deduplicate_call_seq has a bug that skips call-seq for methods where the
alias is a prefix of the method name. For example, if the alias name is
"each" and the current method name is "each_line", then
deduplicate_call_seq will skip all call-seq for "each_line" since it
will believe that it is for the alias.

This change fixes alias call-seq to return nil if the method's
call-seq does not specify the alias.

Previously, the alias's call-seq would be an empty string in this case
which broke darkfish rendering.

This change also backfills test coverage for 0ead786 which moved
call-seq deduplication into AnyMethod.

Previously, only calls to rb_define_alias were treated as aliases.
This treats calls to rb_define_method with the same C function as
aliases, with the first function defined being the primary method.

This move the dedup code from the C parser to AnyMethod, and has
AnyMethod look in its aliases to find the call_seq.

Switch the deduplication code to remove lines matching one of the
other aliases, instead of only keeping lines matching the current
alias.  The previous approach could eliminate all call_seq lines
in cases where no line matched.  This was necessary to pass
tests when call_seq does deduplication by default.

The only change to the darkfish template is to not perform
unnecessary work by deduplicating twice.
