When using autotools to build the binary and libraries, the resulting libraries don't link `brotlicommon` or `m`.
This was detected when building cURL 7.57.0 which has now has brotli support. During configure it was failing
```
checking run-time libs availability... failed
configure: error: one or more libs available at link-time are not available run-time. Libs used at link-time: -lbrotlidec -lz -L/usr/local/lib
```
inspection of config.log showed missing symbols from libbrotlicommon as the cause.

This patch results in the encryption and decryption libs to be properly linked against libbrotlicommon and libm.

* add autotools build
* separate semantic and ABI version
* extract sources.lst (used by CMake and Automake)
* share pkgconfig templates (used by CMake and Automake)
* decoder: always set `total_out`
* encoder: fix `BROTLI_ENSURE_CAPACITY` macro (no-op after preprocessor)
* decoder/encoder: refine `free_func` contract
