Previously STOW_DIR=0 would cause the cwd to be used as the STOW_DIR.
Make that instead raise an error. Do similar validation on the target
directory.
Closes#7 - https://github.com/aspiers/stow/pull/7
In shell, a variable is often considered unset even if it is
set to the empty string. In other words,
STOW_DIR= stow [args]
is an idiomatic alternative to writing:
unset STOW_DIR
stow [args]
and it also has the advantage of temporarily "unsetting" STOW_DIR
for a single command.
Therefore we should treat STOW_DIR being set to the empty string
as equivalent to it not being set at all.
Thanks to Cuong Manh Le for highlighting this issue!

This is now necessary in order to prevent pause.perl.org from
complaining:
Status: Decreasing version number
=================================
module : Stow::Util
version: undef
in file: lib/Stow/Util.pm
status : Not indexed because lib/Stow/Util.pm in
A/AS/ASPIERS/Stow-v2.2.0.tar.gz has a higher version number
(0)
The dependency of the distributed file stow.8 on the non-distributed
file Makefile was causing this error:
ERROR: files left in build directory after distclean:
./doc/stow.8
The automake FAQ explains why this happens:
https://www.gnu.org/software/automake/manual/html_node/Errors-with-distclean.html
so change stow.8 to depend on Makefile.am which is distributed.
With Perl 5.20, installing a package with stow gives a warning like
this:
Possible precedence issue with control flow operator at
/gar/packages/stow-2.2.0/lib/perl5/site_perl/5.20.0/Stow.pm line 1736.

Fix the case discovered by Hiroyuki Iwatsuki where stowing fails if
the stow / target directories are non-canonical paths. For example,
on FreeBSD /home is a symlink pointing to 'usr/home', so running with
the stow directory as /home/user/local/stow and the target directory
as /home/user/local previously resulted in the stow directory path
being calculated as ../../../usr/home/user/local/stow relative to
the target.
