[PATCH 0 of 2] unbuffered proxying CPU hog (ticket #2418)

[Maxim Dounin]

Hello!

The following patch fixes CPU hog observed with unbuffered SSL proxying 
after SSL errors (ticket #2418).  Fix is to always clear c->read->ready
flag when returning errors from ngx_ssl_recv().

An additional patch cleans up some win32-specific edge cases (not expected
to appear in practice though) when c->read->ready is not cleared when
errors or EOFs are returned from ngx_wsarecv() and ngx_wsarecv_chain().
