ssh_match_group() has been moved from misc.c to match.c, because it fits
better with other match_*() functions in match.c
The name of the function has also been changed from "ssh_match_group" to
"match_group" to be consistent with the naming of the other match.c
functions.

Previously the call to ssh_handle_packets() would be skipped if the buffer
wasn't empty. This meant that if ssh_channel_poll() was called on a non-blocking
channel with callbacks to handle incoming data, and the buffer already had some
data, the callbacks would never be called.

Text has been added to the documentation of ssh_options_set() and
ssh_bind_options_set() which explains what the third argument (value argument)
should be depending on the option value to set.

For the data type of the third argument <value> corresponding to the
second argument <option type>, the documentation of ssh_options_set()
and ssh_bind_options_set() uses a scheme of (data_type *) in some
places whereas (data_type) in other places. Here data_type is the type
of the value which is to be set (it can be const char *, int, bool,
long, ssh_key etc)
This commit removes this inconsistency and uses the (data_type)
scheme everywhere.

The argument for RSA_MIN_SIZE ssh and sshbind option is of
(int *) type, and hence the caller can supply a pointer to a
location storing a negative value. The commit adds a check to
not allow minimum rsa key size to be set to a negative value.

This should prevent the long standing random failures of libgcrypt pipeline. I
was recently able to reproduce it only with dropbear, which sounds like choking
on the signature starting with bit 1, possibly interpretting it as a negative

Legacy code in 'ssh_set_callbacks' will fallback to
'ssh_legacy_log_callback' (if the current log cb is
NULL) setting the user data to the current session.
However, if any other session is created afterwards,
it won't update the user data with the new session,
potentially leading to a use-after-free.
Fixes#238.
