With the original quiet function, there's an actual purpose (hiding
excessively long compiler command lines so that warnings and errors
from the compiler can be seen).
But with things like quiet_symlink there's nothing quieter. In fact
"SYMLINK" is longer than "ln -sf". So all this is doing is hiding the
actual command from the user for no real benefit.
The only actual reason we implemented the quiet_* functions was to be
able to neatly right-align the command name and left-align the arguments.
Let's give up on that, and just left-align everything, simplifying the
Makefiles considerably. Now, the only instances of a captialized command
name in the output is if there's some actually shortening of the command
itself.
We add a magic line to the beginning of each Makefile.local file to
help the editor know that it should use makefile mode for editing the
file, (even though the filename isn't exactly "Makefile").

emacs/Makefile.local to each instance of Makefile.local.
The idea here is to allow a new user of notmuch to be able to run
notmuch immediately after compiling, (without having to install
the shared library first). This also ensures that the test suite
tests the locally compiled library, and not whatever installled
version of the library the dynamic linker happens to find.
When I wanted to create a debian package from the current master, make
install failed because of non-existent include directory. This patch
fixes this minor issue.
We had a fairly ugly violation of modularity with the top-level
Makefile.local isntalling everything, (even when the build commands
for the library were down in lib/Makefile.local).
We were previously maintaining two lists of the child Makefile
fragments---one for the includes and another for the dependencies. So,
of course, they drifted and the dependency list wasn't up to date.
We fix this by adding a single subdirs variable, and then using GNU
Makefile substitution to generate both the include and the dependency
lists.
Some side effect of this change caused the '=' assignment of the dir
variable to not work anymore. I'm not sure why that is, but using ':='
makes sense here and fixes the problem.
This new directory ojbect provides all the infrastructure needed to
detect when files or directories are deleted or renamed. There's still
code needed on top of this (within "notmuch new") to actually do that
detection.
Use the facilities of GNU make to create a magic function that will
on the first invocation print a description of how to enable verbose
compile lines and then print the quiet rule.

The new object is simply a linked-list of notmuch_message_t objects,
(unlike the old object which contained a couple of Xapian iterators).
This works now by the query code immediately iterator over all results
and creating notmuch_message_t objects for them, (rather than waiting
to create the objects until the notmuch_messages_get call as we did
earlier).
The point of this change is to allow other instances of lists of
messages, (such as in notmuch_thread_t), that are not directly related
to Xapian search results.
Previously, the top-level Makefile was explicitly adding -I./lib to
the compiler flags. However, that's something that's much better done
from within the Makefile.local fragment within the lib directory
itself.
I saw this recommendation in the implementation notes for "Recursive
Make Considered Harmful" and then the further recommendation for
implementing the idea in the GNU make manual.
The idea is that if any of the files change then we need to regenerate
the dependency file before we regenerate any targets.
The approach from the GNU make manual is simpler in that it just uses
a sed script to fix up the output of an extra invocation of the
compiler, (as opposed to the approach in the implementation notes from
the paper's author which use a wrapper script for the compiler that's
always invoked rather than the compiler itself).
The idea here is that every Makefile at each lower level will be an
identical, tiny file that simply defers to a top-level make.
Meanwhile, the Makefile.local file at each level is a Makefile snippet
to be included at the top-level into a large, flat Makefile. As such,
it needs to define its rules with the entire relative directory to
each file, (typically in $(dir)). The local files can also append to
variables such as SRCS and CLEAN for files to be analyzed for
dependencies and to be cleaned.
