Commit c306a693f3 ("buffer: Use size_t for argc argument in
ssh_buffer_(un)pack()") mentioned unpack in the commit log, but it only
touches the pack variants. Extend the conversion to unpack.
Pre-initialize the p pointer to avoid possible use before
initialization in case of early argc check failure.
This fixes build failure:

Add a small helper for ssh_buffer to ensure that the buffer has a
certain amount of space already preallocated. This can be useful in case
it is known how much data is going to be added to a buffer, to avoid
multiple reallocations.
Make use of it in few places in the library.

Note that removing ssh_buffer_get_begin() doesn't break API
compatibility, as this functions has never been exposed (it only
has the LIBSSH_API prefix).

That function permits chaining of buffer values to minimize buffer handling
in packet sending code.
