I'd assume this version also did not support x64 files or TLS callbacks so most of the work the other variants can do is left out until other samples prove this needs to support those kinds of features.

Unpacker: v30.x64 - Renamed header field Unknown0003 to HasTlsCallback.
Unpacker: v30.x64 - Add support for handling files packed with TlsCallback overrides.

This feature is currently only supported in this variant for the time being. (Until other samples are provided that have a TlsCallback override for the other variants.)

Renamed SteamStub variant 2.0 to 2.1. This is a major change due to a file being presented that looks to be an earlier version of the 2.x variant. This new (older) file presents like 2.x however, it predates some more common features such as the XTEA encryption seen in 2.1 and newer. This version seems less feature-rich and thus I feel it's actually 2.0. 2020-12-17 23:16:20 -08:00
