Bug: http://b/31532493
Using misaligned pointers forces us to potentially take the address of
members in a packed structure (which is now a warning/error in the
latest Clang). Using memcpy() is the proper way to handle this kind of
problem, as the compiler can insert the proper instructions (and usually
elide the memcpy() entirely).
Test: Built correctly with updated compilers.

This CL moves the network address parsing function from adb to libbase
so that it can be used by fastboot as well as adb.
libbase seemed like the right choice because:
1. It already has some parsing functions (parseint)
2. The net address parsing function uses the libbase string
functions so we have a libbase dependency anyway.
The parsing function has been modified slightly to make the canonical
address optional, and debug logging on success has been removed.
For adb the only functional difference is that parsing a network
address will no longer print the result to the debug log, which seemed
unnecessary.

ae5a6c06cd made adb push use
android::base::ReadFileToString() for small files, but that API did not
support UTF-8 filenames on Windows, until this fix which does the
following:
- Add android::base::{WideToUTF8,UTF8ToWide}() which are only available
on Windows. The signatures are based on Chromium's APIs of the same
name.
- Add the namespace android::base::utf8 which has versions of APIs that
take UTF-8 strings. To use this, make sure your code is in a namespace
and then do "using namespace android::base::utf8;". On Windows, this will
make calls to open() call android::base::utf8::open(), and on other
platforms, it will just call the regular ::open().
- Make ReadFileToString() and WriteStringToFile() use utf8::open() and
utf8::unlink().
- Adapt unittests from Chromium.
- fastboot needs to link with libcutils because it links with libbase
which depends on libcutils for gettid() for logging.

At runtime, vsnprintf (and android::base::StringPrintf which calls it)
call a mingw version of vsnprintf, not the vsnprintf from MSVCRT.DLL.
The mingw version properly understands %zd and PRIu64 (the latter,
provided that you #include <inttypes.h>).
The problem was that android::base::StringPrintf was causing
compile-time errors saying that %zd and PRIu64 were not recognized. It
seems that this was because the attribute on the function prototypes
specified `printf' instead of `gnu_printf'. Once that was fixed to match
vsnprintf's attribute, the warnings went away.
This uses similar preprocessor techniques as <android/log.h>.
Also restore a %zd usage to avoid a static_cast<>, and make
print_transfer_progress()'s format string compile-time checkable (and
tweak some types and %llu => PRIu64).

The adb emu command was never working because the socket connection to
the emulator was closed without reading all of the data that the
emulator sent. On Windows, this caused the emulator's recv() call to
error-out, so it never got the command that was sent.
Before settling on this fix, I also experimented changing the arguments
to the socket shutdown() call and that didn't seem to help. I also tried
removing the call to shutdown() and that didn't help. So that should
rule out shutdown() as the problem. One experiment that helped was
delaying before calling adb_close(), but that is of course fragile and
doesn't address the real issue, which is not closing the socket until
the commands have been read.
