python/notmuch2: do not destroy messages owned by a query

Any messages retrieved from a query - either directly via
search_messages() or indirectly via thread objects - are owned by that
query. Retrieving the same message (i.e. corresponding to the same
message ID / database object) several times will always yield the same
C object.

The caller is allowed to destroy message objects owned by a query before
the query itself - which can save memory for long-lived queries.
However, that message must then never be retrieved again from that
query.

The python-notmuch2 bindings will currently destroy every message object
in Message._destroy(), which will lead to an invalid free if the same
message is then retrieved again. E.g. the following python program leads
to libtalloc abort()ing:

import notmuch2
db   = notmuch2.Database(mode = notmuch2.Database.MODE.READ_ONLY)
t    = next(db.threads('*'))
msgs = list(zip(t.toplevel(), t.toplevel()))
msgs = list(zip(t.toplevel(), t.toplevel()))

Fix this issue by creating a subclass of Message, which is used for
"standalone" message which have to be freed by the caller. Message class
is then used only for messages descended from a query, which do not need
to be freed by the caller.

lib: index PKCS7 SignedData parts

When we are indexing, we should treat SignedData parts the same way
that we treat a multipart object, indexing the wrapped part as a
distinct MIME object.

Unfortunately, this means doing some sort of cryptographic
verification whose results we throw away, because GMime doesn't offer
us any way to unwrap without doing signature verification.

I've opened https://github.com/jstedfast/gmime/issues/67 to request
the capability from GMime but for now, we'll just accept the
additional performance hit.

As we do this indexing, we also apply the "signed" tag, by analogy
with how we handle multipart/signed messages.  These days, that kind
of change should probably be done with a property instead, but that's
a different set of changes.  This one is just for consistency.

Note that we are currently *only* handling signedData parts, which are
basically clearsigned messages.  PKCS#7 parts can also be
envelopedData and authEnvelopedData (which are effectively encryption
layers), and compressedData (which afaict isn't implemented anywhere,
i've never encountered it).  We're laying the groundwork for indexing

smime: tests of X.509 certificate validity are known-broken on GMime < 3.2.7

tell it whether the certificate that signs a message has a valid User
ID or not.

If the User ID is not valid, then notmuch does not report the signer's
User ID to the user.  This means that the consumer of notmuch's
cryptographic summary of a message (or of its protected headers) can
be confident in relaying the reported identity to the user.

However, some versions of GMime before 3.2.7 cannot report Certificate
validity for X.509 certificates.  This is resolved upstream in GMime
at https://github.com/jstedfast/gmime/pull/90.

We adapt to this by marking tests of reported User IDs for
S/MIME-signed messages as known-broken if GMime is older than 3.2.7
and has not been patched.

If GMime >= 3.2.7 and certificate validity still doesn't work for
X.509 certs, then there has likely been a regression in GMime and we
should fail early, during ./configure.

The import process from the OpenSSL-preferred form (cert+secretkey) is

util: after gzgets(), Z_STREAM_END means EOF, not error

Context: I am compiling notmuch on OpenBSD which has a rather old zlib
1.2.3.  It seems that the behaviour of gzgets() changed slightly between
this version and more recent versions, but the manual does not reflect
that change.  Note that zlib's manual:
- does not specify which error code (Z_OK or Z_STREAM_END) is set when
  EOF is reached,
- does not indicate the meaning of Z_STREAM_END after gzgets(), but
  based on its meaning as a possible return value of inflate(), I would
  guess that it means EOF.

emacs: use def instead of initial-input for notmuch-show-browse-urls

This is the non-deprecated way to use completing-read. Additionally
the old use was broken when using ivy for completing-read. For user's
using completing-read-default they won't see the default URL now, but
if they hit enter it will be visited. Alternatively they can select
it with M-n.

From the completing-read documentation for initial-input:

 This feature is deprecated--it is best to pass nil for INITIAL-INPUT
 and supply the default value DEF instead.  The user can yank the
 default value into the minibuffer easily using M-n.

Additionally collection is now all urls, rather than all but the
first. I'm not sure why "(cdr urls)" was previously done.

emacs: introduce notmuch-search-by-tag

This is like notmuch-search-filter-by-tag, but creates a new search
rather than filtering the current search. We add this to
notmuch-common-keymap since this can be used by many contexts. We bind
to the key "t", which is the same key used by
notmuch-search-filter-by-tag in notmuch-search-mode-map. This is done
intentionally since the keybinding for notmuch-search-mode-map can be
seen as a specialization of creating a new search.

This change was motivated for use in "notmuch-hello". It is a more
convenient way to search a tag than expanding the list of all tags. I
also noticed many saved searches people use are simply tags.

arch-independent, because it builds and ships a shared object in

I welcome any suggested improvements to this packaging, but it appears

basic tests.
