Upstream keeps rearranging the deckchairs for these, so let's just
switch to the [roughly] one-liners rather than track that...

In order to implement android::base::WaitForProperty well, we need a way to
wait not for *any* property to change (__system_property_wait_any), but to
specifically wait for the property represented by a given `prop_info` to
change.
The android::base::WaitForProperty implementation, like attempts to cache
system properties in the past, also needs a way to keep serials and values
in sync, but the existing functions don't provide a cheap way to get a
consistent snapshot. Change the __system_property_read_callback callback's
type to include the serial corresponding to the given value.
Add a test, slightly clean up some of the existing tests (and name them to
include the names of the functions they're testing, in our usual style).

Trying to send even 0 bytes to closed socket leads to
broken pipe error. Sometimes property service is just
quick enough and closes the socket between send(valuelen)
and send(value) in the case where valuelen is 0.

This change introduces new __system_property_read_callback
method to use in place of deprecated __system_property_read
__system_property_set() and get() should just work but now
do not have limit on system property names.
