call SSL_read/write, looping on SSL_ERROR_WANT_READ/WRITE. I'm sure
* camel-tcp-stream-openssl.c (my_SSL_read, my_SSL_write): call SSL_read/write, looping on SSL_ERROR_WANT_READ/WRITE. I'm sure there's a perfectly good reason that the API works this way. No, really. (stream_read, stream_write): use my_SSL_read and my_SSL_write. Fixes at least ximian 8593, and probably 6024 and maybe 10366, at least for OpenSSL. There may be a parallel NSS bug? svn path=/trunk/; revision=13121
