c862ce4a75 feat(runtime, library/init/data/string/basic): add utf8_pos 
`utf8_pos` is a low level alternative for `string.iterator`.
TODO: implement `string.iterator` using it.

0556412f8d refactor(*): add runtime folder 
@kha The runtime folder includes what is needed to link a
standalone Lean program. It is still contains some unnecessary files.
We will be able to remove them after we release Lean4.

d2497d554f feat(frontends/lean): add support for unicode char literals and escape sequences 
TODO: we are not checking if the unicode escape values provide by the
user correspond to valud unicode scalar values. We should check how
other languanges handle this case.

b1e417805e fix(frontends/lean/scanner): do not treat 0xFF as end-of-file 
Fixes #1624.  We just replace 0xFF by 0x00 when reading a new input
byte.  This shows up as an unexpected token error.

a0a8103804 chore(frontends/lean): go back to 'c' as notation for characters 
This suggestion has been discussed at Slack.
We have decided to use #"c" as notation because we wanted to allow `'`
in the beginning of identifiers like in SML and F*. In particular,
we wanted to allow users to use 'a 'b 'c for naming type parameters
like in SML. However, nobody used this notation. In the Lean standard
library, we are using greek letters for naming type parameters.
So, there is no real motivation for the ugly #"c" syntax.

dfd2a23cd4 feat(frontends/lean): use #"c" instead of 'c' for character literals 
The new notation is the same one used in Standard ML.
It will also allow us to use ' in the beginning of identifiers like Standard ML.

8ceada5555 feat(frontends/lean): support binary, octal and hex literals 
Scanner will interpret numeric literals prefixed with '0b', '0o', and
'0x' as binary, octal, and hex decimal values respectively.  The prefix
character ('b', 'o', 'x') may be upper or lower case.
