1. By default, soft disable AES-CBC. It isn't offered as a default
encrypt algorithm, but may be set at runtime.
2. Add guard where AES-CBC can be added back as a default.
3. Add option to example client to run it with a custom encrypt
algorithm list.
4. In the client, add macro to add items to the arg lists while checking
the number of items in the list.
This implements Keyboard-Interactive authentication.
Adds an additional callback set by `wolfSSH_KeyboarAuthPrompts()` which
will set a callback in the server to ask the application to provide the
prompt details for the client.
1. In the echoserver, change the names of the defines for the
static memory values.
2. Modify the client common functions for keys and certs to take a heap
value for their allocations.
3. Update the client's use of the common key and cert function calls to
pass NULL for the heap.
4. Add a static memory description for the sftp client code.
1. Change GetTerminalSize() to GetTerminalInfo().
2. Add the term variable to the things GetTerminalInfo() looks up.
3. Return the actual value of the environment variable TERM to the
server. If one isn't present, default to "xterm".
4. Clean up the whitespace in SendChannelTerminalRequest().
Misc other changes:
1. Cleanup whitespace in the recently added function
SendChannelOpenFail().
2. Add labels to the parameters in the prototype for
SendChannelOpenFail().
3. Remove the CR addition for Windows in the example client. Causes the
enter key to double-strike.
1. Add quit parameter to the example client's thread_args structure.
This will be used to let the windowMonitor thread know the
application is quitting.
2. If the windowMonitor's quit flag is set, it will exit and not call
wait again.
3. Join the windowMonitor thread rather than cancel it.
When the example client is using non-blocking sockets, sometimes they
don't block. The monitor thread on the socket wasn't handling
WS_WANT_READ explicitly, and treated it as a fatal error. It should be
reset to WS_SUCCESS.
