Bug 7210

Advisory:
Steam was updated to version 1.0.0.52. Additionally, the following changes were made:
1. "steam" package now pulls in the libraries needed to run Steam without the bundled runtime, that is, using the native system libraries only. This mode is not used by default but can be enabled if STEAM_RUNTIME environment variable is set to 0. This way "Civilization V" is able to run in Steam, for example. 
If a game does not start or fails somehow, the users are encouraged to try it when Steam is started with STEAM_RUNTIME=0.
2. Fixed the problems that did not allow "Unity of Command" and "The Talos Principle" to run in Steam.
3. Disabled saving of the Steam's crash dumps in /tmp/dumps by default. They could consume sizeable amounts of RAM if /tmp is mounted as tmpfs. To re-enable, one needs to set STEAM_ENABLE_DUMPS environment variable to any non-empty value.

Hints for testing

* Please check for regressions if Steam is launched as is, without changes in the environment variables.
* If a game runs OK in Steam, please check that it runs OK when Steam is started as "STEAM_RUNTIME=0 steam" as well.

Known issues

1. Steam reports segmentation fault at the exit if it was started with STEAM_RUNTIME=0.
Similar to https://github.com/ValveSoftware/steam-for-linux/issues/4395
Seems to make no harm.

2. ../vgui_surfacelib/FontManager.cpp (276) : Assertion Failed: descs.Count() >= 1
Seems to make no harm either

3. If /tmp/dumps was present when Steam was launched, it will not disable/enable crash dumps (depending on STEAM_ENABLE_DUMPS). This is intentional because /tmp/dumps could belong to some other application, not Steam. Steam is unable to clean it up due to technical reasons.

The update is sent to expanded testing
