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.

In inode_open(), if the allocation of &io fails, we go to cleanup
and dereference io to test io->name, which is a bug.
Similarly in undo_open() if allocation of &data fails, we
go to cleanup and dereference data to test data->real.
In the test_open() case we explicitly set retval to the only
possible error return from ext2fs_get_mem(), so remove that
for tidiness.
The other changes just make make earlier returns go through
the error goto for consistency.
In many cases we returned directly from the first error, but
"goto cleanup" etc for every subsequent error. In some
cases this leads to "impossible" tests such as:
if (ptr)
ext2fs_free_mem(&ptr)
on paths where ptr cannot be null because we would have
returned directly earlier, and Coverity flags this.
This isn't really indicative of an error in most cases, but
I think it can be clearer to always exit through the error goto
if it's used later in the function.

In the !undo_io_backing_manager case, undo_err_handler_init
will be passed a null data->real, which will be dereferenced.

The top-level COPYING file states that the e2p and ext2fs libraries
are available under the LGPLv2. The files were incorrectly labelled.
Alex Thomas/Luster has been consulted wrt to the ext3_extents.h file;
the rest of the files were primarily authored by Theodore Ts'o.

This I/O manager saves the contents of the location being overwritten
to a tdb database. This helps in undoing the changes done to the
file system.
