This is especially important for the mx780, so we can get rid of the
rude workaround we currently have in the driver for it.

Changes since v1:
- Just have profile enable/disable in ratbag-command
- Use bool instead of int
Changes since v2:
- Remove leftover function, whoops
- Fix leftover ints to bools
- Lots of style fixes
Make sure that there can only be one resolution marked
as default.
The previous code allowed to set multiple resolutions
as default. To clean up any bad state we allways loop
all other resolutions and unset the default if neccesary.
Only managed to notice then while working on enabling/disabling
profiles. Somewhere down the line the encoding we pass to
ratbag_utf8_to_enc() managed to get typoed, causing it to actually fail
and not show anything because of the iconv helpers not returning
negative error codes.
After learning that just using this mouse was not the greatest way of
figuring out whether or not the iconv helpers worked, I decided to
write a few simple tests to ensure silly things like this don't happen
again.
Changes since v1:
- fix indentation
- Fix year in copyright on test-iconv-helper.c
- Use an encoding that's definitely invalid for the
iconv_invalid_encoding test
- Add tests for a bunch of bad utf16le strings
- Add tests for converting emojis to/from utf16le. Just so we have some
actually multibyte characters in here.

Changes since v1:
- has_changed→dirty
Changes since v2:
- Change loop in gskill_commit_profiles(). Ended up being different then
what we needed for enabling/disabling profiles. Anyway, we also needed to
move around the call to gskill_reload_profile_data() so that we call it
only once per commit, not once per profile write.
Changes since v3:
- commit_profiles->commit
Almost all of the devices we've worked with here are the same: they have
some sort of profile on them, and if they don't (which is quite rare)
it's rather easy to simulate one in the driver. In fact basically all of
the device drivers in ratbag just update the profile and rewrite it on
calls to the write_resolution_dpi() and write_button() calls. This is
annoying since profile writes can take a good bit of time, and we're
wasting a lot of time with redundant profile writes that way.
During XDC this year, we came up with an idea that makes more sense: a
profile oriented API. Instead of having multiple entrypoints in the API
to writing and updating the profile we just cache all of the profile
changes until ratbag_device_commit_profiles() is called, at which point
we do a single set of writes for each profile and button that changed.
This has a lot of advantages:
- Where the profile is and is not written out to the device is now
explicit.
- Changing attributes of each profile won't result in any sort of delay
up until the library user commits the profiles, allowing us to avoid
hanging the application every time a simple attribute is changed.
- We can cut down on workarounds in drivers to cater to the previous
API.
Since this commit doesn't handle converting all of the device drivers
over to the new API, we also add a temporary wrapper for devices that
haven't yet been converted to this new API so that they're still usable.
Once all of the drivers have been converted to the new API, the wrapper
will be removed along with the internal driver API calls.

Changes since v1:
- has_changed→dirty
- Change namespace to LIBRATBAG_0.5.0
Changes since v2:
- Remove unneeded note about not setting dirty bit
- commit_profiles->commit
- Make FIXMEs more obvious
- Minor styling nitpicks
- Split up capability check fixes into seperate patch
This commit adds complete (with the exception of LEDs and a few other
small things) support for configuring the G.Skill Ripjaws MX780. So far
this has been tested on firmware versions 19 and 21, and both of them
seem to work perfectly with this.
Changes since v1:
- Lots of style fixes
- Remove reset hook, comment out with #if 0 in case of usage in the
future
- Add ret = -EAGAIN check in the loop in gskill_general_cmd()
- Explain why we wait longer then the spec says to in
gskill_general_cmd()
- Check that buf[0] is set to GSKILL_GENERAL_CMD in gskill_general_cmd()
- Add some notes as to why we don't use gskill_general_cmd() in
gskill_select_profile()
- Cleanup return codes, change gskill_general_cmd() so it only returns
valid error codes. In places not using gskill_general_cmd(), do
return rc < 0 ? rc : -EPROTO;
- Split command for selecting the macro to read/write from into it's own
function, just like we do with the profile
- Move profile count workaround into it's own function, make explicit
note of why it's needed
- Add proper support for reading/writing profile/macro names, ensure
they aren't left blank so as to not confuse G.Skill's software
- Use HID kbd modifier codes for translating macro kbd modifier codes
- Use AS_MASK instead of (1 << foo) (apparently we already had this :)

Some simple helpers to make converting strings to/from UTF-8 easier.
Required for the G.Skill driver since the profile/macro names are stored
in UTF16-LE on the mouse, and must be non-empty in order to prevent
confusing the default G.Skill config software.
Changes since v1:
- Fix potential erroneous free() if we fail to decide the target string
The new version is called "G502 Proteus Spectrum", so the older version comment is changed to "G502 Proteus Core" (its complete name) to avoid confusion.

The onboard profile do not store the current value but the default.
To retrieve the current value, we need to access the switchable resolution
feature.

A negative error means a communication error, while a positive one means
a HID++ one. Make sure we abort early enough.
