1. Removed some unused macros in the configure.ac script.
2. Added option for enabling TCP/IP Forwarding.
3. Coalesced the option enable checks to one location in the configure script.
4. Removed redundant compile flags from the wolfSSH automake include.
5. Added a check of the BUILD_SCP option to leave out the wolfcsp file as needed.
6. Removed the redundant debug flags from the ax_harden macro since we add them at the configure level.
7. Modified the ax_harden macro to add the flags to AM_CFLAGS rather than CFLAGS.
8. Removed redundant AM_CFLAGS from the include.am that are adding them to their build's CFLAGS.
9. Replaced the have-wolfssl macro with AC_CHECK_LIB.
10. When adding per-target CPPFLAGS, add the AM_CPPFLAGS back in.
11. remove redundant call to wolfSSH_Init() from echoserver
12. Add runtime configuration of the session window size and max packet size.
13. Parse the TCP/IP direct connect flavor of the Channel Open message.
14. Save and release the host and origin addresses.
15. Added an example forwarding tool.
16. Move and rename the FIND_SELF and FIND_PEER constants.
17. Add planned functions ChannelSend, ChannelRead, ChannelExit, worker.
18. Add new function ChannelNext, which returns the next channel in the list.
19. Changed SendBuffered() from static to local so it could be used by the worker.
20. Separated creating a channel and sending an channel open request.
21. Added status code for pending open channel and for received data.
In ax_harden_compiler_flags.m4, a couple of the AC_REQUIRE macros were being used to check for the presence of another macro. Replaced them with uses of AX_REQUIRE_DEFINED which checks for the presence of a macro. AC_REQUIRE ensures a macro is expanded.
1. Update several of the macro files paralleling wolfSSL's m4 files.
2. Check the ar options and if available add the "U" options.
3. Add the -Xcompiler flag ahead of -Qunused-arguments for -pthreads.
