Add snap packaging support
This commit adds a snapcraft.yaml file to allow lz4
to be distributed as a snap (see https://snapcraft.io/
for more info on snaps).
Building the Snap
-----------------
To build the snap simply install snapcraft and build the
snap e.g. on Ubuntu by doing:
$ sudo apt install snapcraft
$ cd contrib; snapcraft
This will build a snap that can be published [1] to
e.g. https://snapcraft.io/lz4
If you want to test the snap before publishing you
can do:
$ snap install <snapname>.snap --dangerous
And that will install it on your local host. You
will then have lz4 as a command to run.
Installing the Snap
-------------------
Once published and released in the snapstore your snap
can be installed on any platform that supports snaps
by doing:
snap install lz4

Don't Attach Very Small Dictionaries
Fixes a mismatch in behavior between loading into the context (via
`LZ4_loadDict()`) a very small (<= 4 bytes) non-contiguous dictionary, versus
attaching it with `LZ4_attach_dictionary()`.
Before this patch, this divergence could be reproduced by running
```
make -C tests fuzzer MOREFLAGS="-m32"
tests/fuzzer -v -s1239 -t3146
```
Making sure these two paths behave exactly identically is an easy way to test
the correctness of the attach path, so it's desirable that this remain an
unpolluted, high signal test.

added a test for LZ4F_compressEnd()
which actively tries to make it write out of bound.
For this scenario to be possible,
it's necessary to set dstCapacity < LZ4F_compressBound()
When a compression operation fails,
the CCtx context is left in an undefined state,
therefore compression cannot resume.
As a consequence :
- round trip tests must be aborted, since there is nothing valid to decompress
- most users avoid this situation, by ensuring that dstCapacity >= LZ4F_compressBound()
For these reasons, this use case was poorly tested up to now.
