* scd/command.c (send_status_info): Bump up N.
--

This fixes a potential overflow if LFs are passed to the status
string functions.  This is actually not the case and would be wrong
because neither the truncating in libassuan or our escaping is not the
Right Thing.  In any case the functions need to be more robust and
comply to the promised interface.  Thus the code has been factored out
to a helper function and N has been bumped up correctly and checked in
all cases.

For some uses this changes the behaviour in the error case (i.e. CR or
LF passed): It will now always be C-escaped and not passed to
libassuan which would truncate the line at the first LF.

  with clearer text.

In standard English, the normal construction is "${XXX} allows ${YYY}
to" -- that is, the subject (${XXX}) of the sentence is allowing the
object (${YYY}) to do something.  When the object is missing, the
phrasing sounds awkward, even if the object is implied by context.
There's almost always a better construction that isn't as awkward.

These changes should make the language a bit clearer.

g10: Add openpgp_protected flag to agent secret key export functions
* g10/call-agent.c, g10/call-agent.h (agent_export_key): Add
openpgp_protected flag.
* g10/export.c (receive_seckey_from_agent): Request openpgp_protected
secret keys from agent.
* agent/command.c (hlp_export_key): EXPORT_KEY help text: add a
brief description of the effect of --openpgp.
--

The --openpgp flag for gpg-agent's EXPORT_KEY actually forces
encryption in a certain (RFC 4880-compatible format).  This changeset
exposes that functionality in internal functions, and clarifies
functionality in the agent's help text.

Unless the agent has been configured with

is now possible with gpg by using --batch _and_ --yes.

Instead of using the old OpenPGP way of appending a hash of the
plaintext and encrypt that along with the plaintext, the new scheme
uses a proper authenticated encryption mode.  See keyformat.txt for a
description.  Libgcrypt 1.7 is required.

This mode is not yet enabled because there would be no way to return
to an older GnuPG version.  To test the new scheme use
gpg-protect-tool:

 ./gpg-protect-tool -av -P abc -p --debug-use-ocb <plain.key >prot.key
 ./gpg-protect-tool -av -P abc -u <prot.key

Any key from the private key storage should work.
