I don't like hearing the WRRRRRRRRRRRRRRRRRRRRRRRRR of the fans and drives in my nas spinning up every time a build finishes

when the file `~/.divested.vars.${BDEVICE}` exists it get
sourced after the default variables set by init.sh.
so to make use of this you have to
`export BDEVICE=hotdog`
before `source ../Scripts/init.sh`. Then the file `~/.divested.vars.hotdog` will
be sourced - if existent.
this way one can:
- override defaults without touching the init.sh (makes git pull more convenient)
- set different settings for different devices

- Enable APEX for Pixel 6/7, necessary for camera and pKVM
- Also drop hack removing pKVM for Pixel 6/7
- patch from GrapheneOS
- Extend hmalloc workaround to /apex
- Deblobber:
- actually handle wildcard f/w/b overlays
- move some stuff around
- remove some more Pixel blobs
- flag and disable removal of camera extensions, being able to use the second camera is nice
- Adjust what hardenDefconfig disables, caused boot issues
minimal impact as most of these are already default-disabled
can be narrowed down in future
- Disable some of the bionic hardening patches, causing more boot issues
annoying to lose, but having a phone that boots is more important
- Add LTE only mode to 17.1, 18.1, 19.1, and 20.0, credit GrapheneOS
- Remove Pixel 2 ramdisk compression reverts, fixed upstream
And yes, I know I should've split up this commit...

Disabling extended sizes classes does not appear to have the savings it does on desktop.
Disabling the quarantine isn't acceptable given that default scudo implements it
This should help 64-bit devices with <4GB RAM substantially, at reduced hardening.
clark for example only has 2.5GB of usable memory and idles at 1.6GB used.
After this change, idle usage drops to 1.1GB!

I've triple checked that calls/data work fine without these blobs
and also have another report from walleye as the same.
I have no idea what is happening to those who have SIM issues.
This reverts commit dc392b17b6.
These were previously removed, and added back after a false report of breakage.
Data and VoLTE tested working on taimen

Change the property too, so it takes effect next update.
Since 16.0 lacks a toggle, this effectively disables the feature for it.
Even devices with 4GB of RAM have usability severely impacted.
Plus some other tweaks/churn

- Turns out AVB was set permissive this entire time :(
--flags 2 == VERIFICATION_DISABLED
- APEX support from GrapheneOS
- Disable vbmeta chaining like GrapheneOS
and optionally handle it like CalyxOS
taimen 19.1 boots with locked bootloader successfully after this

This ensures init_on_alloc/free is used instead of page poisioning where available.
3.4 through 3.18 have a patch without a toggle for page sanitization.

Adds ptrace_scope and timeout options to 17.1, tested working
Also adds hardened_malloc to 15.1, but failing to compile:

10+4 devices tested working with bionic hardening patches enabled
but hammerhead and shamu do not boot...
2 of the patches were already found to have issues and disabled
3 other patches were ruled out:
- Stop implicitly marking mappings as mergeable
- Make __stack_chk_guard read-only at runtime
- On 64-bit, zero the leading stack canary byte
Leaves 11+1 patches remaining that need to be tested
But I don't have either of the two known impacted devices.

- enable the patchset for 18.1
- add an ugly patch that extends the Pixel 3* camera workaround to all camera executables
