bbdb25f680 Allow hal_usb to call getsockopt on uevent socket
We are making a change to uevent_open_socket() in libcutils related to
setting the receive buffer size of netlink uevent sockets.

After setting SO_RCVBUF, we immediately read it back using getsockopt()
to verify that the setsockopt() call was effective. Only if it was not
effective, we call setsockopt() with SO_RCVBUFFORCE.

getsockopt() previously caused SELinux denials like the following:

 avc: denied { getopt } for comm="usb@1.1-service" scontext=u:r:hal_usb_default:s0 tcontext=u:r:hal_usb_default:s0 tclass=netlink_kobject_uevent_socket permissive=0

9234e00daf hal_attribute_hwservice_client drop '_client'
Since this attribute just associates a hal_attribute
with a given hwservice in the standard way.

Test: boot + sanity + test for denials

343e24a1be hal_attribute_hwservice_client += add_hwservice
For sanity, this makes 'hal_attribute_hwservice_client'
be associated with a specific hwservice thus making things
consistent.

After this change, only configstore, hal_allocator, and the
fwk_* services are inconsistent with all other HALs.

Test: boot device, sanity tests, check for denials

8fc7981885 Find hal_foo_hwservice -> you are hal_foo_client.
Before, it was possible to access a hwservice without declaring
that you were a client.

This introduces the following macro:
hal_attribute_hwservice_client(hal_foo, hal_foo_hwservice)

which makes sure the above implication holds using a neverallow rule.

7ae939e84b Revert "Allow callers of uevent_kernel_*() access to /proc/sys/kernel/overflowuid"
This reverts commit 640e595a68. The
corresponding code in libcutils was removed, so this is now unneeded.
