ossfuzz: moving towards the ideal integration

Browse source 
- Start with the basic code from the ossfuzz project.
- Rewrite fuzz corpora to be binary files full of Type-Length-Value
  data, and write a glue layer in the fuzzing function to convert
  corpora into CURL options.
- Have supporting functions to generate corpora from existing tests
- Integrate with Makefile.am

==========
The goal is to add tests for *ALL* protocols supported in libcurl.
We will need some additional patches in the future, to increase coverage.
Building the fuzz target
========================
From the CURL root directory:
CC=clang-5.0 CFLAGS="-fsanitize=address -fsanitize-address-use-after-scope -fsanitize-coverage=trace-pc-guard,trace-cmp" ./configure --disable-shared --enable-debug --enable-maintainer-mode
export CC=clang-5.0
export CFLAGS="-fsanitize=address -fsanitize-address-use-after-scope -fsanitize-coverage=trace-pc-guard,trace-cmp"
./configure --disable-shared --enable-debug --enable-maintainer-mode
make -sj
cd tests/fuzz
make
(optional) export LIB_FUZZING_ENGINE=<path to libFuzzer.a>
make check
