TurboJPEG: Update JPEG buf ptrs on comp/xform err
When using the in-memory destination manager, it is necessary to
explicitly call the destination manager's term_destination() method if
an error occurs. That method is called by jpeg_finish_compress() but
not by jpeg_abort_compress().
This fixes a potential double free() that could occur if tjCompress*()
or tjTransform() returned an error and the calling application tried to
clean up a JPEG buffer that was dynamically re-allocated by one of those
functions.

jchuff.c: Fix MSan error
Certain rare malformed input images can cause the Huffman encoder to
generate a value for nbits that corresponds to an uninitialized member
of the DC code table. The ramifications of this are minimal and would
basically amount to a different bogus JPEG image being generated from a
particular bogus input image.

OSS-Fuzz: Build fuzz targets using C++ compiler
Otherwise, the targets will require libstdc++, the i386 version of which
is not available in the OSS-Fuzz runtime environment. The OSS-Fuzz
build environment passes -stdlib:libc++ in the CXXFLAGS environment
variable in order to mitigate this issue, since the runtime environment
has the i386 version of libc++, but using that compiler flag requires
using the C++ compiler.
