We've been shipping the pkg-config file for a while now and
want people to use that only, so drop this old script.
This also drop the FEATURES variable as it was only available
via `gdlib-config --features` (and no one has complained).
`configure.ac` and `bootstrap.sh` are moved in the top directory.
`bootstrap.sh` is completed to execute `libtoolize`. The list of files
to clean is reduced. Other files can be cleaned with `make distclean`.
`src/Makefile.am` is fixed for missing `gd_nnquant.c` dependency.
`ACX_PTHREAD` macro is moved to a `m4` directory to make `configure.ac`
easier to read.
