In converting a new style BIO_read() call into an old one, read
as much data as we can (INT_MAX), if the size of the buffer is
>INT_MAX.

A BIO_read() 0 return indicates that a failure occurred that may be
retryable. An SSL_read() 0 return indicates a non-retryable failure. Check
that if BIO_read() returns 0, SSL_read() returns <0. Same for SSL_write().

The asyncio test filter BIO already returns 0 on a retryable failure so we
build on that.

A zero return from BIO_read()/BIO_write() could mean that an IO operation
is retryable. A zero return from SSL_read()/SSL_write() means that the
connection has been closed down (either cleanly or not). Therefore we
should not propagate a zero return value from BIO_read()/BIO_write() back
up the stack to SSL_read()/SSL_write(). This could result in a retryable
failure being treated as fatal.

The current version of the VMS compiler provides C99 features,
strictly language wise.  Unfortunately, even the most recent standard
library isn't fully updated for that standard, so we need to use an
earlier standard that the compiler supports.

Most importantly, this affects the __STDC_VERSION__ value, which the
compiler unfortunately currently defaults to 199901L.  With this
change we won't have to give VMS special treatment when looking for
features based on that macro.
