67c3bc9db4 lib: Add some missing static qualifiers.
These various functions and data are all used only locally, so should
be marked static. Ensuring we get these right will avoid us accidentally
leaking unintended symbols through the library interface.

4dd066ae6c Update library version to 1.2.0
This increment is for the recently-added functions:

	notmuch_query_get_query_string
	notmuch_query_get_sort

These were recently added to the library interface, but the library
version was not incremented at that time, (shame on me).

f7a688ec53 Do not call ldconfig when building Debian package
Hi,

If I want to build Debian package, it fails with the following message:

    ldconfig: Can't create temporary cache file /etc/ld.so.cache~: Permission denied
    make[1]: *** [install-lib] Error 1

The reason is that I build the package as a non-root user and make
install invokes ldconfig unconditionally. The following patch contains a
workaround, but I think that a more correct solution would be to check
the condition LIBDIR_IN_LDCONFIG directly when make install is invoked
rather than in configure as it is done now.

threads object. Fix this to properly propagate the error.

029830c1f1 lib: Fix use-after-free bug.
Thanks to the new git-based test suite, it's easy to run the whole
test suite in valgrind, (simply "make test OPTIONS="--valgrind"), and
doing so showed this obvious use-after-free bug, (triggered by the
thread-order tests).

d64d0cc8d9 make install: Run ldconfig or install a DT_RUNPATH in binary as appropriate.
Various users were confused as to why they couldn't run notmuch
immediately after "make install", (with linker errors saying that
libnotmuch.so could not be found). The errors came from two different
causes:

1. The user had installed to a system library directory, but had not
   yet run ldconfig.

2. The user had installed to some non-system directory, and had not
   set the LD_LIBRARY_PATH variable.

With this change we fix both problems (on Linux) without the user
having to do anything additional. We first use ldconfig to find the
system library directories. If the user is installing to one of these,
then we run ldconfig as part of "make install".

For case (2) we use the -rpath and --enable-new-dtags linker options
to install a DT_RUNPATH entry in the binary. This entry tells the
dynamic linker where to find libnotmuch. Without the
--enable-new-dtags option only a DT_RPATH option would be installed,
(which has the drawback of not allowing any override with the
LD_LIBRARY_PATH variable).

Distributions (such as Debian and Fedora) don't want to see binaries
packaged with a DT_RPATH or DT_RUNPATH entry. This should be avoided
automatically as long as the packages install to standard locations,
(such as /usr/lib).

7b78eb4af6 Add support (and tests) for messages with really long message IDs.
Scott Henson reported an internal error that occurred when he tried to
add a message that referenced another message with a message ID well
over 300 characters in length. The bug here was running into a Xapian
limit for the length of metadata key names, (which is even more
restrictive than the Xapian limit for the length of terms).

We fix this by noticing long message ID values and instead using a
message ID of the form "notmuch-sha1-<sha1_sum_of_message_id>". That
is, we use SHA1 to generate a compressed, (but still unique), version
of the message ID.

We add support to the test suite to exercise this fix. The tests add a
message referencing the long message ID, then add the message with the
long message ID, then finally add another message referencing the long
ID. Each of these tests exercise different code paths where the
special handling is implemented.

A final test ensures that all three messages are stitched together
into a single thread---guaranteeing that the three code paths all act
consistently.

98845fdbb2 Avoid database corruption by not adding partially-constructed mail documents.
Previously we were using Xapian's add_document to allocate document ID
values for notmuch_message_t objects.  This had the drawback of adding
a partially constructed mail document to the database. If notmuch was
subsequently interrupted before fully populating this document, then
later runs would be quite confused when seeing the partial documents.

There are reports from the wild of people hitting internal errors of
the form "Message ... has no thread ID" for example, (which is
currently an unrecoverable error).

We fix this by manually allocating document IDs without adding
documents. With this change, we never call Xapian's add_document
method, but only replace_document with either the current document ID
of a message or a new one that we have allocated.

c210d5632e lib: Re-implement moving of thread authors.
Just before releasing 0.3 we received reports of crashes that were
bisected to the commit adding thread-author moving. Sure enough,
valgrind pointed to buffer overruns in _thread_move_matched_author.

Rather than trying to make sense of all the by strncpy, strchr, +1,
and +2 of that code, I reimplemented thread-author ordering with a
pair of hash tables and an array.

Valgrind is at least happy now on the test cases it was complaining
about previously.

5b8b0377cb Make Received: header special in notmuch_message_file_get_header
With this patch the Received: header becomes special in the way
we treat headers - this is the only header for which we concatenate
all the instances we find (instead of just returning the first one).

This will be used in the From guessing code for replies as we need to

good chance to guess which mailbox this email was delivered to.

26d8d960ee Reorder displayed names of thread authors
When displaying threads as result of a search it makes sense to list those
authors first who match the search. The matching authors are separated from the
non-matching ones with a '|' instead of a ','

Imagine the default "+inbox" query. Those mails in the thread that
match the query are actually "new" (whatever that means). And some
people seem to think that it would be much better to see those author
names first. For example, imagine a long and drawn out thread that once
was started by me; you have long read the older part of the thread and
removed the inbox tag. Whenever a new email comes in on this thread,
prior to this patch the author column in the search display will first show
"Dirk Hohndel" - I think it should first show the actual author(s) of the new
mail(s).

not used at the moment anywhere in the code.

36e4459a32 thread: Simplify code for assigning the subject.
We know that matched messages are always added in order, so we can
always just grab the subject from the first message. This is the same
approach that was used previously in _thread_add_message. That is, the
recent feature of renaming a thread based on the subject of the
"first" matched message is as simple as moving the subject assignment
from _thread_add_message to _thread_add_matched_message.

4971b85641 Name thread based on matching msgs instead of first msg.
At the moment all threads are named based on the name of the first message
in the thread. However, this can cause problems if people either start
new threads by replying-all (as unfortunately, many out there do) or
change the subject of their mails to reflect a shift in a thread on a
list.

This patch names threads based on (a) matches for the query, and (b) the
search order. If the search order is oldest-first (as in the default
inbox) it chooses the oldest matching message as the subject. If the
search order is newest-first it chooses the newest one.

Reply prefixes ("Re: ", "Aw: ", "Sv: ", "Vs: ") are ignored
(case-insensitively) so a Re: won't change the subject.

Note that this adds a "sort" argument to _notmuch_thread_create and
_thread_add_matched_message, so that when constructing the thread we can
be aware of the sort order.

c48dcc302c lib: search_threads: Fix nested search to handle original search of "*"
When constructing a thread, we usually run a nested query to find all
messages in the thread that match the original search string. However,
we need to have special-case handling of an original search string of
"*" now that that is a supported means of specifying all messages.

The special-case ends up bein quite simple---we do less work, (just
skipping the nested search since we know that all messages must
match). I had been wanting to write this identical code to more
efficiently handle "notmuch search thread:<foo>" which was previously
running two identical searches. So that case is now more efficient as
well.

When determining the thread id for a message we also check for this
