Since everything fits inside an int64, we avoid using crypto/rand.Int, which
can allocate and uses the much more complex big.Int.

Remove three syserror entries duplicated in linuxerr. Because of the
linuxerr.Equals method, this is a mere change of return values from
syserror to linuxerr definitions.
Done with only these three errnos as CLs removing all grow to a significantly
large size.

Split usermem package to help remove syserror dependency in go_marshal.
New hostarch package contains code not dependent on syserror.

The syscall package has been deprecated in favor of golang.org/x/sys.
Note that syscall is still used in the following places:
- pkg/sentry/socket/hostinet/stack.go: some netlink related functionalities
are not yet available in golang.org/x/sys.
- syscall.Stat_t is still used in some places because os.FileInfo.Sys() still
returns it and not unix.Stat_t.

- Rewrite arch.Stack.{Push,Pop}. For the most part, stack now
implements marshal.CopyContext and can be used as the target of
marshal operations. Stack.Push had some extra logic for
automatically null-terminating slices. This was only used for two
specific types of slices, and is now handled explicitly.
- Delete usermem.CopyObject{In,Out}.
- Replace most remaining uses of the encoding/binary package with
go-marshal. Most of these were using the binary package to compute
the size of a struct, which go-marshal can directly replace. ~3 uses
of the binary package remain. These aren't reasonably replaceable by
go-marshal: for example one use is to construct the syscall
trampoline for systrap.
- Fill out remaining convenience wrappers in the primitive package.

Because the abi will depend on the core types for marshalling (usermem,
context, safemem, safecopy), these need to be flattened from the sentry
directory. These packages contain no sentry-specific details.

* Rename syncutil to sync.
* Add aliases to sync types.
* Replace existing usage of standard library sync package.
This will make it easier to swap out synchronization primitives. For example,
this will allow us to use primitives from github.com/sasha-s/go-deadlock to
check for lock ordering violations.

This change also adds extensive testing to the p9 package via mocks. The sanity
checks and type checks are moved from the gofer into the core package, where
they can be more easily validated.
