8ba15ad0b1 Make the 'do_exit' flag static
Both libhackrf and hackrf_transfer are using boolean flag named
"do_exit" which is not static. This is problematic because the flag is
used for different things. This patch fixes the problem by making the
flag static in both places.

cccde1b431 hackrf_transfer - cast with uint32_t
The compiler (MSVC 2013) didnt have the uint typedef,
switched to using uint32_t which is the type of sample_rate_hz.

51419b7efc Add support for transmitting/receiving from stdin/stdout
When '-' is used for filename, write samples to stdout when receiving or
read samples from stdin when transmitting. This allows using
hackrf_transfer in shell pipes with tools like csdr.
User info messages are written to stderr.

fed60c571c Update hackrf_transfer.c
Intro:
Some of the Hackrf board use a bad performance crystal, it will cause some program can't work---such as GNSS(GPS) simulation.  Most GPS receiver can capture the satellite
when the doppler within 10KHz, but 10ppm bias of the crystal will cause  15Khz doppler.  And my hackrf board uses a 16ppm crystal :(  normal
Of course, I can replace the crystal or use a external clock. But for most people, add a ppm correct function to hackrf_transfer is useful.
How to use:
1, measure your crystal's error
You can use a precision  counter to measure it.
Connect the hackrf's "clock out" to the counter, get the frequency Fh, then ,
ppm = (Fh - 10000000)/10 
 
You can use a standard clock source such as OCXO, TCXO, or Atom Clock, and a counter
to measure the crystal error too.

2, add an argument "-C ppm " when you use hackrf_transfer.

Eg. , your  crystal error is -8ppm ( In other words , your clock is slower than the standard clock), then you should add "-C -8" follow the hackrf_transfer command.

Hope you can understand my poor English:)
