fe945fe1dc Mark cs tests as allowing failure for Gitlab 
This is a temporary measure in order to avoid Gitlab marking commits as failing. This is a known issue.

38f518a7aa Define MZ_DECLARE_NORETURN to use noreturn attribute 
This helps the static analyzer understand which functions don't
return, and therefore improves the static analysis results greatly.

7a6536ab6d Remove unnecessary exit(0); 
This was necessary to avoid warnings in a specific compiler but after
adding MZ_DECLARE_NORETURN, this is now unnecessary.

5b837b895f Put all declarations with NORETURN in a single line 
If declarations are not in a single line makex.rkt gets confused and
mis-parses the declarations.

0659e51b3f Mark other error functions as NORETURN 
Related to PR #2472, marks a few other functions as NORETURN.
Namely:
	- scheme_signal_error
	- scheme_wrong_count
	- scheme_wrong_count_m
	- scheme_case_lambda_wrong_count
	- scheme_wrong_type
	- scheme_wrong_contract
	- scheme_wrong_field_type
	- scheme_wrong_field_contract
	- scheme_arg_mismatch
	- scheme_contract_error
	- scheme_wrong_return_arity
	- scheme_unbound_global

Unfortunately static analysis is done per compilation unit, so
although, for example, scheme_wrong_contract calls scheme_raise_exn
and the latter is already marked NORETURN, the analyzer does not know
this. Therefore we need to manually propagate the NORETURN for each
function declaration.

b7654d9a84 cs: avoid uninitialized bytevectors via ffi/unsafe 
Zeroing out allocated memory is required by the specification of
`alloc` from `ffi/unsafe`.

858a925c16 remove another dead assignment to buf, which also causes leak 
These leaks happen just once in startup code, so they
didn't matter in practice --- but, obviously, its better to
fix them.

add unsafe-poll-fd, unsafe-fd->evt (#2414) 
The unsafe-fd->evt interface is based on unsafe-{file-descriptor,socket}->semaphore. 
The main differences are that these events are level-triggered, not edge-triggered, and 
they do not cooperate with ports created by unsafe-{file-descriptor,socket}->port.

3e301d22b5 Mark scheme_raise_exn as noreturn - regenerate schemex 
scheme_raise_exn raises an exception and doesn't return.
Static analysis tools find a huge amount of problems with regards
to memory leaks that are actually false positives because the tools
are not aware the function does not return. Marking it as such aids
further inspection of real problems.

30e260835f fix \D, \S, \W in string regexp 
The documentation and implementation were confused about whether \D,
\S, and \W match non-ASCII characters. Now they do. The new regexp
implementation (as used in Racket CS) already matched them.

1722e49c85 Remove dead code 
I understand what the idea is in this file, except this code won't
work like the author expected it to. Variables marked for wiping won't
be wiped unless they are marked as volatile. The compiler will simply
remove the code wiping the variables and issue a warning, which is
what brought me to look into this code in the first place.
