    - Fix typo in OPUS_USE_NEON description.

    - Set OPUS_PRESUME_NEON for iOS platforms as all armv7 and higher
      iOS devices support NEON.

    - Fix detection of aarch64 for OPUS_CPU_ARM and adding sources from
      celt_sources_arm. (previously would miss armcpu.c and arm_celt_map.c)

    - Change "armv7-a" to "arm" in MATCHES checks against
      CMAKE_SYSTEM_PROCESSOR as systems like the RPi3 report as
      "armv7l".

    - Rename OPUS_MAY_SUPPORT_NEON to OPUS_MAY_HAVE_NEON as this name is
      used everywhere else in the CMake build system. Without this,
      runtime capability detection is broken on aarch64.

cmake - intinsics fixes, only compile SSE source with SSE flags on non-windows when target use runtime check (GH #154). For windows we only use /arch flag when target is presumed to support SSE to avoid AVX function pollution (GH #132).

Install include directory must be `include/opus`, not `include`.

Old path is still here for compatibility.

When using OPUS_CUSTOM, `CELTDecoder->end` can be larger than 21.
Assert against 25 instead in OPUS_CUSTOM builds.

Reland "Fixes to the the activity flag that is passed to Silk so it represents the final activity flag used in the DTX decision"

This flag was modified after calling the Silk encoder function. This commit corrects that behavior by introducing those modifications before calling the Silk encoder.

The old variable `OPUS_LIBRARY_VERSION`, does not line up with what's used in autoconf, which uses the PACKAGE_VERSION instead, which in turn lines up with what version the projects `opusfile` and `libsndfile` check for, for example.
While at it, I also cleaned up the accidental double up in code.

From https://cmake.org/cmake/help/latest/variable/BUILD_SHARED_LIBS.html:

"Global flag to cause add_library() to create shared libraries if on.

If present and true, this will cause all libraries to be built shared unless the library was explicitly added as a static library. This variable is often added to projects as an option() so that each user of a project can decide if they want to build the project using shared or static libraries."

Thanks to theislander on HA for reporting this.

If CMAKE_BUILD_TYPE is empty and CFlags are set then only use CFlags.
If None are set then use CMAKE_BUILD_TYPE by Release by default.
