zip_append_analog() does not free most of the memory it allocates. Address
this by moving all sanity checks that do not rely on anything else at the
beginning of the function before any allocations are done. And then make
sure to properly free all allocated memory on all paths leaving the
function.

0 is a valid index for a channel. Using it as the value for the terminating
entry of analog_index_map causes zip_append_analog() to falsely assume that
no channel was found when a packet for a channel with index 0 was received.
This prevents the data for the channel to be added to the sigrok session
file.
Instead use -1, which is not a valid channel index, as
the terminating entry value.

- Don't set capturefile if no logic channels are saved
- Don't set total probes if no logic channels are saved
- Save analog channels without index gaps (e.g. probe1/probe4)
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.
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.
