Support netd to load resolv Apex.
Switch namespaces when switching library paths between
/system and the APEX, so that internal library dependencies in both
locations are loaded from their own directory.

vsock is a socket address family for communicating into and out of
virtual machines. Addresses have a port and CID. The CID is unique to
each virtual machine on the computer. The VM host always has CID 2.
http://man7.org/linux/man-pages/man7/vsock.7.html
Inside the android guest, the adb daemon hosts a vsock server with
VMADDR_CID_ANY, automatically using the guest CID. The adb server
can now connect to addresses of the form vsock:cid:port, where the CID
must be specified and the port defaults to 5555.
This is a significant speed improvement for ADB connections in
Cuttlefish, with 150-200 MB/s for `adb push` and 100-150 MB/s for
`adb pull`. It also allows removing some proxying steps from Cuttlefish,
simplifying the full connection path, and removes a dependency on the
unstable ivshmem protocol.
Commands tested against a Cuttlefish VM with CID 3:
adb connect vsock:3:5555
adb -s vsock:3:5555 shell
adb disconnect vsock:3:5555
Supporting "adb disconnect" and "adb -s" required modifying some of the
parts that parse addresses / serials.

Since we are moving the fstab from DT into the ramdisk fstab, the
logging from ReadFstabFromDt when reading the default fstab is
turning into logging noise.

There are currently two copies of DwarfOp callback tables in
data.rel.ro section, and that is 16KB of dirty memory per process on a
64-bit platform.
To reduce memory usage, we introduce a layer of indirection so that
all instances of DwarfOp can share a single callback table. We also
get rid of the pointers for op names in the callback table so that the
entire table can be placed in rodata section.
Test result shows 1MB saving on cuttlefish, and 750KB saving on a Go
device (32-bit ARM).

Move APEX symlink creation to alternative module, one that
is targeted at /system not /. Also added comments to reflect
the tenuous connection between the module chosen and the
symlink creation.
Tested with:
rm -rf out/target/product/taimen/system \
&& make droid \
&& ls -l out/target/product/taimen/system/usr
Test: See above
