added .gitignore, improved support for in-tree building

Here is how to run configure within the source tree:
$ rpm -bE --enable debug *.spec |sed -n '/^%build$/,/^%install$/{/^%build$/d;/^%install$/d;p}' |sh -ex

There's still problem: po/Makefile.in is getting added to
configure.ac:AC_OUTPUT, and when running autoreconf for the second time,
it will die as follows.

    autoreconf-default: running: aclocal -I m4 --force -I m4
    configure.in:896: error: `po/Makefile.in' is already registered with AC_CONFIG_FILES.
    ../../lib/autoconf/status.m4:290: AC_CONFIG_FILES is expanded from...
    configure.in:896: the top level
    autom4te-2.60: /usr/bin/m4 failed with exit status: 1
