Always update prt->data with atomic xchg-op.
Check for NULL data to detect racing port terminator.
Use NULL, as THE_NON_VALUE can be a valid pointer on debug VM.

hsize field was not set leading to VM crash

The warning is:
sys/common/erl_poll.c:2513:72: warning: for loop has empty body [-Wempty-body]
for (prev_ps = pollsets; ps != prev_ps->next; prev_ps = prev_ps->next);

The test needs to be false to fail, not true. This was noticed with the
following warning, where marking erl_assert_error as non-returning didn't
help:
beam/erl_gc.c:2772:2: warning: variable 'refc' is used uninitialized whenever switch default is taken [-Wsometimes-uninitialized]

When the offending code is reached, new_crr is either uninitalized or
have been set to NULL. This patch removes the following warning:

Found by valgrind. Probably safe on opt-VM due to CHICKEN_PAD.
|
|
|
|
Valgrind complained that erts_cmp_bits sometimes read one byte too much
from bitstrings. The byte was never used and the invalid read is safe
in opt-VM due to padding in binary allocation (CHICKED_PAD).

The bugfix is to only convert backslashes to forward slashes on
windows and not on any other platforms.
