1ae38772df restored cmake build tests in Travis 
for some reason, these tests were no longer played on Travis.

As a consequence, I discovered some left-over from the util.c change while testing.

f0fe9b0f02 Reverted removal of a trailing space. 
My editor removes trailing spaces while saving. Not confusing things I
reverted that change.

c7942caff0 Clarify special case of offset history update 
If the current sequence has literal length of zero then an offset value
of three is handled in a special manner. While I implemented a golang
decoder I had to consult the educational decoder for clarification on
the update of the offset history in that case. This commit provides the
clarification that the offset value Repeated_Offset1-1 is handled as a
new offset is added to the offset history accordingly.

f181799082 fix decodecorpus incorrect frame generation 
fix #1379
decodecorpus was generating one extraneous byte when `nbSeq==0`.
This is disallowed by the specification.

The reference decoder was just skipping the extraneous byte.
It is now stricter, and flag such situation as an error.

Improved decompression speed
 2018-10-10 19:16:35 -07:00
Yann Collet
6ed3b526e4 restored bitMask for shift values 
since corrupted bitstreams can generate too large values.

This slightly reduces the benefits from clang on my laptop.
gcc results and code generation are not affected.

433059bbb2 fixed minor gcc warning 
gcc-8 on Linux doesn't like usage of strncat :
`warning: ‘strncat’ output truncated before terminating nul copying as many bytes from a string as its length`.

Not sure what was wrong, it might be a false positive,
but the logic is simple enough to replaced by a simple `memcpy()`,
thus avoiding the shenanigans of null-terminated strings.

d3ec23313d improved decompression speed 
while reviewing #1364,
I found a decompression speed improvement.

On my laptop, the new code decompresses +5-6% faster on clang
and +2-3% faster on gcc.

not bad for an accidental optimization...
