With this flag the primitive is not tested in primvars.ms but other
parts of the compiler can use the signature/flags.
Also, add a signature to every system boolean primitive.

Probably makes no difference right now, since these internal functons
rarely show up in the process of optimizing user programs, but just in
case.

Can't simply use a continuation reified by an attachment
operation, because it is probably a 1-shot continuation
that needs to be promoted.
original commit: 8201aff06df8011ffbc41f217d50e4c430d75bb5
Effectively, change a `call/cc` call to `let/cc` when it appears in
the tail position of a function. This change takes advantage of
continuation-reification support that was built for continuation
attachments.

The MRG32k3a generator is fast when using unboxed floating-point
arithemtic. Since the Scheme compiler doesn't yet support that,
build MRG32k3a into the kernel and provide access via
`pseudo-random-generator` functions.

If normal 1-shot continuations are mixed with opportunistic 1-shot
continuations created by `call-setting-continuation-attachment`, then
promoting an opportunistic 1-shot at a GC is wrong unless the whole
chain is promoted.

Include an extra part in the Chez Scheme version number, which both
helps indicates the Racket fork and versions it.

Also, rename `call-with-current-continuation-attachment` to
`call-getting-continuation-attachment`.
original commit: e2a00e6d641b92918c4911c27ba14949748fd291
Add a shortcut check when refiying the continuation frame in tail
position, which is significantly cheaper when the frame is already
there. We pay down the check by skipping an attachment-lists check
that is not needed if the frame is newly reified.
Aslo, add a one-shot continuation-frame cache, which makes a shallow
temporary attachment cheaper, as in
(let loop ([i N])
(if (zero? i)
0
(loop (call-setting-continuation-attachment
i
(lambda ()
(f (sub1 i)))))))
The cache is just one frame. Keeping a chain of allocated-by-not-GCed
frames doesn't pay off.
Meanwhile, remove the leftover `$shift-attachment` library entry.

... and eq-hashtable-cell and symbol-hashtable-ref-cell,
which are just like hashtable-cell, except that if the given
key isn't present, they return #f instead of mutating the table.

Previously it was using #!/bin/bash as its interpreter. It is not
compatible with FreeBSD because bash is not installed by default.
The update-revision script is #!/bin/sh compatible and there are
other examples of #!/bin/sh scripts in the codebase so the change
is consistent with them.

Avoid tripping into +nan.0 by using 0 instead of 0.0
for the imaginary part of a real number and by using
`atan` with two arguments instead of one.

Correct the case that converting the second argument to an inexact
numbe produces an integer by losing precision.

The `(cdr tc-ptr-offsets)` in the recrusrion was wrong, but use
`thread->objects` and `thread->stack-objects` to work more generally.

Use OSSP UUID on {Free,Open}BSD and native UUID on NetBSD.
Building on OpenBSD requires a filesystem mounted with wxneeded.

@gus-massa's adjustments to the Racket test suite exposed more places
where the "primdata.ss" spec was wrong.
original commit: 5cb4996c7b317307299e8dd55a25e8e58144a30e
It fails when the argument is +inf.0, so it's not possible to make it unsafe
automatically when the argument is a number.
