29787cd291 Clarify variables used in TX callback. 
The power measurement depends on the number of bytes that were valid
from the previous use of the transfer buffer.

The number of bytes to be read to fill the next transfer, is the full
size of the buffer.

8a9af7a1ad hackrf_transfer: report on only actual transfers 
The statistics reported to the user now reflect only completed USB
transfers and do not include information about the empty buffers that
are preloaded with data at the start of a TX operation.

70a04855ac libhackrf: add transfer buffer size access calls 
Applications may need to learn the size of the USB transfer buffer
queue, for example to determine how many bytes will be preloaded with
calls to the TX callback.

a09e9a20ed Overhaul timing in hackrf_transfer. 
Rather than using sleep() for 1s at a time, set up an interval timer
that will fire once per second, and wait in the main loop for either
this or some other event.

On POSIX, the timing is set up with setitimer(), which generates a
SIGALRM signal each time the timer fires. The main loop runs pause() to
wait for any signal.

On Windows, the timing is set up using CreateWaitableTimer, which
provides an event handle that is set each time the timer fires. The main
loop runs WaitForMultipleObjects() to wait on this and an interrupt
event.

The TX and RX callbacks can now stop the main loop immediately when they
stop streaming. This fixes #1019.

eeaaaf3b9b Make use of Win32 functions conditional on _WIN32, not _MSC_VER. 
Using _MSC_VER here means that the choice of signal() versus
SetConsoleCtrlHandler depends on the compiler being used, rather
than the OS being targeted. When built with MinGW rather than MSVC,
this happens to work because MinGW's signal emulation is used, but
that emulation is quite limited.

Instead, be consistent and use the Win32 API when building for that
platform, regardless of compiler.

Note that if building for Cygwin, _WIN32 is not defined and POSIX
APIs are used.
