283928ad55 Auto merge of #925 - christianpoveda:environ-shim, r=RalfJung 
Write name and value for each env var

In order to res0lve https://github.com/rust-lang/miri/issues/756 is necessary to have the whole `"NAME=VALUE"` sequence of bytes written into memory instead of just the value.

This change does not affect the interface of the `shim::envs::EnvVars` type in any way.

631d5facba Auto merge of #914 - christianpoveda:use-host-rng, r=RalfJung 
Use host's rng when communication is enabled

This uses the host's randomness when the communication enabled flag is used. I am not sure about the error handling. I was thinking about fallbacking to `rand` if `getrandom` fails and also print something so the user knows miri is not using the host's rng because it failed. Let me know what you think.

Do nothing when we try to generate random data of length 0 
This preserves compatibility with programs that pass a null pointer and
a length of zero to getrandom(), or their platform's equivalent.
