Add missing initialization of 'type_c' field of a SSH signature in
'pki_do_sign_sessionid' procedure.
If libssh is compiled with GCrypt, 'dh_handshake_server' fails with
"Could not sign the session id" error. The change fixes that.

Enable retrieving the "ecdsa-sha2-nistpNNN" name of ECDSA keys with a
new 'ssh_pki_key_ecdsa_name' API. This gives more information than the
'ssh_key_type_to_char' API, which yields "ssh-ecdsa" for ECDSA keys.
The motivation is that this info is useful to have in a server context.
The torture_pki unit test is updated to include the new API, and a few
more passes are added to additionally test 384 and 521-bit keys.

In packet_send2, rather than issue two separate buffer_prepend_data calls
(each of which may entail realloc + memmove + memcpy), elide the prepend
work into a single buffer_prepend_data: the header information is computed
locally, and a single 5 byte prepend operation is now done instead of
prepending 1, then 4 bytes.

state is set to SSH_SESSION_STATE_SOCKET_CONNECTED. Result of this fix can be
verified by running torture_connect test (torture_connect_socket) with -vvvv

The libssh library by default does not allow in-source build (with cmake
MacroEnsureOutOfSourceBuild macro). The INSTALL file (implicitly) suggests
creating a build directory. So lets add build to list of git ignore files to
avoid complaints from git.

When accepting a new connection, a forking server based on libssh forks
and the child process handles the request. The RAND_bytes() function of
openssl doesn't reset its state after the fork, but simply adds the
current process id (getpid) to the PRNG state, which is not guaranteed
to be unique.
This can cause several children to end up with same PRNG state which is
a security issue.
