Message : New feature: "Large Window Brotli" (#640) * New feature: "Large Window Brotli" By setting special encoder/decoder flag it is now possible to extend LZ-window up to 30 bits; though produced stream will not be RFC7932 compliant. Added new dictionary generator - "DSH". It combines speed of "Sieve" and quality of "DM". Plus utilities to prepare train corpora (remove unique strings). Improved compression ratio: now two sub-blocks could be stitched: the last copy command could be extended to span the next sub-block. Fixed compression ineffectiveness caused by floating numbers rounding and wrong cost heuristic. Other C changes: - combined / moved `context.h` to `common` - moved transforms to `common` - unified some aspects of code formatting - added an abstraction for encoder (static) dictionary - moved default allocator/deallocator functions to `common` brotli CLI: - window size is auto-adjusted if not specified explicitly Java: - added "eager" decoding both to JNI wrapper and pure decoder - huge speed-up of `DictionaryData` initialization * Add dictionaryless compressed dictionary * Fix `sources.lst` * Fix `sources.lst` and add a note that `libtool` is also required. * Update setup.py * Fix `EagerStreamTest` * Fix BUILD file * Add missing `libdivsufsort` dependency * Fix "unused parameter" warning.

.SS "#define BROTLI_BOOL   int"

.PP
A portable \fCbool\fP replacement\&. \fBBROTLI_BOOL\fP is a 'documentation' type: actually it is \fCint\fP, but in API it denotes a type, whose only values are \fBBROTLI_TRUE\fP and \fBBROTLI_FALSE\fP\&.
.PP
\fBBROTLI_BOOL\fP values passed to Brotli should either be \fBBROTLI_TRUE\fP or \fBBROTLI_FALSE\fP, or be a result of \fBTO_BROTLI_BOOL\fP macros\&.
.PP
\fBBROTLI_BOOL\fP values returned by Brotli should not be tested for equality with \fCtrue\fP, \fCfalse\fP, \fBBROTLI_TRUE\fP, \fBBROTLI_FALSE\fP, but rather should be evaluated, for example:
.PP
.nf
if (SomeBrotliFunction(encoder, BROTLI_TRUE) &&
    !OtherBrotliFunction(decoder, BROTLI_FALSE)) {
  bool x = !!YetAnotherBrotliFunction(encoder, TO_BROLTI_BOOL(2 * 2 == 4));
  DoSomething(x);
}

.fi
.PP
 
.SS "#define BROTLI_FALSE   0"

.PP
Portable \fCfalse\fP replacement\&. 
.SS "#define BROTLI_TRUE   1"

.PP
Portable \fCtrue\fP replacement\&. 
.SS "#define TO_BROTLI_BOOL(X)   (!!(X) ? \fBBROTLI_TRUE\fP : \fBBROTLI_FALSE\fP)"
