NOTE: This commit only tested on Linux (Ubuntu 18.04). Windows
build may not work as expected.
* Use meson >= 0.47.0 cause we use install_man function
* Add three helper Python script:
* CopyFile.py: To copy file
* CreateSymlink.py: To make symlink (both Windows and Unix)
* GetZstdLibraryVersion.py: Parse lib/zstd.h to get zstd version
These help emulating equivalent functions in CMake and Makefile.
* Use subdir from meson to split meson.build
* Add contrib build
* Fix other build
* Add new build options
* build_programs: Enable programs build
* build_contrib: Enable contrib build
* build_tests: Enable tests build
* use_static_runtime: Link to static run-time libraries on MSVC
* zlib_support: Enable zlib support
* lzma_support: Enable lzma support
used absolute paths which are deprecated in meson, also missing some sources
that got split
also move source files each to their own line so future diffs are clearer.
