This allows to read but not write profiles from the G9.
The dpi mode sturct is a little different as the mouse only supports
symetrical dpi for x/y. Given the current naming a suffix of _sym
was the best I could come up with.
The G9 profile has some additional unknown bytes compared to the
others. Unfortunately the content of them varies for the 4 first
profiles and the last. So adding a default value for the like with
the G700 is not possible. For this reason I dropped implementing
the write part for now.
Something else to address is that this mouse only has 10 buttons
compared to the usual 13 that we have in PROFILE_NUM_BUTTONS. For
now I just hardcoded it in the profile and hidpp10_get_profile.
Same commit for hidpp20:
Previously, we would put a random address in the macro value, meaning we
lose the content of the macros.

Macros are somewhat properly parsed in hidpp10.
The driver, however, supports only key press/release and delays.

unknown3 in G700 is the constant string "LGS02". This string is a marker
for LGS to specify that the rest of the data is the names of the profiles
and macros.
SetPoint doesn't set those, so they are considered as metadata.
In libratbag, we will parse those properly and always set them, no matter
if the user used SetPoint or not.

The mouse accept them, so they are not invalid.
Only the profile directory seems to be checking for the CRC.

This prevents the M705 to shout that we need to set RATBAG_HIDPP10_DPI
and also allows the mice with only 1 profile to be configured.

The complexity when writing the profile to ROM at first allows:
- to prevent the user to temper with a non full profile
- in case of a USB failure (disconnect or loss of power for the batteries)
we don't use partially overwrite the profile.

To not have a giant patch that writes profiles to the HID++1.0 mice,
this first patch only convert the user profile into the actual data
that needs to be sent to the mouse.
We use hidpp_error to output it but no end user will ever see that
because it will be removed in a later commit.

The button mapping of the hid++ 2.0 devices is close to the one from
HID++ 1.0, but not entirely (1.0 have a size of 3 while and 2.0 a size
of 4).
The parsing was not clean, so reuse a the same logic than hidpp10.

The G500 uses only one bit in the usage code (thus the holes in the table).
So for the G500, RATBAG_BUTTON_ACTION_SPECIAL_RESOLUTION_CYCLE_UP is
the same as RATBAG_BUTTON_ACTION_SPECIAL_RESOLUTION_DOWN for instance.

Most should be fine, though I did not tested each key.
HID++ 1.0 and 2.0 use it now, though HID++ 2.0 needs refinments (only a u8
is used though we need a u16)

The G700 can use a wireless receiver too. It is close enough to the
normal Logitech Unifying receiver, but is truncated as it can not pair
multiple devices.
We currently don't treat it in the kernel as an Unifying device, and
so giving the device index of 0x00 fails as the device is actually on 0x01.
While there is no proper kernel solution (if there will ever be one),
allow to add a parameter in the hwdb to specify the device index.
We might need it for some other devices too, we will see.

If the crc is wrong, the device will ignore the page.
This technically multiply by 6 the time to access the device, but this is
because we do not cache anything currently in hidpp10.

Looks like the hid++ 1.0 devices are also using the same crc computation,

The command get_profile can either return an index in the directory (in
the page 0x01 of the memory) or an absolute address. If the address is
returned, it is unclear whether the directory is updated.
This commit also includes changes from Peter:
hidpp10: if the profile index exceeds the number of directory index, use 0
hidpp10: factor out directory fetching
hidpp10: use the profile directory only in hidpp10_get_profile

Each hidpp10 device should have a udev property named either
RATBAG_HIDPP10_DPI or RATBAG_HIDPP10_DPI_LIST. These properties ensure
that we know the mapping between the raw value of the dpi reported by the
mouse and the actual value.
Older devices (using the scheme 1 or 2 of hidpp10_get_current_resolution)
have to use the DPI_LIST to be able to map 0x80+.
Newer devices (using scheme 3) use the DPI setting with min, max, step.
