**MERGED FROM MAIN BRANCH, RE-PATCHED**
* command-ssh.c: New file.
* findkey.c (modify_description): New function.
(agent_key_from_file): New variables: comment, comment_sexp,
comment_length, desc_text_modified; extract comment from S-Exp,
pass modified version to unprotect().
* agent.h: Declare: start_command_handler_ssh.
(struct opt): New member: ssh_support.
* gpg-agent.c: Include <sys/select.h>.
New configuration option: ssh-support.
(socket_name_ssh): New variabel.
(handle_connections): Additional argument: listen_fd_ssh. Accept
connections on both sockets, call start_connection_thread_ssh for
connections on listen_fd_ssh.
(start_connection_thread_ssh): New function.
(cleanup_do): New functions, basically old cleanup function.
(cleanup): Call cleanup_do for socket_name and socket_name_ssh.
(server_socket_create): New function ...
(main): ... use it.
(main): Generate environment entries for ssh.
* query.c (start_pinentry): Accept CTRL being NULL.
* command-ssh.c (ssh_key_to_sexp_buffer): New argument: comment;
integrate into S-Exp.
(ssh_identity_register): New argument: comment; pass to
ssh_key_to_sexp_buffer().
(ssh_handler_add_identity): Pass comment to
ssh_identity_register().
(ssh_identity_register): Allocate description dynamically, insert
comment; new variable: description_length; removed variable: i.
(data_sign): Do not calculate key grip for integration in
description; removed variable: i.
* findkey.c (modify_description): New function.
(agent_key_from_file): New variables: comment, comment_sexp,
comment_length, desc_text_modified; extract comment from S-Exp,
pass modified version to unprotect().
* command-ssh.c: Use gcrypt memory allocators, use secure memory
where necessary.
