revset: parse alias declaration strictly by _parsealiasdecl
Before this patch, alias declaration is parsed by string base
operations: matching against "^([^(]+)\(([^)]+)\)$" and splitting by
",".
This overlooks many syntax errors like below (see the previous patch
introducing "_parsealiasdecl" for detail):
- un-closed parenthesis causes being treated as "alias symbol"
- symbol/function name aren't examined whether they are valid or not
- invalid argument list causes unexpected argument names
To parse alias declaration strictly, this patch replaces parsing
implementation by "_parsealiasdecl".
This patch tests only one typical declaration error case, because
error detection itself is already tested in the doctest of
"_parsealiasdecl".
This also removes class property "args" and "error", because these are
certainly initialized in "revsetalias.__init__".
