I've finally got tired of all the code throughout PuTTY that repeats the same logic about how to format the SSH binary primitives like uint32, string, mpint. We've got reasonably organised code in ssh.c that appends things like that to 'struct Packet'; something similar in sftp.c which repeats a lot of the work; utility functions in various places to format an mpint to feed to one or another hash function; and no end of totally ad-hoc stuff in functions like public key blob formatters which actually have to _count up_ the size of data painstakingly, then malloc exactly that much and mess about with PUT_32BIT. It's time to bring all of that into one place, and stop repeating myself in error-prone ways everywhere. The new marshal.h defines a system in which I centralise all the actual marshalling functions, and then layer a touch of C macro trickery on top to allow me to (look as if I) pass a wide range of different types to those functions, as long as the target type has been set up in the right way to have a write() function. This commit adds the new header and source file, and sets up some general centralised types (strbuf and the various hash-function contexts like SHA_State), but doesn't use the new calls for anything yet. (I've also renamed some internal functions in import.c which were using the same names that I've just defined macros over. That won't last long - those functions are going to go away soon, so the changed names are strictly temporary.)
