CompOS needs to read the artifacts on authfs that odrefresh has
created and write signature files for them.
(But it no longer needs to create any directories, so removed that.)
Fixes:
avc: denied { open } for comm="compsvc"
path="/data/misc/authfs/1/11/test-artifacts/...art" dev="fuse" ino=81
scontext=u:r:compos:s0 tcontext=u:object_r:authfs_fuse:s0 tclass=file
permissive=0
avc: denied { create } for comm="compsvc" name="compos.info"
scontext=u:r:compos:s0 tcontext=u:object_r:authfs_fuse:s0 tclass=file

If FD use is not allowed, execve(2) returns EACCESS and the process is
killed by SIGSEGV.
Minijail closes any FDs by default and open /dev/null for FD 0-2. For
now, odrefresh doesn't use any FD. But until we could tell minijail to
not create FD 0-2 (which could be arguable), allow the permission.

dex2oat checks $ANDROID_ROOT exist, which is a directory in an authfs
mount. Give it permission to search along the path.
Strictly speaking, this isn't change how dex2oat execute in this
particular case, for now. Functions like LocationIsOnSystemFramework
make sure getenv(ANDROID_ROOT) exists. But either way, for those kind of
location checks, it won't match the mount path in /data/misc/authfs
anyway.

dex2oat currently uses some properties as flags (see
art/libartbase/base/flags.cc). For CompOS, we don't really need such
properties, and actually should avoid global state. So dontaudit
explicitly.

The `__builtin_available` macro is used in used in several libraries in
microdroid, including liblog. The macro internally uses
ro.build.version.{codename,sdk}[1]. This change defines the context for
these properties.

When we compile sepolicy files into a cil file, we first gather all
sepolicy files to create a conf file, and then convert the conf file to
a cil file with checkpolicy. The problem is that checkpolicy is
sensitive to the input order; the conf file should contain statements in
a specific order: classes, initial_sid, access vectors, macros, mls,
etc.
This restriction has made Android.bp migration difficult, and we had to
create a magical module called "se_build_files" to correctly include
source files in the designated order. It works, but significant
readability problem has happened. For example, when we write
":se_build_files{.system_ext_public}", how can we easily figure out that
the tag actually includes plat public + system_ext public + reqd mask,
without taking a look at the build system code?
This change refactors the se_build_files module and se_policy_conf
module, so we can easily see the desginated files for each module, just
like we did in the Android.mk. se_policy_conf module now stably sorts
source files in an order which will make checkpolicy happy.
se_build_files module is also refactored, so one tag can represent
exactly one set of policy files, rather than doing magical works behind
the scene. For example, system_ext public policy module is changed from:
se_policy_conf {
name: "system_ext_pub_policy.conf",
// se_build_files automatically adds plat public and reqd mask
srcs: [":se_build_files{.system_ext_public}"],
}
to:
se_policy_conf {
name: "system_ext_pub_policy.conf",
// se_policy_conf automatically sorts the input files
srcs: [
":se_build_files{.plat_public}",
":se_build_files{.system_ext_public}",
":se_build_files{.reqd_mask}",
],
}
