The target buffer is 7 bytes long, null-termination is optional (as the comment
already suggests). Coverity is unhappy about this though so let's use memset and
memcpy instead.

xkb_keysym_from_name() is called a lot in Compose file parsing. The
lower case handling slows things down a lot (particularly given we can't
use the optimized strcasecmp() due to locale issues). So add separate
handling for the non-case-sensitive case which is used by Compose.
To do this we need to add another version of the ks_tables table. This
adds ~20kb to the shared library binary. We can probably do something
better here but I think it's fine.

Turns out FreeBSD supports evdev, so this toll can work on it; however
it does not support epoll, so switch to poll, which is portable.

libxkbcommon-1.0.3/src/xkbcomp/ast-build.c:526: leaked_storage: Variable "file"
going out of scope leaks the storage it points to.
Where we exit the loop early, we don't release the various allocated memory.
Make this patch more obvious my moving the declaration for those into the loop
as well, this way we know that they aren't used outside the loop anywhere.

False positive because we rely on xkb_components_from_rules() to initalize this

Both get_atom_name() and the new atom interner required a round trip. Move
get_atom_name() into the atom interner to save one more round trip. This brings
xkb_x11_keymap_new_from_device() down to two round trips, which is the minimum
possible number.
(Also, I think the new code in keymap.c is more readable than the mess I
previously created)
With this last commit in the series, this definitely:

There are a number of XKB requests needed to request all the information from
the X11 server. So far, the code was sending one request and waiting for the
reply. This commit starts batching the request so that we get multiple replies
with one round trip.
This removes three round trips.
Only the simple requests are converted. get_map() and get_names() use some
bitmasks that are needed for both the request and the reply. These will be dealt
with separately.

Instead of asking for an atom name and waiting for the reply four times, this
now sends four GetAtomName requests and waits for all the replies at once. Thus,
this saves three round trips.

On my system, calling xkb_x11_keymap_new_from_device() did 78 round trips to the
X11 server, which seems excessive. This commit brings this number down to about
9 to 10 round trips.
The existing functions adopt_atom() and adopt_atoms() guarantee that the atom
was adopted by the time they return. Thus, each call to these functions must do
a round-trip. However, none of the callers need this guarantee.
This commit makes "atom adopting" asynchronous: Only some time later is the atom
actually adopted. Until then, it is in some pending "limbo" state.
This actually fixes a TODO in the comments.

A simple script that creates a new layout with the given keysym replacing TLDE.
Then we compile a keymap and search for the keysym being assigned to TLDE and
bail if that fails.
The list of keysyms is manually maintained but we only need to add one or two to
spot-check whenever the xorgproto is updated.

As of xorgproto commit 5dbb5b76597f [1], the 0x10081XXX keycode range is defined
for direct evdev kernel keycode mapping. For example, KEY_MACRO1 (0x290) is
mapped to 0x10081290. The format of the #define lines for these keys is
stable to allow for parsing:
#define XF86XK_FooBar _EVDEVK(0x123) /* optional comment */
Update our script so we detect these new lines. Our keysym generation is a
two-step process: makeheader and then makekeys. Replacing the key with its full
value in the makeheader script means we don't have to update makekeys to handle
the _EVDEVK macro and our header file is fully resolved.

On every keymap notify event, the keymap should be refreshed, which
fetches the required X11 atoms. A big keymap might have a few hundred of
atoms.
A profile by a user has shown this *might* be slow when some intensive
amount of keymap activity is occurring. It might also be slow on a
remote X server.
While I'm not really sure this is the actual bottleneck, caching the
atoms is easy enough and only needs a couple kb of memory, so do that.

Before: retrieved 2500 keymaps from X in 11.233237s

Where resolve_keysym fails we warn but use the otherwise uninitialized variable
as our keysym. That later ends up in the keymap as random garbage hex value.
Simplest test case, set this in the 'us' keymap:
key <TLDE> { [ xyz ] };
And without this patch we get random garbage:
./build/xkbcli-compile-keymap --layout us | grep TLDE:
key <TLDE> { [ 0x018a5cf0 ] };
With this patch, we now get NoSymbol:
./build/xkbcli-compile-keymap --layout us | grep TLDE:
key <TLDE> { [ NoSymbol ] };
