Big round of changes to UCD tables, no longer need runtime conversion.

Previous tables had to be compiled using 9.2, and couldn't use bytevector,
unicode string syntax, or R7RS char/string escapes.  Now they do that which
results in some small space savings and less work at cold load.

Additionally I changed the representation of multiple-code-point values from
strings to vectors.  The old representation depended on the fact that
vector->string didn't do normalization, so those strings can't be constructed at
compile time (they'll be normalized) and anyway it's not good to depend on that
feature of vector->string.

Define (flo:ulp x) to be distance to next float in direction of x.

Thus, (flo:ulp 1.) = (flo:ulp -1.) = flo:ulp-of-one.  Bottoms out at
infinity: (flo:ulp x) = x if x is infinite.  This definition applies
to zero, too, giving the smallest subnormal.

Eliminate flo:epsilon.

The name is confusing.  It means two different things: the distance
from 1 to the next positive floating-point number, and the maximum
relative error of rounding to the nearest floating-point number.
Provide the separate names flo:ulp-of-one and flo:error-bound for
these so that you're not even tempted to be confused by the name
`epsilon'.

(But continue to say `eps' in the proofs in the comments where it's
obvious that we're talking about relative error bounds and a short
name for that is essential for legibility.)
