Fix build with autotools.

`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.
