Symbol tables with fewer than 128 entries, so everything can be
represented as a single byte, are not realistic.
Stuff the symbol table with fake entries before adding the real ones.

[ENHANCEMENT] Relabeling: small speed-up of hashmod
Code optimization: The relabel operation is used very frequently, and strconv.FormatInt() with better performance should be used.
This replaces the custom `moreThanOneRune` function with the standard
`utf8.DecodeRuneInString(s)` that can be used to figure out the size of
the first rune.

This adds some more test cases for unicode values, and also a benchmark
for zeroOrOneCharacterStringMatcher.Matches()
Signed-off-by: Oleg Zaytsev <mail@olegzaytsev.com>
When the label name of a matcher contains non-standard characters, like
a dot, or starts with a digit, it should be quoted.
If it's not quoted, then `VectorSelector.String()` isn't a valid PromQL.

When `zeroOrOneCharacterStringMatcher` wach checking the input string,
it assumed that if there are more than one bytes, then there are more
than one runes, but that's not necessarily true.
