- Remove googletest-devel BuildRequires and pzstd-global-gtest.patch
because we want zstd in ring0 (due to rpm's zstd payload support)
Since googletest is only used in build time (it's for testing after
all), this should be fine.

* cli: added --[no-]compress-literals flag to enable or disable
literal compression

because 603MB/s (lowest zstd level) is not "real-time" for
quite some applications.
* Sat Jan 5 2019 astieger@suse.com

* better decompression speed on large files (+7%%) and cold
dictionaries (+15%%)

%description
Zstd, short for Zstandard, is a lossless compression algorithm. Speed
vs. compression trade-off is configurable in small increments.
Decompression speed is preserved and remains roughly the same at all
settings, a property shared by most LZ compression algorithms, such
as zlib or lzma.
At roughly the same ratio, zstd (v1.4.0) achieves ~870%% faster
compression than gzip. For roughly the same time, zstd achives a
~12%% better ratio than gzip. LZMA outperforms zstd by ~10%% faster
compression for same ratio, or ~1–4%% size reduction for same time.

%package -n %{libname}
Summary: Zstd compression library
Group: System/Libraries
%description -n %{libname}
Zstd, short for Zstandard, is a lossless compression algorithm,
targeting faster compression than zlib at comparable ratios.
This subpackage contains the implementation as a shared library.
