bn_restore_invariant (and the many loops that duplicate it) leaves a
single zero word in a bignum representing 0, whereas the constant
'Zero' does not have any data words at all. Cope with this in
bignum_cmp.
(It would be a better plan to decide on one representation and stick
with it, but this is the less disruptive fix for the moment.)

now check that all the modular functions (modpow, modinv, modmul,
bigdivmod) have nonzero moduli, and that modinv also has a nonzero
thing to try to invert.

PuTTY does not trim a colon suffix off the hostname if it contains
_more than one_ colon. This allows IPv6 literals to be entered.
(Really we need to do a much bigger revamp of all uses of hostnames to
arrange that square-bracketed IPv6 literals work consistently, but
this at least removes a regression over 0.62.)

not so silly in the 1990s and before I implemented scrollback
compression, but it's been a ridiculously low default for a while now.

within the same string that destfname points to the start of, so
freeing it causes at best a double-free of destfname and more likely a
free of something that isn't even the start of an allocated block.

palette_set() to be bogus. Fortunately, this isn't exploitable through
the terminal emulator, because the palette escape sequence parser
contains its own bounds check before even calling palette_set().
While I'm at it, fix the same goof in the OS X version! That port is
more or less abandoned, but that's no excuse for leaving obviously
wrong code lying around.

support: transform_jumplist_registry should give its caller
dynamically allocated data if and only if it returns JUMPLISTREG_OK,
and get_jumplist_registry_entries should test the return value against
JUMPLISTREG_OK rather than a value from a totally different enum.

The most interesting one is printer_add_enum, which I've modified to
take a char ** rather than a char * so that it can both realloc its
input buffer _and_ return NULL to indicate error.

(This has also required me to add a currently unused nonfatal() to
PuTTYgen, since although PuTTYgen won't actually try to delete
putty.rnd, it does link in winstore.c as a whole.)

strerror as I can arrange, wrapping up all the ugly FormatMessage
nonsense and caching previously looked-up messages for reuse so that
callers can treat them as static.

sitting on a pile of buffered data waiting for WINDOW_ADJUSTs, we
should throw away that buffered data, because the CHANNEL_CLOSE tells
us that we won't be receiving those WINDOW_ADJUSTs, and if we hang on
to the data and keep trying then it'll prevent ssh_channel_try_eof
from sending the CHANNEL_EOF which is a prerequisite of sending our
own CHANNEL_CLOSE.

parallels a similar mechanism in winnet.c and came over by copy and
paste, but is pointless in the Unix networking API.
On Windows, if you're using a mechanism such as WSAAsyncSelect which
delivers readability notifications as messages rather than return
values from a system call, you only get notified that a socket is
readable once - it remembers that it's told you, and doesn't tell you
again until after you've done a read. So in the case where we
intentionally stop reading from a socket because our local buffer is
full, and later want to start reading again, we do a read from the
socket with MSG_PEEK set, and that clears Windows's flag and tells it
to start sending us readability notifications again.
On Unix, select() and friends didn't do anything so strange in the
first place, so the whole mechanism is unnecessary.

ssh.com and OpenSSH key import loops, we should also null it out so
that the cleanup path doesn't try to re-free the same pointer.
