dynamic_emit_prefix() currently separates modname, funcname, lineno
with ':'. This is complicates use of cut -d: <logfile>, since the
field positions can change per callsite with dynamic-debug. So change
inter-field separator to '.' and keep the ':' prefix terminator.
This improves the situation, but doesnt solve it entirely; if
dyndbg==p is used, the callsite is enabled but no prefix is added, so
theres one less ':' in the message. Changing the terminator to ','
would fix this, and might be warranted.
pr_fmt(fmt) KBUILD_MODNAME ": " fmt, also adds another ':'.
