Host services are attempted after handle_host_request, which means that
failing to find a transport to give to handle_forward_request shouldn't
send an error over to the other end.

Test: `adb track-devices` with multiple devices connected

This change uses a context manager to create the fake ADB servers (and
cleanly tear them down.

This change returns a different value (-EALREADY) when a connection has
already been established, as opposed to a real connection failure (which
still returns -1).

Plumb the transport that we received the adb reverse request on through
to reverse_service, instead of trying to get a unique transport on
devices that have multiple active transports (e.g. a device with USB
(even unplugged) connected via TCP).

Previously, processes started via `adb shell` have an oom_score_adj of
-1000, making them invisible to the oom killer. This makes running a
process that consumes all memory (e.g. by leaking in a loop) lead to
the entire rest of the system (including adbd, because of bad
heuristics in the kernel) being oom killed before getting to it.

Switch from using std::string as the type we use to hold our payload in
apacket to a custom reimplementation that doesn't zero initialize. This
improves bulk transfer throughput in the adb_benchmark microbenchmark
on walleye by ~20%.

OS X reports maxPacketSize as wMaxPacketSize * (bMaxBurst + 1) in the
deprecated GetPipeProperties function. Use the also-deprecated
GetPipePropetiesV2 API to get bMaxBurst and figure out what
wMaxPacketSize is. (This file is going to go away eventually, so don't
bother with switching to the recommended GetPipePropertiesV3, since
it would be a substantially larger charge.)
libusb is unaffected.

This change splits the capability-dropping step of adbd into two. This
is more robust when ambient capabilities are being used, since minijail
cannot currently handle that case.

Profiling of adb_benchmark revealed that something like half of the CPU
time was being spent in malloc and free, which was odd because the
benchmark repeatedly mallocs and frees allocations of the same size. It
turns out that our default configuration of jemalloc will purge after
every free. Configure jemalloc to not do this, for gains of over 100%
on adb_benchmark, and up to 25% (on walleye USB3) in real-life.

When connecting to an address, we construct a transport first, and then
check whether we've already connected to that address. The consequent
destruction of the BlockingConnectionAdapter attempts to join threads
that haven't been started, which aborts.
Make it safe to destruct a BlockingConnectionAdapter without calling
Start on it first, to solve this.

On platforms that implement sockets via underlying sockets (e.g. Wine),
a socket can appear to be full, and then become available for writes
again without read being called on the other end. Add a sleep after
each write to give the underlying implementation time to flush.
This doesn't help us if the buffer size is smaller than MAX_PAYLOAD,
but at least in the case of Wine, that doesn't seem to be the case.
