Linux Steam Integration (LSI) 0.6

This is a rather large release for LSI, focusing on improving compatibility and security for gamers.

This release also features a new LD_PRELOAD based liblsi-redirect.so to help with some bugs in ARK: Survival Evolved and Project Highrise. Read down for more details!

New UI

liblsi-intercept.so

• Transmute vendored SDL libraries to host names
• Prevent games from using vendored libcurl
• Rewrite XNA/Mono dlopen() requests to use host libraries where possible
• Prevent games from using vendored openssl libraries
• Whitelist swiftshader libGLESv2.so
• Prevent games from replacing the rest of mesa libs
• Prevent games from using some common vendored GLU/GLEW libraries
• Redirect broken /Plugins/x86/ dlopen() requests to the proper directory (/Plugins/x86_64/)
• Whitelist libx264 vendoring in the Steam client
• Add new system to allow redirecting LibreSSL linking to a host library, which can be the native libSSL or an alternatively named library (i.e Solus has libssl-libressl.so). This will help to improve security for certain ports, along with the existing SSL/libcurl intercepts.
• Fix preload failures for Mono games attempting to load .dll.so files when the .dll path is the correct one (Helps with "black screen of nope" issues)

liblsi-redirect.so:

• Introduced this LD_PRELOAD based module to fix games on the fly
• Override open() system call to fix "ARK: Survival Evolved" using broken shader assets (requires TheCenter DLC)
• Override fopen64() system call to fix "Project Highrise" attempting to use a preference directory as a file and then crashing
• Introduced profile system to allow explicit + safe matching of games, with a view to extending this in future.

common:

• Lots of cleanups
• Much nicer logging system (LSI_DEBUG=1 steam)
• Introduced a VDF (Valve Data Format) file parser to support multiple Steam installation directories.
• Shared much of the code-base between the various modules.

lsi-settings changes:

• Completely revamped the UI
• Dynamically updates state based on selections
• Writes settings when closing the window, no need for extra buttons
• Uses CSD under supported desktop environments (dynamically)
• Community translations, thank you community!
