Add CMake option LZ4_BUILD_CLI.
Defaults to ON so nothing changes, but it can be set to OFF so that the
CLI is not built at all, only the library.

b223f11b21 ubsan: make pointer overflow recoverable
the way `base` is used must allow 2-complement address overflow.
`base` is effectively a virtual pointer, never dereferenced directly.
What matters is `base + index`.
This is the address that will be dereference and must be valid (it is properly validated).

LZ4_decompress_safe_partial()
now also supports a scenario where
nb_bytes_to_generate is <= block_decompressed_size
And
nb_bytes_to_read is >= block_compressed_size.

Previously, the only supported scenario was
nb_bytes_to_read == block_compress_size.

Pay attention that,
if nb_bytes_to_read is > block_compressed_size,
then, necessarily, it requires that
nb_bytes_to_generate is <= block_decompress_size.
If both are larger, it will generate corrupted data.

9a7658070a Use fstat() to determine file size.
This allows us to get the file size even when the input file is passed
via stdin. This fixes `--content-size` not working in situations like

    $ lz4 -v --content-size < /tmp/test > /tmp/test.lz4
    Warning : cannot determine input content size

With this change, it works.

Also helps with #904.

0002563be8 removed LZ4_compress_fast_force()
which serves no more purpose.

The comment implies that the simple presence of this unused function was affecting performance,
and that's the reason why it was not removed earlier.
This is likely another side effect of instruction alignment.

It's obviously unreliable to rely on it in this way,
meaning that the impact will be different, positive of negative,
with any minor code change, and any minor compiler version change, even parameter change.
