env shim: make sure we clean up all the memory we allocate

`Machine` memory is not leak-checked, so if we forgot to deallocate part of the env shim memory, we wouldn't even notice. Thus add a dedicated memory kind that is leak-checked.

Add directory-related shims

This PR adds support for `mkdir`, `rmdir`, `opendir`, `closedir`, and `readdir64_r`.

Open directory streams are tracked through a HashMap indexed by pointer locations, which holds directory iterators. Since `DIR` is an opaque type in glibc, I represent them with 1-byte allocations, and then just use their pointers in HashMap lookups.

Tests are included to exercise the new functionality.

Support unwinding after a panic 
Fixes #658

This commit adds support for unwinding after a panic. It requires a
companion rustc PR to be merged, in order for the necessary hooks to
work properly.

Currently implemented:
* Selecting between unwind/abort mode based on the rustc Session
* Properly popping off stack frames, unwinding back the caller
* Running 'unwind' blocks in Mir terminators

Not yet implemented:
* 'Abort' terminators

This PR was getting fairly large, so I decided to open it for review without
implementing 'Abort' terminator support. This could either be added on
to this PR, or merged separately.

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.
