measures :
- compression ratio with / without dictionary
- create one dictionary per block
- memory budget for dictionaries
- decompression speed, using one different dictionary per block
current limitations :
- only one file
- 4K blocks only
- automatic dictionary built with 4K size
dictionary can be selected on command line, with -D

Add CXXFLAGS to ALL_LDFLAGS ( #1178 )
...
pzstd requires C++11, which older C++ standard libraries like libstdc++
as used on OS X 10.8 and earlier don't support. The user might address
this by setting "CXXFLAGS=-stdlib=libc++". This flag must be used both
at compile time and at link time. Asking the user to also put the flag
in LDFLAGS is undesirable because then the flag would also be used when
linking C code, which would be inappropriate.
