d957494d45 kext: even more perf improvements 
Turns out the undef handler path is quite hot, as only one thread per core can have VFP enabled at a time.

ef842dda2a Fix extremely obnoxious race-cond+uninit handle bug 
This is mostly a libctru bug (well, sort of).

This can only happen to built-in sysmodules, and to
processes waiting for err:f, that fail to obtain
handles through svcConnectToPort first try; and only
prior to 11.0.

Prior to fw 11.0, kernel didn't zero-initialize output
handles, and thus the output handle gets filled with
junk (leaked kernel stack data) in case of failure.
Libctru does not account for this, and closes such
handles anyway (in srvInit, errfInit, and possibly
more).

The problem is that, in our case, that garbage was
equal to 0x8000, actually a valid handle, in fact
the first handle to be created (and not closed) in
a process... a handle to KAddressArbiter.

Accidentally closing this handle resulted in one or
more KIPs spin-waiting and starving core1, resulting
in an inability to boot.

We fix this simply by replicating what recent k11 does,
in kext (for svcConnectToPort). For srvGetServiceHandle,
add two layers of safety.

- Add support for saving screen filters color temperature and NTP timezone offset (you still need to go to misc->save config)
- some advanced options moved to "in ini file only"; "patch games" is now enabled by default
- ntp: fix support for UTC+12 to +14
- remove deprecated custom svc 0x2e

adda19ecb2 so bascially rosalina's image...
