Improve escape sequence support
Specifically:
1. In the double-quoted strings we now only do effective escaping of the
special `$("\` characters plus `)` for symmetry.
2. There is now support for "escape sequence expansion" in the form $\X where
\X can be any of the C/C++ simple escape sequences (\n, \t, etc) plus \0
(which in C/C++ is an octal escape sequence). For example:
info "foo$\n$\tbar$\n$\tbaz"
Will print:
buildfile:1:1: info: foo
bar
baz
