vppinfra: minor tweaks for cgo interoperation

'type' is a keyword in golang, so s/type/event_type/ in elog.h and
elsewhere.

Add vec_len_not_inline(...), elog_write_file_not_inline(...) and
elog_read_file_not_inline(...) since the inline forms aren't usable.

More such tweaks may follow.

Type: improvement
