- pointers not initialized by ext2fs_get_mem()
- return without value in non-void function
- dereferencing type-punned pointers
- unused variables

The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and
this was starting to cause some tools heartburn. It also made "make
V=1" almost useless, since trying to following the individual commands
run by make was lost in the noise of all of the defines.
So fix this by putting the configure-generated defines in lib/config.h
and the directory pathnames to lib/dirpaths.h.
In addition, clean up some vestigal defines in configure.in and in the
Makefiles to further shorten the cc command lines.

This commit adds support for exporting filesystem into QCOW2 image
format. Like sparse format this saves space, by writing only necessary
(metadata blocks) into image. Unlike sparse image, QCOW2 image is NOT
sparse, hence does not change its size by copying with not-sparse-aware
tools.
New options '-Q' has been added to tell the e2image to use QCOW2 as an
output image format. QCOW2 supports encryption and compression, however
e2image so far does no support such features, however you can still
scramble filenames with '-s' option.
