This fuzz target handles .xz stream encoding. The first byte of input
is used to dynamically set the preset level in order to increase the
fuzz coverage of complex critical code paths.
This fuzz target that handles LZMA alone decoding. A new fuzz
dictionary .dict was also created with common LZMA header values to
help speed up the discovery of valid headers.
All .c files can be built as separate fuzz targets. This simplifies
the Makefile by allowing us to use wildcards instead of having a
Makefile target for each fuzz target.
