The code was passing an fd from adb_open() to android::base::ReadFdToString() which actually
takes a C-Runtime fd (on Windows), so it wasn't working.
The fix is to use APIs that deal with C-Runtime fds:
* unix_open()
* android::base::unique_fd
* unix_lseek() (added in this change)
I also removed an unnecessary call to GetProcessId() since we already have the process id

It doesn't seem like b3c14ec693 was really
waiting for adb server death because the server would write OKAY to the
socket, causing the client to return from ReadOrderlyShutdown() before
the socket was actually closed.
The fix is to read the OKAY and then call ReadOrderlyShutdown() which
will then wait for the socket to be closed.
Test: Made the server hang in adb_server_cleanup() during kill-server
and kill-server would hang (as desired).
Test: To test resilience, tried preventing the server from sending OKAY and
adb kill-server still worked properly.

On Windows, when running adb server nodaemon and pressing Ctrl-C,
adb_server_cleanup (an atexit handler) would call kick_all_transports()
which would eventually fail a CHECK because the current thread was not
equal to the main thread. This is because Ctrl-C is implemented in
Windows by the OS creating a new thread in the process and calling the
Ctrl-C handler from there.
The CHECK fail would print out the CHECK expression and call abort()
which would record a crash in the Windows Event Log, plus would
potentially upload a crashdump to Microsoft's Watson service.
This might be a regression from d51c6df1ef.
The fix is to share more code between platforms, removing the call to
Win32 SetConsoleCtrlHandler() and just use the C Runtime's signal()
implementation which is built upon SetConsoleCtrlHandler(). The signal
handler still ends up being called from another thread, but the handler
is thread-safe enough so this seems to work.
Test: On Win10 and Vista, run adb server nodaemon and then try Ctrl-C,
Ctrl-Break and close console window.

Previously, we were returning the result of SendOkay/SendFail in a few
places after handling a host request, which is incorrect for two
reasons. First, the return type of SendOkay/SendFail is bool, and
handle_host_request was expected to return 0 on success. Second, we
don't care if the SendOkay fails; if we got to that point, we're done
with the request, regardless of whether we succeeded to report our
result. The result of this was a spurious failure result reported after
the initial result, which was ignored by the adb client.

This CL builds the former `libadbd` as a shared library, and moves
`adbd` to using shared libraries.
We can't switch `libadbd` from static to shared library directly, due to
the circular dependency between `libadbd` and `adbd`. In particular,
daemon_service_to_fd() can't be compiled into `libadbd`, as it needs to
be overridden by recovery/minadbd.
This CL creates a static library `libadbd_core` as the common base,
which contains everything from the former `libadbd`. Both of the two
shared library targets `libadbd` and `libadbd_services` depend on
`libadbd_core`.
The `adbd` on device (under both of normal boot and recovery) now
depends on `libadbd.so` and `libadbd_services.so`. recovery/minadbd will
depend on `libadbd.so` and `libminadbd_services.so` in future (after
fully converting recovery to Soong).

Previously, when a TCP connection was disconnected from adbd, we were
registering it with ReconnectHandler, which led to the transport
sticking around after the socket was closed. Due to the naming of
TCP transports in adbd (host-<fd number>), this results in incoming

ends up being the same as a TCP transport that had previously
disconnected.

acquire_one_transport or immediately returning a value that we already
have.

commandline.cpp includes commandline.h which defines
StandardStreamsCallbackInterface which calls fwrite(). In the
compilation unit for commandline.cpp, fwrite is getting remapped to
adb_fwrite (good), but the compilation unit for bugreport.cpp includes
sysdeps.h pretty late, which prevents fwrite from getting remapped to
adb_fwrite.
Apparently when linking, the version of StandardStreamsCallbackInterface
that gets used is the one from bugreport.cpp's compilation unit, which
doesn't call adb_fwrite().
And it's necessary to call adb_fwrite() to get Unicode console output on
Windows.
The fix is to #include "sysdeps.h" earlier in bugreport.cpp. I searched
the other object files for other unremapped calls to printf/fwrite/etc.
and didn't find any.

adb: delete unused members in fdevent.
adb: add `adb raw` to connect to an arbitrary service.
Track pending fdevents, and abort if we see an fdevent ready for
read/write for 5 minutes continuously.
Also, add a service that intentionally starts spinning, to test this.
Test: manually changed timeout to a minute, `adb raw spin`

Tracking fdevents by pointer is dangerous because an fdevent can be
destroyed and recreated at the same address. Add a monotonically
increasing id field to fdevent for this purpose.

Add a command to connect to an arbitrary service, for debugging
purposes.
Test: `adb raw shell:ls`

`adb shell logcat` works, and `adb logcat` should too.
Bug: http://b/110202648
Test: suspended the logd process and manually removed the socket

Implement a nonblocking version of FdConnection. The initial
implementation will be somewhat slower than the blocking one for large
packet sizes, due to an extra copy when coalescing an IOVector into an
apacket, but is still substantially faster for small packets.

adbd has been built as a static executable since the same binary was
copied to the recovery partition where shared library is not supported.
However, since we now support shared library in the recovery partition,
adbd is built as a dynamic executable.
In addition, the dependency from adbd to libdebuggerd_handler is removed
as debuggerd is handled by the dynamic linker.
A few more modules in /system/core are marked as recovery_available:
true as they are transitive dependencies of the dynamic linker.
This change also includes ld.config.recovery.txt which is the linker
config file for the recovery mode. It is installed to /etc/ld.config.txt
and contains linker namespace config for the dynamic binaries under
/sbin.

Test: `adb reboot recovery; adb devices` shows the device ID
Test: Select 'mount /system' in the recovery mode, then `adb shell`.
$ lsof -p `pidof adbd` shows that libm.so, libc.so, etc. are loaded from
the /lib directory.

When using "adb remount" on a deduplicated filesystem, the current
response is a warning that the remount will not work. This patch
allows the user to specify an -R option. This option will reboot to recovery,
run e2fsck to undo deduplication, and then reboot the device where "adb
remount" will then succeed.
In addition, if verity needs to be disabled to remount, it will be disabled in
the same reboot cycle to minimize reboots.

adbd (and its dependencies) are marked as recovery_available:true so
that recovery version of the binary is built separately from the one for
system partition. This allows us to stop copying the system version to
the recovery partition and also opens up the way to enable shared
libraries in the recovery partition. Then we can also build adbd as a
dynamic executable.

An IOVector is a collection of immutable reference counted blocks which
can have its head detached at an arbitrary index. This is extremely
useful for implementing packet-framed protocols like adb on top of a
stream protocol like TCP: a stream reader can read blocks, append them
to the end of the IOVector, and then pull packets off of the front.
This also lends itself naturally towards scatter/gather I/O, which will
enable us to read data from disk and send it across the wire with a
theoretical minimum number of copies in USB, and one extra copy over
TCP.
Since this is basically a generalization of std::deque<Range>, delete
Range and replace its uses with IOVector.

This adds fdsan deallocation sanitization to all fds monitored by
fdevent, which is most of the ones in adb.
