small extDict : fixed side-effect
...
don't fix dictionaries of size 0.
setting dictEnd == source triggers prefix mode,
thus removing possibility to use CDict.

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.

added dictID inside LZ4F_frameInfo_t

Compressor can set dictID on LZ4F_compressBegin()
Decompressor can retrieve it using LZ4F_getFrameInfo()

Safer LZ4_getFrameInfo()
