c1c76e993f Don't check cur_ix_masked against ring_buffer_mask. 
`cur_ix_masked` isn't changing from iteration to iteration, and `max_length` ensures we never find a match long enough to walk off the ring buffer.

9351fa7ffb Compare 4 bytes when checking if a longer match is possible. 
Loading and comparing 4 bytes is ~as fast as 1 byte, but allows us to avoid more full match length calculation.

3ebb2d30ab Move serialized dictionary feature behind the flag. 
BROTLI_SHARED_DICTIONARY_SERIALIZED enum value is a part of API,
but it should not be used (will cause failures).
Changing how serialized dictionaries work won't be considered as an API change, until this feature is enabled.
Enabling this feature in the future will be considered as a "compatible" change.

CMake: Allow using BUILD_SHARED_LIBS to choose static/shared libs (#655) 
By convention projects using CMake which can build either static or
shared libraries use a BUILD_SHARED_LIBS flag to allow selecting between
both: the add_library() command automatically switches between both using
this variable when the library kind is not passed to add_library(). It
is also usual to expose the BUILD_SHARED_LIBS as an user-facing setting
with the option() command.

This way, the following will both work as expected:

   % cmake -DBUILD_SHARED_LIBS=OFF ...
   % cmake -DBUILS_SHARED_LIBS=ON ...

This is helpful for distributions which need (or want) to build only
static libraries.
