Updated autoconf and automake options for tpl

[DaemonDave]

Hello;

Thank you for documenting your source code enough so a neophyte could use it. And clear testing. I can't tell you how much time protobuf-c cost me. It is appreciated that you took the time.
I normally update things when I find them and learn them, I improved your autoconf to include library version and some other changes. There might be some tweaking needed for windows, I only tried it on ubuntu. And win/malloc.c and realloc.c might have been toasted in the dist changes. You can uprev the library now.
libtpl-1.4.tar.gz
I don't want to generate a change to your source unless you want the changes. Attached is your tpl-master with update autoconfigure options .

Thanks again,

Dave

I know this comes 1.5 years late but I appreciate your input. The situation is unfortunately that I have zero time to review changes to tpl, especially if it involves any multi platform testing. As I cannot do this any time in the foreseeable future I will have to leave the issue as is.
