af12733467 fixed frametest error
The error can be reproduced using following command :
./frametest -v -i100000000 -s1659 -t31096808

It's actually a bug in the stream LZ4 API,
when starting a new stream
and providing a first chunk to complete with size < MINMATCH.
In which case, the chunk becomes a dictionary.
No hash was generated and stored,
but the chunk is accessible as default position 0 points to dictStart,
and position 0 is still within MAX_DISTANCE.
Then, next attempt to read 32-bits from position 0 fails.

The issue would have been mitigated by starting from index 64 KB,
effectively eliminating position 0 as too far away.

The proper fix is to eliminate such "dictionary" as too small.
Which is what this patch does.

* Fix `mandir`

  always use the lower case variables.
* Add test case that ensures overriding both upper- and lower-case
  variables is the same, and that the directory is empty after uninstall.

ce4e1389cc fuzzer.c: enabled ring buffer tests for decompress_fast
Ring buffer tests were performed only with LZ4_decompress_safe_continue,
leaving my buggy changes to LZ4_decompress_safe_continue undetected.
The tests are now replicated and performed in a similar manner for both
LZ4_decompress_safe_continue and LZ4_decompress_safe_continue (except
for the small buffer case where only one function can be tested,
because part of the dictionary is overwritten with the output).

I also updated function names in the messages (changed them to the
actual ones).  The error was reported for LZ4_decompress_safe(),
which I found misleading.

5603d30f81 lz4.c: fixed the LZ4_decompress_safe_continue case
The previous change broke decoding with a ring buffer.  That's because
I didn't realize that the "double dictionary mode" was possible, i.e.
that the decoding routine can look both at the first part of the
dictionary passed as prefix and the second part passed via dictStart+dictSize.

So this change introduces the LZ4_decompress_safe_doubleDict helper,
which handles this "double dictionary" situation.  (This is a bit of
a misnomer, there is only one dictionary, but I can't think of a better
name, and perhaps the designation is not all too bad.)  The helper is
used only once, in LZ4_decompress_safe_continue, it should be inlined
with LZ4_FORCE_O2_GCC_PPC64LE attached to LZ4_decompress_safe_continue.

(Also, in the helper functions, I change the dictStart parameter type
to "const void*", to avoid a cast when calling helpers.  In the helpers,
the upcast to "BYTE*" is still required, for compatibility with C++.)

So this fixes the case of LZ4_decompress_safe_continue, and I'm
surprised by the fact that the fuzzer is now happy and does not detect
a similar problem with LZ4_decompress_fast_continue.  So before fixing
LZ4_decompress_fast_continue, the next logical step is to enhance
the fuzzer.

bb83cad98f Fix input size validation edge cases
The bug is a read up to 2 bytes past the end of the buffer.
There are three cases for this bug, one for each test case added.

* An empty input causes `token = *ip++` to read one byte too far.
* A one byte input with `(token >> ML_BITS) == RUN_MASK` causes
  one extra byte to be read without validation. This could be
  combined with the first bug to cause 2 extra bytes to be read.
* The case pointed out in issue #508, where `ip == iend` at the
  beginning of the loop after taking the shortcut.

Benchmarks show no regressions on clang or gcc-7 on both my mac
and devserver.

Fixes #508.

0ddd1ceb1d added target make check
according to GNU Makefile conventions,
the Makefile should feature a make check target
to self-test the generated program:
https://www.gnu.org/prep/standards/html_node/Standard-Targets.html .

this is much less thorough and less taxing than `make test`,
and can be run on any target in a reasonable timeframe (several seconds).
