fb80d18428 syntax/parse: Arrange for built-in macro’s names to be preserved 
The dance that syntax/parse performs to lazily load its implementation
rewrites uses of syntax/parse macros in such a way that their original
names were discarded, which shows up in error messages. By simply
invoking the underlying transformer directly in the proxy macro instead
of expanding to a rewritten use, users’ names can be preserved.

fixes #1909

93ae78af91 rktio: better ltps checking for epoll support 
Don't report ltps success for file descriptors that are not supported
by epoll.

Racket ports probably were not affected, since Racket doesn't try ltps
registration for regular files or devices like /dev/null that report
always being ready.

c3f61a7626 add ffi/unsafe/port 
Provide unsafe functions for working with file descriptors and
sockets. Although more functions are potentially useful, these
reflect the one scurrently exported by the C API.

544b7a3d53 fix continuation-barrier checking 
Continuation-barrier checking was sometimes too strict,
disallowing jumps out past a barrier (as opposed to
into a barrier) that should be allowed.

7aff978a1f fix merging of marks when applying a composable continuation 
When a composable continuation has continuation marks that should
be merged with marks in the immediate continuation frame when
the continuation is applied, then mergeing did not always work.
It only worked in the case that the merge cadidates are the only
marks, because the merging check used the wrong end of the captured
sequence of marks.

f816a8afcd syntax/parse: add ~undo, #:undo for unwinding effects 
Note: this version doesn't work with ~commit or ~!, because
it stores both choice points and undo actions in the failure
continuation. Commit and cut should discard choice points but
preserve undo actions.

6a9a269546 bytes-utf-8-{length,index}: fix bytecode optimizer bug 
The `bytes-utf-8-{length,index}` function was incorrectly marked as
always returning a fixnum.

1e1426a570 Revert "doc correction for will-execute" 
This reverts commit 52e7267273.

The change was for `will-try-execute`. And while the change
is a good idea, `will-try-execute` doesn't acually accept
the extra argument.

512910c83f expander: fix 'module-begin expansion with definition contexts 
Using `(local-expand <expr> 'module-begin <stops> def-ctx)` didn't
work right, because definitions added to `def-ctx` were not visible.
(While adding definitions before `module-begin` expansion is an unusual
thing to do, there's no reason that it has to fail.)
