This gets rid of yet another huge pile of beating around the bush with length-counting. Also, this time, the BinarySink in question is a little more interesting than just being a strbuf every time: on Windows, where the shared-memory Pageant IPC system imposes a hard limit on the size of message we can return, I've written a custom BinarySink implementation that collects up to that much data and then gives up and sets an overflow flag rather than continue to allocate memory. So the main Pageant code no longer has to worry about checking AGENT_MAX_MSGLEN all the time - and better still, the Unix version of Pageant is no longer _limited_ by AGENT_MAX_MSGLEN in its outgoing messages, i.e. it could store a really extra large number of keys if it needed to. That limitation is now a local feature of Windows Pageant rather than intrinsic to the whole code base. (AGENT_MAX_MSGLEN is still used to check incoming agent messages for sanity, however. Mostly that's because I feel I ought to check them against _some_ limit, and this one seems sensible enough. Incoming agent messages are more bounded anyway - they generally don't hold more than _one_ private key.)
PuTTY README
============
This is the README file for the PuTTY installer distribution. If
you're reading this, you've probably just run our installer and
installed PuTTY on your system.
What should I do next?
----------------------
If you want to use PuTTY to connect to other computers, or use PSFTP
to transfer files, you should just be able to run them from the
Start menu.
If you want to use the command-line-only file transfer utility PSCP,
you will probably want to put the PuTTY installation directory on
your PATH. On Windows 7 and similar versions, you can do this at
Control Panel > System and Security > System > Advanced system
settings > Environment Variables.
Some versions of Windows will refuse to run HTML Help files (.CHM)
if they are installed on a network drive. If you have installed
PuTTY on a network drive, you might want to check that the help file
works properly. If not, see http://support.microsoft.com/kb/896054
for information on how to solve this problem.
What do I do if it doesn't work?
