The APIs that are tagged with # vndk are actually for LLNDK libraries.
Although LLNDK is part of VNDK, calling those APIs 'vndk' has given
users a wrong perception that the APIs don't need to be kept stable
because that's the norm for most of the VNDK libraries that are not
LLNDK.
In order to eliminate the misunderstanding, rename the tag to 'llndk' so
that people introducing new such API will realize what they are signing
themselves up for.

libsync is used both by platform (e.g. libui.so) and by same-process
HALs (e.g. android.hardware.graphics.mapper@2.0-impl.so). Therefore it
is eligible for either VNDK-SP or LL-NDK. Among the two choices, LL-NDK
was selected because it is already an NDK and is just a thin wrapper
around a few kernel ioctls.
However, since libui (which is a vendor_available:true library) is using
more symbols that are not available to NDK clients, the extra symbols
are exposed as # vndk tag so that they are only available to VNDK
clients, but not to NDK clients.

The header names were changed during review, but the library map file
wasn't updated.

The new header provides an updated interface to libsync appropriate
for the NDK. Clients use existing syscalls where possible (e.g. poll()
instead of sync_wait()), and the remaining functions return structures
used in mainline Linux kernels rather than the Android staging sync
framework.
Over time, framework clients will be migrated to using the NDK
interface, which will eventually replace the current internal
interface. The only difference is the header will be named
<android/sync.h> in the NDK and <sync/sync.h> internally.
