Use explicit labels for GTypeInfo member initializers, rather than
relying on comments and ordering. This is both easier to read, and
harder to screw up. This also makes it clear that we're mis-casting
GObject class initializers for gcc.
Without this patch, g++ 8.2.0-7 produces this warning:
CXX -g -O2 lib/index.o
lib/index.cc: In function ‘GMimeFilter* notmuch_filter_discard_non_term_new(GMimeContentType*)’:
lib/index.cc:252:23: warning: cast between incompatible function types from ‘void (*)(NotmuchFilterDiscardNonTermClass*)’ {aka ‘void (*)(_NotmuchFilterDiscardNonTermClass*)’} to ‘GClassInitFunc’ {aka ‘void (*)(void*, void*)’} [-Wcast-function-type]
(GClassInitFunc) notmuch_filter_discard_non_term_class_init,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The definition of GClassInitFunc in
/usr/include/glib-2.0/gobject/gtype.h suggests that this function will
always be called with the class_data member of the GTypeInfo. We set
that value to NULL in both GObject definitions in notmuch. So we mark
it as explicitly unused.
There is no functional change here, just code cleanup.
C99 stdbool turned 18 this year. There really is no reason to use our
own, except in the library interface for backward
compatibility. Convert the cli and test binaries to stdbool.
'g_object_newv' is deprecated, and prints annoying warnings. The
warnings suggest using 'g_object_new_with_properties', but that's only
available since glib 2.55 (i.e. a month ago as of this writing).
Since we don't actuall pass any properties, it seems we can just call
'g_object_new'.

Keith wrote all the code here against notmuch before notmuch.c was
split up into multiple files. So I've pushed the code around in
various ways to match the new code structure, but have generally tried
to avoid making any changes to the behavior of the code.
I did fix one bug---a missing call to g_mime_stream_file_set_owner in
show_part which would cause "notmuch show" to go off into the weeds
when trying to show multiple messages, (since the first stream would
fclose stdout).
