Theodore Ts'o d1154eb460 Shorten compile commands run by the build system
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.

Eric Sandeen 9e30fb23ef e2fsprogs: annotate intentional fallthroughs in case statements
Using the /* fallthrough */ comment lets Coverity (and humans)
know that we really do want to fall through in these case statements.

Theodore Ts'o 543547a52a libe2p, libext2fs: Update file copyright permission states to match COPYING
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.

Theodore Ts'o f77704e416 Add directory hashed signed/unsigned hint to superblock
The e2fsprogs and kernel implementation of directory hash tree has a
bug which causes the implementation to be dependent on whether
characters are signed or unsigned.  Platforms such as the PowerPC,
Arm, and S/390 have signed characters by default, which means that
hash directories on those systems are incompatible with hash
directories on other systems, such as the x86.

To fix this we add a new flags field to the superblock, and define two
new bits in that field to indicate whether or not the directory should
be signed or unsigned.  If the bits are not set, e2fsck and fixed
kernels will set them to the signed/unsigned value of the currently
running platform, and then respect those bits when calculating the
directory hash.  This allows compatibility with current filesystems,
as well as allowing cross-architectural compatibility.

Addresses Debian Bug: #389772

Theodore Ts'o b33278c4d6 Modify the half MD4 hash so it is no longer endian dependent. This is
a backwards incompatible change, but this should be OK since the kernel
MD4 ext3 code was only in the CVS tree, and hasn't generally escaped.

Add support for the TEA hash.

Theodore Ts'o cc90bdfd08 dirhash.c (ext2fs_dirhash): Fix bug which caused MD4
calculations for names > 32 characters to be completely
	bogus.  Changed MD4 calculation to match what is currently
	being used in the CVS gkernel tree.
