For a C implementation, it could interesting to consider LZ4 algorithm, since
it is written natively in this language. In contrast, Snappy has been ported
to C by Andy from the original C++ Google code, which lso translate into
less extensive usage and tests.

Furthermode, LZ4 license is BSD. And it has been reported in several tests
as being faster than Snappy/LZO, especially on decompression speed.

And last point, there is a "high compression" mode, which could be useful
for data rarely written/modified but often read.
