6a07a3f986 Fixes several issues with syntax/parse, and adds some tests. 
* byte-regexp? values should not be considered 3D syntax.
* hash? values are now allowed in serialized syntax properties with (template … #:properties (…))
* marshalling properties which were prefab structs called map on the result of struct->vector, changed it to struct->list as the struct "name" is always serializable.

a9ae341105 in-bytes: use unsafe-bytes-ref 
In the same way that `in-vector` uses `unsafe-vector-ref`,
make `in-bytes` expand to a use of `unsafe-bytes-ref`.

736cdfb2c1 yet more repairs to the interaction of errors and let-values 
Continuing the saga that includes 8190a7730d and d1ba9fbb6e, it turns
out that a 0-binding clause as the last one isn't so special after
all. A little later in the optimizer, now that we're sometimes moving
an error to the body, we can't assume that the body can be discard
if an error was detected.

3f2de918d8 fix variable-reference->namespace for phase > 0 
Set up bindings and shift phases as needed to make
`variable-reference->namespace` work in a run-time position when the
enclosing module is instantiated at a phase other than 0.

Thanks to Rohin Shah for the bug report.

b138c340e1 fix extended {read,peek}-char-or-special 
The changes in 08ca76b741 require the primitives to be reclassified
from non-CM to general.

Also, add an internal shortcut for checking arity.

08ca76b741 extend {read,peek}-char-or-special 
Support an external implementation of `read-syntax` by exposing
functionality that is currently internal to `read-syntax`: a srcloc
argument to a "special"-producing port function and wrapping special
results to reliably distinguish them from characters.

a860791d6f Windows: avoid using pipe code for file redirection 
When Racket is run with stdout or stderr redirected to a file,
then it must be treated as a regular file, otherwise flushing
and position counting doesn't work right.

04ec4d604e "under <platform>" -> "on <platform>"; "X" -> "Unix" 
I originally picked "under" as the preposition to go before
 a platform name, but obviously you should build "on" a
 platform, and "under" suddenly annoys me. The choice of "on"
 is now codified in the documentation style guide. Meanwhile,
 "Unix" insted of "X" seems more clear and consistent in the
 `racket/gui' docs.

 More usefully, this patch also fixes a few out-of-date
 platform-specific claims.
