    Add 'i_bitdepth' to x264_param_t with the corresponding '--output-depth' CLI
    option to set the bit depth at runtime.
    
    Drop the 'x264_bit_depth' global variable. Rather than hardcoding it to an
    incorrect value, it's preferable to induce a linking failure. If applications
    relies on this symbol this will make it more obvious where the problem is.
    
    Add Makefile rules that compiles modules with different bit depths. Assembly
    on x86 is prefixed with the 'private_prefix' define, while all other archs
    modify their function prefix internally.
    
    Templatize the main C library, x86/x86_64 assembly, ARM assembly, AARCH64
    assembly, PowerPC assembly, and MIPS assembly.
    
    The depth and cache CLI filters heavily depend on bit depth size, so they
    need to be duplicated for each value. This means having to rename these
    filters, and adjust the callers to use the right version.
    
    Unfortunately the threaded input CLI module inherits a common.h dependency
    (input/frame -> common/threadpool -> common/frame -> common/common) which
    is extremely complicated to address in a sensible way. Instead duplicate
    the module and select the appropriate one at run time.
    
    Each bitdepth needs different checkasm compilation rules, so split the main
    checkasm target into two executables.
