 add_subdirectory() command

We don't need to build the lz4 CLI tool, or anything else. We just want
to build in the library statically, so we specify this to ensure that.
Now, we don't potentially build unnecessary targets.

Subject: [PATCH 26/60] fsp_srv: Emplace entries first when building index
 instead of emplacing last

The current way were doing it would require copying a 768 character
buffer (part of the Entry struct) to the new element in the vector.
Given it's a plain array, std::move won't eliminate that.

Instead, we can emplace an instance directly into the destination buffer
and then fill it out, avoiding the need to perform any unnecessary
copies.

Given this is done in a loop, we can request the destination to allocate
all of the necessary memory ahead of time, avoiding the need to
potentially keep reallocating over and over on every few insertions into
the vector.

Given elements inserted into a vector are zeroed out, we can just copy
MAX_LEN - 1 elements and the data will already be properly null

Subject: [PATCH 46/60] gl_rasterizer_cache: Use std::vector::assign in
 LoadGLBuffer() for the non-tiled case

resize() causes the vector to expand and zero out the added members to
the vector, however we can avoid this zeroing by using assign().

Given we have the pointer to the data we want to copy, we can calculate
the end pointer and directly copy the range of data without the
need to perform the resize() beforehand.
