This patch bumps current serial file version from the Autoconf Archive
from 6 to 8.
Changes:
- simplified and more permissive license
- https links in the file comments
The symbol was being set up in cmake but not on the autotools side.
Clean this up to be like other external libraries.
We need to pull in some openmp logic as it's not uncommon for the lib
to be built with openmp support. When we test for it, we need to do
so with openmp flags.
Fixes#137.
`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.
