Subject: [PATCH] session: support server banners up to 8192 bytes (was: 256)
 
 If server had banner exceeding 256 bytes there wasn't enough room in
 `_LIBSSH2_SESSION.banner_TxRx_banner`. Only the first 256 bytes would be
 read making the first packet read fail but also dooming key exchange as
 `session->remote.banner` didn't include everything.
 
 This change bumps the banner buffer to 8KB to match OpenSSH.
 
 Fixes #1442
 Closes #1443
