8d0bee8629 PuTTYgen initial version. Still to do are basic user-friendliness 
features (prompt for passphrase twice, prompt before overwriting a
file, check the key file was actually saved OK), testing of the
generated keys to make sure I got the file format right, and support
for a variable key size. I think what's already here is basically
sound though.

3e83d75154 Add a config option to emulate the HMAC bug in commercial SSH v2.3.x 
and earlier (namely, it uses only 16 bytes of key rather than 20).

fd5588d087 Robert de Bath's big patch: 
- cope with strange WinSock wrappers not supporting SIOCATMARK
  - define yet more terminal compatibility modes
  - support UK-ASCII (just like US-ASCII but # is a sterling sign)
  - support connection keepalives at a configurable interval

be exported willy-nilly. It encourages people to use them.

9922072a8d Peter Schellenbach's patch: re-implement the PuTTY cryptographic 
functions as calls to the MS Crypto API. Not integrated into the
Makefile yet, but should eventually allow building of an SSH-enabled
PuTTY which contains no native crypto code, so it can be used
everywhere (and anyone who can get the MS encryption pack can still
use the SSH parts).

96dbf9c6e6 First stab at the ability to compile puttytel.exe, an SSH-free 
variant which is patent-safe in the US and legal in France and
Russia. This is a horrible hack in some ways: it's shown up serious
deficiencies in the module boundaries. Needs further work, probably
once the SSH implementations are recombined.

a8d5838ebc Robert de Bath's multi-purpose patch, slightly modified. 
- ^E answerback is now `PuTTY'.
 - The framework is now in place for the scrollback to reset to
   bottom on display _or_ keyboard events _or_ both. An actual
   configurable option isn't yet present, but most of the code is in
   place.
 - Try to deal with the problems where incoming data gets dropped
   after decoding but before display.
 - Scrollback behaviour has changed: instead of keying it off
   `scroll' versus `delete top line', things now go into the
   scrollback from _either_ of those but only if the primary screen
   is selected. Should fix problems with `less' and talkers.
 - must_update variable has gone because rdb correctly observed that
   it didn't seem to be doing a great deal :-)
