Thanks to everyone for their reviews of this series that provides
indexing of the cleartext of encrypted messages (and thanks to bremner
for already pushing some of the less controversial patches of the
previous revisions of this series).  I hope you'll agree that your
suggestions have improved the propsoal :)

In particular, the following significant changes have been made since
the previous revision:

 * all properties whose key is prefixed with "index." are cleared (and
   possibly re-set) upon reindexing, not just a registered list of
   "autoproperties".

 * handling of command-line options for indexing (i.e. for the "new",
   "reindex", and "insert" subcommands) has been consolidated into a
   centralized location, which not only reduces total code footprint
   but will make it easier to add shared indexing options in the
   future.

I welcome review and feedback.

This prepares us for using the crypto object in both libnotmuch and
the client.

If we're going to reuse the crypto code across both the library and
the client, then it needs to report error states properly and not
write to stderr.

This is currently mostly a wrapper around _notmuch_crypto_t that keeps
its internals private and doesn't expose any of the GMime API.
However, non-crypto indexing options might also be added later
(e.g. filters or other transformations).

Subsequent patches will introduce a convention that properties whose
name starts with "index." will be stripped (and possibly re-added)
during re-indexing.  This patch lays the groundwork for doing that.

This allows us to create new properties that will be automatically set
during indexing, and cleared during re-indexing, just by choice of
property name.

If we see index options that ask us to decrypt when indexing a
message, and we encounter an encrypted part, we'll try to descend into
it.

If we can decrypt, we add the property index.decryption=success.

If we can't decrypt (or recognize the encrypted type of mail), we add
the property index.decryption=failure.

Note that a single message may have both values of the
"index-decryption" property: "success" and "failure".  For example,
consider a message that includes multiple layers of encryption.  If we
manage to decrypt the outer layer ("index.decryption=success"), but
fail on the inner layer ("index.decryption=failure").

Because of the property name, this will be automatically cleared (and
possibly re-set) during re-indexing.  This means it will subsequently
correspond to the actual semantics of the stored index.

At indexing time, the database needs to know its internal defaults.
It shouldn't be contingent on an external config file (since that
can't be retrieved from the database object itself).

This behaves the same as the query.* configurations, which are also
stored in the database itself, so we're not introducing any new
dependencies.

By default, notmuch won't try to decrypt on indexing.  With this
patch, we make it possible to indicate a per-database preference using
the config variable "index.try_decrypt", which by default will be
false.

We have an indexopts structure for manipulating indexing in different
ways, but we also have three command-line invocations that can trigger
indexing: new, insert, and reindex.

This changeset prepares a common parser that these subcommands can
share.

At the moment, it's just --try-decrypt, but others will likely follow.

Try to decrypt any encrypted parts of newly-discovered messages while
indexing them.  The cleartext of any successfully-decrypted messages
will be indexed, with tags applied in the same form as from notmuch
insert --try-decrypt=true.

Note: if the deprecated crypto.gpg_path configuration option is set to
anything other than "gpg", we ignore it (and print a warning on
stderr, if built against gmime < 3.0).

We also add a new test making use of this functionality.  This
requires a bit of reorganization, because we need to allow passing
--long-arguments to "notmuch new" via emacs_fcc_message

Allow an incoming message to be delivered while indexing the
cleartext, on a per-message basis.

This requires the secret keys for the message to be available.  For
the moment, the most functional approach is to ensure that gpg-agent
is running and knows about any secret keys that might be useful to
decrypt incoming mail.

Any additional recommendations for how to phrase the caveat for this
option are welcome.

Note: if the deprecated crypto.gpg_path is set to anything other than
"gpg", we ignore it (and print a warning on stderr, if built against
gmime < 3.0).

I have reviewed this patch series and everything looks in order.  Coding
style is consistent with notmuch standards.  The patch is
feature-complete, with appropriate documentation.  All tests pass.  I am
now using this series by default, with config set to automatically index
encrypted mail ("index.try_decrypt=true"), and have experienced no
issues.

I am strongly in support of this patch series.  Daniel is doing crucial
work pushing for widespread use of email encryption.  This series is
necessary in the context of that larger goal.  He's been pushing this
series for a year and a half now, so I think it's appropriate that it
final be integrated.

jamie.
