Use in-memory buffers instead of temporary files. This avoids
the need for low-level I/O on the FD returned by g_mkstemp().
Refactor the code accordingly. Also plug a number of leaks and
tighten the error checking.
This fixes parts of bug #423.

Since Autoconf places some important feature flags only into the
configuration header, it is necessary to include it globally to
guarantee a consistent build.
A few of these were pretty serious, like missing arguments,
passing integers where a string was expected, and so on.
In some places, change the types used by the code rather than
just the format strings.
Move the include flags for files in the source tree from
configure.ac to Makefile.am where they belong. Also use
AM_CPPFLAGS instead of CFLAGS/CXXFLAGS to make sure the
files in the build/source tree are always picked up first.
Also, remove the include/libsigrok sub-directory from the
search path, thereby making the <libsigrok/> prefix mandatory
when building libsigrok itself. This matches the convention
already imposed on users of the library.
Gnuplot doesn't have any "official" file name extension(s). It uses
(at least) two different types of files basically:
- "control files": These can have many different somewhat commonly
used extensions such as .gpi, .gnu, .gnuplot, .gp, .plt, .gih,
others. These files don't contain data, only Gnuplot commands such
as 'set yrange [75:105]', 'set ylabel "foo" offset 1', and so on.
- "data files": This is what libsigrok reads and writes. These files
contain actual data to be graphed by Gnuplot (with the help of a
specially-crafted control file, see above). The data is usually in
a tab-separated format. The common file extension is usually .dat,
though many others are possible as well.
- 'struct sr_input *' variables are consistently named 'in'.
- 'struct sr_input_module *' variables are consistently named 'imod'.
- 'struct sr_output *' variables are consistently named 'o'.
- 'struct sr_output_module *' variables are consistently named 'omod'.
Use g_malloc0() for small allocations and assume they always
succeed. Simplify error handling in a few places accordingly.
Don't always sanity-check parameters for non-public (SR_PRIV)
functions, we require the developers to invoke them correctly.
This allows further error handling simplifications.
This is a feature restricted to the new analog struct.
By default all the digits available in the encoding struct are printed.
The option "digits", when set to "spec", changes this to print the
number given in the spec struct.
The automatic selections of the measured quantity and equivalent circuit
model are more part of the configuration of the meter than attributes
of the measurement result. To reflect this, model them as config keys
instead of mqflags. This allows a driver that supports remote control to
implement 'set' method for them and has the additional benefit of saveing
two flag bits.
