Various issues #75

bench.c:
* Before line 308, there should be a `free(chunkP);`.

fullbench.c:
* Before line 329, there should be a `free(chunkP);`.

lz4c.c:
* On lines 410 and 549, a less-than-zero check is done on an unsigned integer.
* The `if (errorcode)` checks on lines 374 and 519 are unnecessary because 
get_fileHandle() always returns 0.

Hi Brian

Thanks, quite a thorough investigation :)
It happens that some of these corrections were already completed into latest 
rc, but you nonetheless managed to find more of them.

Yes, this will be corrected.

You'll find in attached file a proposed rc,
which should correct all the points mentioned in this issue.

FWIW cppcheck[1] is the one that found these issues :-)

With the lz4rc.zip provided, the following issues (still) exist:

bench.c:
* Before line 347, there should be a `free(chunkP);`.

fullbench.c:
* Before line 368, there should be a `free(chunkP);`.

lz4c:
* Before line 642, there should be a `free(headerBuffer);`.
* On line 365, a less-than-zero check is done on an unsigned integer.
* The `if (errorcode)` checks on line 340 is unnecessary because 
get_fileHandle() always returns 0.

The following rc seems to successfully pass cppCheck
(excluding style-related warnings)
