This commit addresses two related issues: tsvector_filter() assumed it could print an incorrect weight value with %c. This could result in an invalidly-encoded error message if the database encoding is multibyte and the char value has its high bit set. Weight values that are ASCII control characters could render illegibly too. Fix by printing such values in octal (\ooo), similarly to how charout() would render them. tsvector_setweight() and tsvector_setweight_by_filter() reported the same unrecognized-weight error condition with elog(), as though it were an internal error. That'd not translate, would produce an unwanted XX000 SQLSTATE code, and also reported the bad value as a decimal integer which seems unhelpful. Fix by refactoring so that all three functions share one copy of the code that interprets a weight argument. The invalid-encoding aspect seems to me (tgl) to justify back-patching.
