0d3d5d4bcb Seccomp_unotify based monitor
Unotify based monitor should bring big performance wins
if the sandboxee heavily uses threading or signals.
Some of the features are not supported in that mode:
- execveat is always allowed instead of just the initial one
- stack traces are not collected on normal exit or if the process is terminated by signal

2f64d3d925 stack_trace: pass fd to sandboxee's memory instead of using process_vm_readv
Libunwind sandbox no longer needs to join sandboxee's userns.
This cleans up a lot of special handling for the libunwind sandbox.

0ec4f07f96 Fix rare failure while starting the global forkserver
This bug only manifests if a lot of fds are open when global forkserver is started.
If the allocated exec_fd number was equal Comms::kSandbox2ClientCommsFD then it would be replaced by the comms fd and result in EACCESS at execveat.

dbaf95c724 Move utility code into sandboxed_api/util
This change should make it less confusing where utility code comes from.
Having it in two places made sense when we were debating whether to publish
Sandbox2 separately, but not any longer.

Follow-up changes will move `sandbox2/util.h` and rename the remaining
`sandbox2/util` folder.
