The legacy time_daemon binary relied on the old Android alarm dri-
ver for setting RTC at bootup. Once /dev/alarm support was removed
we found that time cannot be restored properly, unless a data con-
nection was available for NTP sync.
However, the blob already has a fallback mechanism that relies on
settimeofday(), except that it could never work properly. While
time_daemon is started under UID/GID of root, it immediately drops
to system/net_raw, which is required for subsequent socket commu-
ications (e.g., QMI, modem, etc).
The issue was that any UID transition from root triggers the remo-
val of all thread capabilities, including CAP_SYS_TIME, required
for settimeofday() or other RTC adjustments. Thus, time_daemon was
edited to skip the internal set[gu]id() calls altoghether, in order
to use the new capabilities mechanism introduced with Oreo init.

Audio calibration delta files folder created at
/data/misc/audio/acdbdata/delta.
Path changed to provide access to media server.
Added /data/audio/acdbdata/delta path also
for backward compatibility

* The creation of /data/misc/wifi and /data/misc/dhcp was moved long ago
to the core init.rc script. Moreover, /data/misc/wifi is deprecated
since wpa_supplicant now relies on /data/vendor/wifi.

This addresses an underlying problem since /dev/hw_random is used. The
issue is that EntropyMixer, which runs in system_server, needs to read
from /dev/hw_random, but thanks to our qualcomm ueventd, EntropyMixer
can never accress this node, resulting in warnings like this:
W EntropyMixer: Failed to add HW RNG output to entropy pool
W EntropyMixer: java.io.FileNotFoundException: /dev/hw_random (Permission denied)
AOSP ueventd handles this well, so just remove this line to get things
back to stage. This issue was never exposed because Google derps the
logging here, which is already fixed on Pie.

Framework will now add interface to supplicant (via HIDL) when it
needs to control an interface, so don't specify them in the startup
params.

Wpa_supplicant's random pool is not necessary on Android. Randomness
is already provided by the entropymixer service which ensures
sufficient entropy is maintained across reboots. Commit b410eb1913
'Initialize /dev/urandom earlier in boot' seeds /dev/urandom with
that entropy before either wpa_supplicant or hostapd are run.

Test: Use wifi and wifi tethering on 8974 targets
