Add Unicode strings and symbols
This adds full Unicode strings as a datatype, and it adds some
minimal functionality. The terminal and port encoding is assumed
to be ISO-8859-1. Non-ISO-8859-1 characters are written or
input as string character escapes.
The string character escapes now have 3 forms: \xXX \uXXXX and
\UXXXXXX, for unprintable characters that have 2, 4 or 6 hex digits.
The process for writing to strings has been modified. There is now a
function scm_i_string_start_writing that does the copy-on-write
conversion if necessary.
To compile strings that may be wide, the VM storage of strings and
string-likes has changed.
Most string-using functions have not yet been updated and may break
when used with wide strings.

bytevectors have "element type" field, e.g. for generalized-vector-ref
Bytevectors have a very close relationship to other forms of uniform
vectors. Often you want to view a u64vector as a series of bytes, for
writing over a socket; or to process an incoming stream using the
convenient and less error-prone s16vector-ref API rather than
bytevector-s16-native-ref.
The essential needs of the representation of a bytevector and an
s64vector are the same, so we take advantage of that and extend the
bytevector implementation to have a "native type" field, which defaults
to VU8.

however.

to check for another class of bugs: overflow. The length stored on the
