vlib: stop inlining vlib_add_trace(...)
Packet tracing performance doesn't justify inlining
vlib_add_trace(...) over 500 times.
It makes a 15% text-segment size difference in a representative use-case:
Inline:
$ size .../vnet_skx.dir/ipsec/ipsec_input.c.o
text data bss dec hex filename
6831 80 0 6911 1aff .../vnet_skx.dir/ipsec/ipsec_input.c.o
Not inline:
$ size .../vnet_skx.dir/ipsec/ipsec_input.c.o
text data bss dec hex filename
5776 80 0 5856 16e0 .../vnet_skx.dir/ipsec/ipsec_input.c.o
Retain the original code as vlib_add_trace_inline, instantiate once as
vlib_add_trace.
Type: refactor
