This is the same technique used by Go's strings.Builder
(https://golang.org/src/strings/builder.go#L45), and for the same
reason. (We can't just use strings.Builder because there's no way to get
the underlying []byte to pass to usermem.IO.CopyIn.)

MM.insertPMAsLocked() passes vma.maxPerms to memmap.Mappable.Translate
(although it unsets AccessType.Write if the vma is private). This
somewhat simplifies handling of pmas, since it means only COW-break
needs to replace existing pmas. However, it also means that a MAP_SHARED
mapping of a file opened O_RDWR dirties the file, regardless of the
mapping's permissions and whether or not the mapping is ever actually
written to with I/O that ignores permissions (e.g.
ptrace(PTRACE_POKEDATA)).
To fix this:
- Change the pma-getting path to request only the permissions that are
required for the calling access.
- Change memmap.Mappable.Translate to take requested permissions, and
return allowed permissions. This preserves the existing behavior in the
common cases where the memmap.Mappable isn't
fsutil.CachingInodeOperations and doesn't care if the translated
platform.File pages are written to.
- Change the MM.getPMAsLocked path to support permission upgrading of
pmas outside of copy-on-write.

It is Implemented without the priority inheritance part given
that gVisor defers scheduling decisions to Go runtime and doesn't
have control over it.

This adds an extra Reflection call to CopyObjectOut, but avoids many small
slice allocations if the object is large, since without this we grow the
backing slice incrementally as we encode more data.

Nothing reads them and they can simply get stale.

We have been unnecessarily creating too many savable types implicitly.
