5702c6ff45 Finish <search.h>.
I'm unable to find a bug, but we've had requests for this internally
once or twice (though I pointed those folks at the STL), and there's
code we build for the host or in our bootloaders that would use this,
and there's reasonable-looking FreeBSD implementation ready and waiting.

f11aa95ee7 Pretend the <fts.h> functions didn't appear until 21.
Because there was an accidental ABI breakage in 21, and we can't fix
the past. It seems more useful to refuse to build code that won't work
on any current or future device.

5f7135eddd Allow calling v?dprintf for any target API level.
Old versions of Android called these fdprintf and vfdprintf out of
fears that the glibc names would collide with user debug printfs.

Allow users to just use dprintf and vfdprintf on any version by
renaming those calls to their legacy equivalents if needed.

a0d374d587 Add __system_property_wait and return the serial in __system_property_read_callback.
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).

of NDK. Call to this function will result in abort for apps
targeting Android O.

5ffed9b856 Move brillo closer to Android.

mean worse interoperability.

just alternative interfaces to utimensat(2) system call) lets us clean up
without breaking anything.

722ab05b25 bionic: Implement getpwent and getgrent
Not efficient to iterate through given the large number of Android
ids (AID). Compile warning will result if you use these functions,
telling you as much. Not for general consumption, however for
example, some filesystem tests would like to see these to perform
all corners.

About 1/4 second for getpwent, and 1/8 second for getgrent to iterate
through all reserved Android aids.

android_net_res_stats_get_usable_servers uses the data returned by
android_net_res_stats_aggregate to determine which of the servers are
considered valid or broken by the resolver.

If we decide we're going to mandate quota functionality, I'm happy for us to

there's not much to test here other than "will it compile?". The strace
