Steve Markgraf 81833a1cf6 lib: disable usbfs zero-copy support by default
Although we added a detection mechanism for the presence of the Kernel
bug earlier, reading from the incorrectly mapped memory might cause a
bus error on some ARM systems.

With the overall performance benefit being rather minimal for the
data rates of rtl-sdr, disable zero-copy by default.

Steve Markgraf 3e17ef2b55 lib: don't detach kernel driver by default
Since this feature also disconnects running instances
of librtlsdr that claimed the device, it is now disabled
by default and can only be enabled at compile time.

To enable it when building with cmake:

To enable it when building with automake:
./configure --enable-driver-detach

Christian Vogel 3087e7acde Replace obsolete automake AM_CONFIG_HEADER.
This fixes the following complaint by autoconf 2.69-1, automake 1.13.1-1.

: error: 'AM_CONFIG_HEADER': this macro is obsolete.
: You should use the 'AC_CONFIG_HEADERS' macro instead.
: /usr/share/aclocal-1.13/obsolete-err.m4:12: AM_CONFIG_HEADER is expan
: the top level

Automake 1:1.11.3-1ubuntu2, autoconf 2.68-1ubuntu2 don't even emit a warning
without, and work just fine with this patch.

Kyle Keen 995a195f4d rtl_test: add ppm measurement
Use with caution, the result highly depends on the
accuracy of the clocksource your machine uses.
On some machines it may be quite accurate, on
others completely off.
