Parents and children of check-in [a27c6affe5]

* tests/tlsIO.test: enabled tests 2.10, 7.[1245] (there is no 3), which now pass. Added some comments to other failing tests. check-in: 7b1825af0d user: hobbs tags: tls-1-3-io-rewrite
* tlsIO.c: changed all the channel procs to start with Tls* for better parity when comparing with Transform channel procs. Rewrote TlsWatchProc, added TlsNotifyProc according to the new channel design, which also leaves TlsChannelHandler unused. * tlsBIO.c (BioCtrl): changed BIO_CTRL_FLUSH case to use Tcl_WriteRaw instead of Tcl_Flush (to operate on correct channel in the stack instead of starting at the top again). Would otherwise cause a recursive stack bomb when implicit handshaking took effect. check-in: a27c6affe5 user: hobbs tags: tls-1-3-io-rewrite
* tests/tlsIO.test: removed changes made to test suite (all tests that ran before now pass correctly), and changed some accept proc args to reflect that a sock is an arg, not a file. check-in: 107ae51e18 user: hobbs tags: tls-1-3-io-rewrite
