In backtrace.h spice_backtrace is defined as:
#if defined(WIN32) && !defined(__MINGW32__)
#define spice_backtrace()
#else
..
so don't try to compile if an empty macro is used.
Currently not causing any issue as we use MingW on Windows but
does not hurt is code is more portable.

This should always be defined and including config.h is a requirement.

Most users of spice_common.h don't need it, or only need log.h. It only
has a few users outside of spice-common. It's not very well defined
which headers it should contain. This commit removes spice_common.h in
favour of direct inclusion of the needed headers.

We are mostly likely not running as root, so this call will fail. As we are
supposed to check its return value as it's declared with
warn_unused_result, the current way of using it is wrong, so this commit just
removes the call.
Be more library friendly, by not aborting in library errors.
spice_common now includes a proper log handler that will abort by
default when reaching a warning.
SPICE_ABORT_LEVEL can be changed to modify run-time abort level.
SPICE_DEBUG_LEVEL can be changed to be more verbose. By default, only
log level more importants than WARNING.
Only memory-related functions are allowed to abort(), since they are
not recoverable errors in the library.
Add a backtrace printing function copied from xserver os/backtrace.c
that uses gstack, and if that isn't found then glibc's backtrace.
Used in ASSERT, tested on F15.
