compiler/zo-marshal: allow extflonum literals
move find-string tests into the wxme test suite
generalize the support for mouseover tooltips so that
the computation of the string doesn't have to happen
during macro expansion, but can happen only when check syntax
is in the picture
libffi: fix problems with gcc-4.0 on 32-bit Mac OS X

Based in part on https://trac.macports.org/changeset/122079
another attempt to eliminate references to the original
installation directory from the drracket tool docs

please include in 6.1.1
Avoid requires of contracts when they're not used.

This changes when various libraries that provide contract
support to possible contracted bindings to declare when
those bindings are needed.

Probably, each static-contract combinator should manually
add to the list, instead of having one fixed static list,
but this is a start.

Saves about 10ms in startup for an empty TR module on my
laptop.

Thanks to Robby for the idea.
Add implies from typed-racket-lib to unstable-contract-lib.

Typed Racket, as of 8ea8c54eb, can add explicit require lines
to the expanded module, which can confuse the dependency
analyzer. An explicit implies declaration avoids the problem,
although I'm not sure that this is the right solution.
Send thunks to check-syntax for type tooltips

This avoids the cost of computing the printed types
to some degree. It still does have overhead (~5%) over
not computing anything related to tooltips because of
the cost of traversing the type table and computing
tooltip locations.
add the get-autowrap-bitmap-width method to text%
adjust the wrap-bitmap-width field to always have an inexact number
try to take the autowrap bitmap into account when sizing the repl input box
document setup/main-doc
make path->relative-string/library use "<doc>/...." prefixes files in the docs
simplify the drracket/check-syntax documentation a little
XFORM_END_SKIP -> XFORM_SKIP_PROC in example.

The XFORM_SKIP_PROC example incorrectly used XFORM_END_SKIP,
it should have used XFORM_SKIP_PROC instead.
Fix/add base-env types for Ref 14.4.3
db: add empty string test for "text" type
simplify paths before using as hash keys
small tweaks to raco show-dependencies

- print '#%kernel instead of (quote #%kernel)
- add -l for more human-friendly output that shows direct requires
change set/c default #:kind to dont-care, to match docs

- add set/c tests
