tsan complained that usb_bulk_write accesses usb_handle members outside
a lock. Fix that, but by moving everything over to C++11 locking.
Note that the old code was checking whether pthread_cond_timedwait returned
a negative value, which it will never do --- it will signal timeout (or
any other error) by returning a positive errno value. The rewrite does
what they appeared to intend to do (break out on timeout), rather than
what they actually did (keep trying forever).

In 3d2904cdf2 we removed the code that broke
Linux USB reads into 4KiB chunks. This patch does the same for Windows. This
improves Windows "adb pull" speeds 6x in my VM. (There was no equivalent
problem with writes, so this change only affects pull speeds.)

The reason behing this change is to increase the adb push/pull speed
with reduceing the number of packets sent between the host and the
device because the communication is heavily bound by packet latency.
The change maintains two way compatibility in the communication
protocol with negotiating a packet size between the target and the
host with the CONNECT packets.
After this change the push/pull speeds improved significantly
(measured from Linux-x86_64 with 100MB of data):
| Old push | Old pull || New push | New pull |
-----------------------------------------------------------
Hammerhead | 4.6 MB/s | 3.9 MB/s || 13.1 MB/s | 16.5 MB/s |
-----------------------------------------------------------
Volantis | 6.0 MB/s | 6.2 MS/s || 25.9 MB/s | 29.0 MB/s |
-----------------------------------------------------------
Fugu | 6.0 MB/s | 5.1 MB/s || 27.9 MB/s | 33.2 MB/s |

- Heuristics associated with translation of kernel messages to
Android user space logs.
- Limit is_prio to 4 characters, we got false positives on hex
values like <register contents> with no alpha chars.
- x11 and other register definitions are not valid tags, en0 is
- fix some Android coding standard issues

- Get rid of log stutter, tag (executable basename) is added by
the logging routines

Add missing \n to uses of legacy D() macro. This should make the legacy
logging easier to read (and harder to miss important stuff).
On POSIX, use gettid() from libcutils instead of pthread_self() so that
the output shows a more reasonable number instead of a pointer value.
This should be ok since libbase's logging already uses gettid().
Win32:
Don't let the Win32 last error get overwritten by API calls after the
original error'ing API. When encountering an unknown error, log the
specific error code.

The code which triggers these events (via the SHELL_EXIT_NOTIFY_FD) are
only called from code which is already guarded by #if !ADB_HOST.
