Group all HAL impls using haldomain attribute This marks all HAL domain implementations with the haldomain attribute so that rules can be written which apply to all HAL implementations. This follows the pattern used for appdomain, netdomain and bluetoothdomain. Test: No change to policy according to sesearch. Bug: 34180936 Change-Id: I0cfe599b0d49feed36538503c226dfce41eb65f6

Annotate most remaining HALs with _client/_server This switches most remaining HALs to the _client/_server approach. To unblock efforts blocked on majority of HALs having to use this model, this change does not remove unnecessary rules from clients of these HALs. That work will be performed in follow-up commits. This commit only adds allow rules and thus does not break existing functionality. The HALs not yet on the _client/_server model after this commit are: * Allocator HAL, because it's non-trivial to declare all apps except isolated apps as clients of this HAL, which they are. * Boot HAL, because it's still on the non-attributized model and I'm waiting for update_engine folks to answer a couple of questions which will let me refactor the policy of this HAL. Test: mmm system/sepolicy Test: Device boots, no new denials Test: Device boots in recovery mode, no new denials Bug: 34170079 Change-Id: I03e6bcec2fa02f14bdf17d11f7367b62c68a14b9

sepolicy: make exec_types in /vendor a subset of vendor_file_type We install all default hal implementations in /vendor/bin/hw along with a few domains that are defined in vendor policy and installed in /vendor. These files MUST be a subset of the global 'vendor_file_type' which is used to address *all files installed in /vendor* throughout the policy.

init_daemon_domain(hal_gnss_default)
Add gnss_device dev_type This grants default access to the new GNSS subsystem for Linux to the GNSS HAL default implementation. The GNSS subsystem creates character devices similar to ttys but without much unneeded complexity. The GNSS device class is specific to location use cases.
