Thom Brown reported that SSL connections didn't seem to work on Windows in
9.5. Asif Naeem figured out that the cause was my_sock_read() looking at
"errno" when it needs to look at "SOCK_ERRNO". This mistake was introduced
in commit 680513ab79, which cloned the
backend's custom SSL BIO code into libpq, and didn't translate the errno
handling properly. Moreover, it introduced unnecessary errno save/restore
logic, which was particularly confusing because it was incomplete; and it
failed to check for all three of EINTR, EAGAIN, and EWOULDBLOCK in
my_sock_write. (That might not be necessary; but since we're copying
well-tested backend code that does do that, it seems prudent to copy it
faithfully.)
