The access vector table itself is not modified in avtab_map() thus
support passing a const pointer.
Logically the content might be changed by the passed callback, but C
does not support transitive const-ness well, and C also does not support
function overloading, e.g. like for strchr(3).

Since this function is not exported there should not be any external

When the O_PATH emulation fails due to getxattr(2)/setxattr(2) failing
with ENOENT, e.g. because no procfs being available, override the errno
value to EBADF. This avoids confusion to the caller as it would suggest
the target of the operation does not exist, which is not the case:
setfiles: Could not set context for /: No such file or directory

In commit 7d69031, pkgdir_selabel_lookup was updated to return an error
in case of invalid path. Such errors were previously ignored, relying on
the default file_contexts for such path. For example, if the security
context of /data/user/0a is restored, the parsing would fail and the
security context of /data/ used instead (i.e., system_data_file).
Restore this behaviour to avoid spurious error messages.
Test: build & boot bramble; check logcat for "Could not set context for"

Previously, if restorecon was called for a /data subdirectory, the
userid (id of the physical user) was not taken into account. Capture the
userid from the file path and use it to set the security context.
Test: flash & adb push xxx /data/user/10/xxx & verify security context

We are now default restricting bindgen visibility to subpackages. This
change is part of a set of changes adding explicit visibility for
bindgen libraries which are already being used elsewhere.
* If these visibility rules are to allow access by the safe bindings
library which lives elsewhere in the codebase, no action is needed.
* If safe bindings do not exist, and you own this library, now is a good
time to think about producing them and transitioning your (now
enumerated) client list.
* If safe bindings exist, but there is a surprise client of the raw
bindings on this list, now is a good time to talk to them about why
they don't want to use your safe bindings.
