middle of a PDF. So here's a modification to sshzlib.c which enables
it to be compiled into a standalone Zlib decoder if you define
ZLIB_STANDALONE. As an added bonus, it (both standalone and in
PuTTY) also validates the Zlib header, just to make sure someone
hasn't defined a new compression format.

a result, ssh.c now needs to be prepared for zlib_decompress_block
to return failure.

malloc functions, which automatically cast to the same type they're
allocating the size of. Should prevent any future errors involving
mallocing the size of the wrong structure type, and will also make
life easier if we ever need to turn the PuTTY core code from real C
into C++-friendly C. I haven't touched the Mac frontend in this
checkin because I couldn't compile or test it.

absent, and also (I think) all the frontend request functions (such
as request_resize) take a context pointer, so that multiple windows
can be handled sensibly. I wouldn't swear to this, but I _think_
that only leaves the Unicode stuff as the last stubborn holdout.

uncompressed block at the end of each compressed packet) which we
were embarrassingly unable to deal with because we assumed every
uncompressed block contained at least one byte. Particularly silly
because I _knew_ about the existence of sync flush when I coded this
module. Arrgh. Still, now fixed.

compression. This involves introducing an option to disable Zlib
compression (that is, continue to work within the Zlib format but
output an uncompressed block) for the duration of a single packet.

smalloc() macros and thence to the safemalloc() functions in misc.c.
This should allow me to plug in a debugging allocator and track
memory leaks and segfaults and things.
