cmake refactor Refactors many things in cmake to improve and simplify: - don't use variable indirection for target names; target names are *already* a variable of sorts. (e.g. ${UTIL_LIB} is now just lokinet-util). cmake/basic_definitions.cmake is now gone. - fix LTO enabling to use the standard cmake (3.9+) LTO mechanism rather than shoving a bunch of flag hacks through link_libraries and add_compile_options. This also now enables LTO when building a shared library (because previously the -flto hacks were only turned on in the static code for some reason). - build liblokinet as *either* shared library or static library, but not both. Building both makes things more complicated because they had different names (lokinet-shared or lokinet-static) and seems pointless: you generally want one or the other. Now there is just the liblokinet target, which will be shared or static depending on the value of BUILD_SHARED_LIBS. - Simplify lokinet-cryptography AVX2 code: just build *one* library, and add in the additional AVX2 files when possible, rather than building two and needing to merge them. - Compress STATIC_LINK and STATIC_LINK_RUNTIME into just STATIC_LINK. It makes no sense to use one of these (_RUNTIME) on Windows and the other on non-Windows when they appear to try to do the same thing. - remove a bunch of annotations from `endif(FOO)` -> `endif()`. - move all the tuntap compilation code (including OS-specific source file selection) into vendor/CMakeLists.txt and build tuntap as an intermediate OBJECT library rather than keeping a global variable in 5 different files. - move release motto define to root cmake; it made no sense being duplicated in both unix.cmake and win32.cmake - fix add_log_tag to not stomp on any existing source compile flags with its definition. Also use proper compile definition property instead of cramming it into compile flags. - make optimization/linker flags less hacky. There's no reason for us to force particular optimization flags because the cmake build type already does that (e.g. -DCMAKE_BUILD_TYPE=Release does -O3). Not doing that also silences a bunch of cmake warnings because it thinks "-O0 -g3" etc. are link libraries (which is reasonable: that's what the code was telling cmake they are). - sets the default build type to RelWithDebInfo which gives us `-O2 -g` if you don't specify a build type. - Move PIC up (so that the things loaded in unix.cmake, notably libuv, have it set). - Add a custom `curl` interface library that carries the correct link target and include paths for curl (system or bundled).
