[PATCH 0/1] Add lz4 (C implementation)

[Leo Famulari]

This patch adds the C reference implementation of the lz4 compression
algorithm.

I'm looking for advice regarding the tests. The tests take >30 minutes on my on
my quad-core i5 with 8 gigabytes of RAM and they require Valgrind as a
native-input. This seems excessive to me but if users install binary
substitutes, they won't run the tests or need to install Valgrind, right? And 
if distributions won't test software, then who will?

It might be possible to cherry-pick which tests are used. `make test` is a
recursive call to a Makefile in the programs/ subdirectory of the tarball. That
Makefile builds the lists of test to run. For this reason, setting
'test-target' in the package definition won't work because it works on the 
top-level Makefile. If someone knows how to specify the test-targets on the 
second Makefile, we could ask upstream for advice on what tests to exclude.

Also, I have sent a message to the lz4 author asking if tests are expected to
fail when run in parallel. I expect the answer is yes, but I'd like to be sure.
