src: add dynamic register allocation infrastructure
Starting Linux kernel 5.18-rc, operations on registers that already
contain the expected data are turned into noop.
Track operation on registers to use the same register through
nftnl_reg_get(). This patch introduces an LRU eviction strategy when all
the registers are in used.
nftnl_reg_get_scratch() is used to allocate a register as scratchpad
area: no tracking is performed in this case, although register eviction
might occur.
