build-sys: add temporary libtool *.m4 stuff

We require libtool-2 (because old 1.5.x is crap). Unfortunately,
libtool-2 is still not available in many Linux distributions  -- now I
see it in unstable distributions only. The painless way how to resolve

after checkout from git repository.

blkid: start to use ABI versioning

The library ABI and API is backwardly compatible, so it does not
make sense to change the library SONAME. This patch adds a symbol
versioning, naming paradigm is:

BLKID_<maj>.<min>

The original libblkid from e2fsprogs uses "1.0" as a .so version and
"libblkid.1" as a SONAME for all time (at least according to stuff in
/lib/libblkid*)

And the original library is without symbols versioning. It means that
many private functions are exported to applications ;-(

Note that the original blkid_get_library_version() returns
E2FSPROGS_VERSION. The version in util-linux-ng returns BLKID_VERSION
which is <maj>.<min>.<rel>. The <maj>.<min> is the same version as we
use for ABI. This concept seems less confusing than mix a library
version and package version.

Summary:

OLD (e2fsprogs):
  ABI versioning:              -none-
  SONAME:                      libblkid.1
  .so version:                 libblkid.so.1.0
  blkid_get_library_version(): @E2FSPROGS_VERSION@ (e.g. 1.41.1)

NEW (util-linux-ng):
  ABI versioning:              BLKID_<maj>.<min>
  SONAME:                      libblkid.1
  .so version:                 libblkid.so.<maj.<min> (e.g. 1.41)
  blkid_get_library_version(): @BLKID_VERSION@ (e.g. 1.41.1)

  (BLKID_VERSION = <maj>.<min>.<rel>)

The function blkid_do_probe() is able to detect more filesystems on

while(blkid_do_probe(pr) == 0)
...

but in many cases we need only one exact answer, and we also need to
be sure that there is not any other FS on the device.

For example it's possible to create valid LUKS (or vfat, ...) header
and valid linux swap header on the same device -- in such case the
device can be interpreted (by mount/swapon) in two completely
different ways. An ambivalent result is always error -- the library
never returns such result.
