7589f1b3bf vhost_user_fs: increase RLIMIT_NOFILE
Increase the number of open files limit for the sandboxed process to the
maximum allowed in the system. The maximum is obtained by reading the
/proc/sys/fs/nr_open sysctl file, and the setting is done using the setrlimit
syscall. Failure to read or parse the nr_open file, or to set the rlimit
results in a panic.

1befae872d build: Fixed build errors and warnings on AArch64
This is a preparing commit to build and test CH on AArch64. All building
issues were fixed, but no functionality was introduced.
For X86, the logic of code was not changed at all.
For ARM, the architecture specific part is still empty. And we applied
some tricks to workaround lint warnings. But such code will be replaced
later by other commits with real functionality.

4120a7dee9 vhost_user_fs: Add seccomp
Implement seccomp; we use one filter for all threads.
The syscall list comes from the C daemon with syscalls added
as I hit them.

The default behaviour is to kill the process, this normally gets
audit logged.

--seccomp none  disables seccomp
          log   Just logs violations but doesn't stop it
          trap  causes a signal to be be sent that can be trapped.

If you suspect you're hitting a seccomp action then you can
check the audit log;  you could also switch to running with 'log'
to collect a bunch of calls to report.
To see where the syscalls are coming from use 'trap' with a debugger
or coredump to backtrace it.

This can be improved for some syscalls to restrict the parameters
to some syscalls to make them more restrictive.

6aab0a5458 vhost_user_fs: Implement support for optional sandboxing
Implement support for setting up a sandbox for running the

consists on switching to new PID, mount and network namespaces, and
then switching root to the directory to be shared.

Future patches will implement additional hardening features like
dropping capabilities and seccomp filters.

3f09eff6c5 vhost_user_fs: add fs cache request operations
This introduces setupmapping and removemapping methods to server.rs,
passthrough.rs and filesystem.rs in order to support virtiofs dax mode
inside guest.

Since we don't really want the server.rs to know that it is dealing with
vhost-user specifically, this is making it more generic by adding a new
trait which has three functions map()/unmap()/sync() corresponding to
fs_slave_{map, unmap, sync}, server.rs will take anything that implements
the trait.
