This will allow pv-wrap to translate a host `LD_PRELOAD` item like
`/usr/$LIB/libMangoHud.so` into a pair of `--ld-preload` options, each
looking like `--ld-preload=/usr/lib32/libMangoHud.so:abi=i386-linux-gnu`.

The only character that cannot appear in a `LD_PRELOAD` path entry is `:`,
so we're free to use that as our representation for extra options.
Instead of just appending the ABI tuple, use a key/value notation so
we can extend later if we need to.

steam-runtime-tools — Steam Runtime integration for the Steam client

The steam-runtime-tools library provides low-level Unix-specific tools and functionality for the Steam client, including the pressure-vessel tool that runs Steam games in containers.

To support multiple architectures (currently only i386 and x86_64 are supported), you will need to build it once for each architecture and install at least the helper tools in /usr/libexec/steam-runtime-tools-0 (the libsteam-runtime-tools-0-helpers package) for every architecture in parallel.

The helper tools are located relative to the shared library, so it's OK to bundle steam-runtime-tools alongside some other stack in this layout:

anything/
    lib/
        x86_64-linux-gnu/
            libsteam-runtime-tools-0.so.0
    libexec/
        steam-runtime-tools-0/
            i386-linux-gnu-*
            x86_64-linux-gnu-*

as long as the program that is linked to libsteam-runtime-tools-0.so.0 can find it (via a RPATH or RUNPATH or by setting the LD_LIBRARY_PATH environment variable).

pressure-vessel — putting Steam in containers

The pressure-vessel/ subdirectory of this project contains the pressure-vessel utilities, which are used by Steam's Steam Linux Runtime compatibility tool to run games in individual game-specific containers. For background on pressure-vessel and SteamLinuxRuntime, please see:
