I've had it with ICU always changing their ABI without updating the
SO numbers. They did that before, and they have done it with
51.1->51.2 again. !@#
(Will icu-project ever get their act together?)

Thus, we will use the full version as the SO identifier in openSUSE.

Details:

U_ICU_VERSION_SHORT was (example) "49" before when there was a
libicui18n.so.49. Now, since there is a libicui18n.so.51.2, we need to
change U_ICU_VERSION_SHORT. But the define's documentation says
"without dots", and I do not know how much downstream code depends on
the non-dot feature, if at all. Anyhow, to bypass this question to
which we have no definite answer, U_ICU_VERSION_SHORT is instead simply
defined to "51_2" and we "fix" (read like: hack) it with symlinks.

However, the ICU source also uses U_ICU_VERSION_SHORT to construct the
path to its data files. However, as there is no "icudt51_2l.dat", but
only a "icudt51l.dat", U_ICU_VERSION_MAJOR_STR is introduced for
ICU-internal use, so that I do not have to edit more dirty Makefiles to
produce a "icudt51_2l.dat" instead. In fact, placing the version number
in "icudt51l" seems redundant, since that file is in a version-specific
directory anyway (/usr/share/icu/51.2/) — another point where ICU
development seems to not pay enough attention.
