Max Dymond 57001ce3bb ossfuzz: Move to C++ for curl_fuzzer.
Automake gets confused if you want to use C++ static libraries with C
code - basically we need to involve the clang++ linker. The easiest way
of achieving this is to rename the C code as C++ code. This gets us a
bit further along the path and ought to be compatible with Google's
version of clang.

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