Julius Volz 46c5260761 Support escape sequences in strings and add raw strings.
This adapts some functionality from the Go standard library for string
literal lexing and unquoting/unescaping.

The following string types are now supported:

Double- or single-quoted strings:

  These support all escape sequences that Go supports in double-quoted
  string literals. The difference is that Prometheus also has
  single-quoted strings (instead of single-quoted runes in Go). Raw
  newlines are not allowed.

Backtick-quoted raw strings:

  Strings quoted in backticks are treated as raw strings just like in Go
  and may contain raw newlines and other special characters directly.
