43d6684ab9 avoid stack-overflow in scheduler-triggered foreign calls 
While a foreigh call is normally guarded by a check on the amount
of available stack space, a callbacks triggered by the
scheduler will first put Racket in no-stack-overflow mode, and
then it's too late to check stack space before making further
foreign calls. With Cocoa, there's some chance that the process
will run out of space. Avoid the mismatch by checking the stack
availability at the start of a scheduler iteration.

7304420691 fix peek implementation in R6RS input ports 
The peek operation must not block, otherwise the port behaves
badly for `sync`.

Based on a bug report from Brett Stahlman.

c627b0fc6f pict: make hc-append, etc., match the docs 
Allow pict arguments, with or without a separation-size
argument.

The recently added contract has rules out providing a
separation size with no arguments, which had been allowed
before. The underlying problem, though, was an inconsistency
in the implementation that allowed 0 pict arguments only
in the case that a separation size is provided.

dcfe7ede67 make some arity error messages for ->i contracted functions 
slightly less terrible

... but ->i still doesn't do as good a job as -> and ->* do for arity
errors (specifically, ->i is still letting the blame-less errors that
application constructs thru when it could be assigning blame)

1542398822 optimizer: move more things inside let and begin 
Refactor the code to move inside 'let' or 'begin'.

Also, in the test position of a 'if', recognize the 'not' inside a 'let' or 'begin'.
For example, transform (if (begin ... (not p)) x y) => (if (begin ... p) y x)
Previously, this conversion was made only when
the 'not' was the outermost expression.

And use the refactored code to move application inside 'let' or 'begin' in a single step
For example, transform ((let (...) ... (let (...) ... f) x) => (let (...) ... (let (...) ... (f x))
In the conversion, it's necessary to shift x to the new coordinates inside the 'let's.
In the new version x is shifted only once.
