tm_tags_find() relies on a sorted tags array to be passed in but in
tm_source_file_set_tag_arglist() we don't have a sorted array yet and
sorting it on demand seems more heavy than the alternative:
make tm_tags_find() search the array linear if the new flag is set.
This fixes a bug in the Python parser when assigning the argument list
of __init__() methods to their class' argument list which annoyed me
for years already.
Also add a test case for this.
CTags defines __unused__ and __printf__, which not only are reserved
identifiers, but actually are used by GNUC as arguments of the
__attribute__() extension. This used to work because no code seeing
those definitions was trying to use them as __attribute__() argument,
but a recent change in GLib made it use it in atomic operation, which
are used by the tagmanager, which itself includes the CTags header
defining those, leading to a weird build failure -- since __unused__
expanded to an unexpected value.
To fix this, rename CTag's __ununsed__ to UNUSED and __printf__ to
PRINTF.
Split ctags and tagmanager sources, as follows:
tagmanager/ctags: the parsers, more or less upstream CTags;
tagmanager/mio: local MIO library copy;
tagmanager/src: actual tagmanager sources.
