When persist.adb.trace_mask is used to enable verbose logging, avoid
exponential logging when a user runs `adb logcat`. As a side-effect,
set the minimum logging level to include everything when ADB_TRACE is
used on the client (which is something we want anyway).

Test: `adb shell 'setprop persist.adb.trace_mask; killall adbd'; adb logcat`

When device goes offline, user usually has to manually replug the
usb device. This patch tries to solve two offline situations, all
because when adb on host is killed, the adbd on device is not notified.
1. When adb server is killed while pushing a large file to device,
the device is still reading the unfinished large message. So the
device thinks of the CNXN message as part of the previous unfinished
message, so it doesn't reply and the device is in offline state.
The solution is to add a write_msg_lock in atransport struct. And it
kicks the transport only after sending a whole message. By kicking
all transports before exit, we ensure that we don't write part of
a message to any device. So next time we start adb server, the device
should be waiting for a new message.
2. When adb server is killed while pulling a large file from device,
the device is still trying to send the unfinished large message. So
adb on host usually reads data with EOVERFLOW error. This is because
adb on host is reading less than one packet sent from device.
The solution is to use buffered read on host. The max packet size
of bulk transactions in USB 3.0 is 1024 bytes. By preparing an at least
1024 bytes buffer when reading, EOVERFLOW no longer occurs. And teach
adb host to ignore wrong messages.
To be safe, this patch doesn't change any logic on device.

Fix LOG() to properly save and restore errno. Test this properly.
Only do logging if severity is >= the minimum.
Fix dangling if statements in CHECK(), CHECK_STR{EQ,NE}(). Test this
properly.
Fix base logging tests on Windows. All libbase_tests now pass on
Windows.
Change place to lock, so the lock can protect logging of all data in
LogMessage.

Upcoming changes to the shell will require significant additions to
the subprocess code, and it will be cleaner if it's in a separate file.
The only functional change here is a new debug tag specifically for
the shell service. Everything else has been copied exactly as-is in
order to make it easier to determine what's changing in upcoming CLs.

Always use LOG() for debug tracing.
Remove useless D_lock. I believe it is useless to lock just before and after fprintf.
I verified the log output both on host and on device. The output looks fine to me.

The existing format was unreadable; putting the pid and tid first helps
somewhat. Also remove the unused qemu tracing which wasn't called anywhere.

Any output from the LOG family will now go to stderr and logcat on the
device. stderr is usually redirected to a log file, but that is now
inhibited for adbd if being run from a tty (useful when debugging with
the serial console).
This also fixes sending logs to the file on device for the trace mask
of "all". The "all" tag was specifically handled to return early from
the function, preventing the file initialization from happening.

This patch factors out a lot of the basic protocol code: sending OKAY,
sending FAIL, and sending a length-prefixed string.
ADB_TRACE has been non-optional for a long time, so let's just remove
the #ifs.
Also actually build the device tracker test tool (and remove its duplicate).

Renamed readx/writex to ReadFdExactly/WriteFdExactly respectively.
These read/write a full fixed-size buffer. If the whole buffer cannot
be read/written, these functions return an error.
Rename write_string to WriteStringFully.
Move the TEMP_FAILURE_RETRY definition in sysdeps.h out of the
!Windows section. It seems Windows won't actually interrupt a call,
but it's easier to just define it than to #ifdef each call.

Re-commit https://googleplex-android-review.googlesource.com/#/c/519430/
Add fix for win_sdk build.
Add socketpair debug log.
Also output thread information in log on host side.

Most code is copied and pasted from adb.h.
Any file can just include it to enable tracing.
Removed some duplications.
