kib 623bffc363 Provide npx_get_fsave(9) and npx_set_fsave(9) functions to obtain and ... restore the FPU state from the format of machine FSAVE area. The intended use is for ABI emulators to provide FSAVE-formatted FPU state to usermode requiring it, while kernel could use FXSAVE due to XMM/XSAVE. The core functionality to convert from/to FXSAVE format is shared with the fill_fpregs_xmm() and set_fpregs_xmm(). Move the later functions to npx.c and rename them to npx_fill_fpregs_xmm() and npx_set_fpregs_xmm(). They differ from nptx_get/set_fsave(9) since our mcontext contains padding to be zeroed or ignored. fill_fpregs() and set_fpregs() could be converted to use the new interface, but there are small differences to handle.
