Unify 8-bit and 10-bit CLI and libraries
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.
