47fcdd4916 Sped up floor-log/base and ceiling-log/base, and made them correct on flonum inputs. 
This change significantly increases the speed of number formatting, making extreme-bounds-tests.rkt run in about 1/4 the time.

Should consider moving these into racket/math, since floor-log/base generalizes order-of-magnitude.

e8902f9981 added a hack to keep DrRacket from freezing when it is unable to 
detect if a (n online check syntax) rename would conflict with
an existing name. (This can happen because the remote place's
custodian gets shutdown due to, for example, another tab's online
check syntax running.)

a0ef78e97b adjust online check syntax to try to fix a bug where renaming information 
can get "stale" and cause DrRacket to deadlock (this commit just sets
up some stuff to make one fix possible, but that fix doesn't seem to
be working, so the actual fix is disabled (see comment in commit))

ef846caaa1 tighten bound for Mac OS X 10.6 localtime() hack 
It looks like my bound for last time was too conservative,
in that I looked for the lowest number that didn't seem
to fail in 10.6. The range of failing values is apparently
not continuous.

I've tightened the bound to match the lowest
number that produces a useful result on my 10.7 machine,
assuming that it works for a continuous range there.
(The new bound is higher than the number previously used as
a lower bound.)

Merge to 5.2.1

(Related to the server auto-publishing new tags and branches, configured
to do that in "~ftp/pub/racket/libs/{heads,tags}" respectively.)

6b6beb601e add PLT_VALIDATE_COMPILE to enable extra checking of the compiler 
Setting the environment variable causes the bytecode compiler to run
the bytecode validator (which is normally applied to input from a
bytecode file) immediately on all of the compiler's own results.

706d5026ac fix bytecode compiler bug 
Certain `lambda'-lifting operations can cause information
about the flonumness of a variable to get lost, leading
to a mismatch between the closure's flags and flags on
a variable reference. (The bytecode validator could detect the
bug when loading the broken bytecode. The broken information,
meanwhile, was only used by the JIT.)
