In Android 10, libcutils is deprecating the hash functions. This
patchset moves to use the STL map to handle storing related
truetype objects.
This patchset moves the truetype functions to it's own static
class and moves the declarations to a header file. I also removed
statistics functions that were not called from anywhere.

This allows flame to boot TWRP. Still will need to work on
super partition for vendor and system access.
The plan will be to cherry-pick any updates to android-9.0
through gerrit.twrp.me to this branch as a WIP.
gr_clip was not calculating the correct values after the rotation
patch. Since gr_clip width and height instead of taking a second
pair of x,y coordinates, we cannot depend as much on the
ROTATION_X_DISP and ROTATION_Y_DISP macros. The simplest solution
was to call scissor with direct values in most cases.

* The existence of TW_ROTATION that implements this feature at the
level of calls to libpixelflinger API closely mirrors the existence of
ro.sf.hwrotation for surfaceflinger in LineageOS.
* A brute-force approach was previously attempted via the
BOARD_HAS_FLIPPED_SCREEN makefile flag. That code iterated over the
active display surface in a double-buffered setup, and performed a
"smart" memcpy from the UI drawing surface (gr_draw) onto the display
surface. The problem was that, without heavy loop optimizations, that
code could have never scaled for 90 and 270 degree rotation.
I tried and you could literally see the for loop with the naked eye
while the display surface was updating.
* That code is now gone, but support for BOARD_HAS_FLIPPED_SCREEN := true
is still there (now means TW_ROTATION := 180).
* This patch relies on the assumption that it is impossibly difficult
and non-portable to rotate whole framebuffer display surfaces, in a
way that is not dependent upon the graphics backend (adf, fbdev, drm,
overlay etc). Therefore, it identifies the rendering primitives that
the TWRP graphics stack exposes to the GUI application above, and
implements hwrotation inside each of those calls instead:
- gr_line(), gr_fill() - 2D geometric shapes (lines, rectangles)
- gr_blit() - graphical image resources
- gr_ttf_textExWH() - font rendering
- gr_fb_width(), gr_fb_height() - framebuffer resolution
* The gist is to keep the backend and framebuffer (dimensions, row size
etc) unchanged (because making changes there is asking for trouble),
but present an altogether different reality to the calling API,
according to the compile-time constant TW_ROTATION.
* All (x, y) API coordinates and shapes are transformed before being
actually rendered as (x_disp, y_disp) display coordinates.
* With TW_ROTATION := 90 or 270 you can turn a landscape device into
a portrait one, because the GUI is fooled by the reversed dimensions
reported by gr_fb_width() and gr_fb_height() and renders the UI as
for a different device.
* For blit and text rendering operations, figuring out the transformed
coordinates in display space is not enough, as the surfaces that are
to be rendered have to be rotated themselves. This is handled by
allocating an intermediary rotated surface on each rendering
operation (not ideal), so the code with the intermediary surface
is compiled out for the TW_ROTATION := 0 case.
* This is still not as bad as rotating the whole framebuffer though, and
on a msm8976 device the performance hit is not even noticeable (for
software rendering).
* Currently there is no attempt to make a connection between the
TW_ROTATION and the { RECOVERY_TOUCHSCREEN_SWAP_XY,
RECOVERY_TOUCHSCREEN_FLIP_X, RECOVERY_TOUCHSCREEN_FLIP_Y } settings.

While not all of these old build flags are active or implemented
yet (and they may not ever be implemeted until we find a device
that needs them), we need to make sure that the old build flags
are only applied when actually needed. Since there are a lot of
device trees that probably won't get updated due to lack of device
maintainers, we will rename the build flags and fix up devices on
a case by case basis.
Also added some pixel format related build flags to the make file
from AOSP so that AOSP devices should work in TWRP without
additional build flags.

Note: events.cpp is still old code renamed to cpp to make it
easier to call functions like gr_fb_width().
I had to modify AOSP fbdev code to provide a separate memory
surface for drawing to as drawing directly to the framebuffer
resulted in rendering taking about 5 times longer.
I also modified AOSP adf code to provide a separate memory surface
for drawing for the same performance reasons. The Nexus 9 supports
adf graphics.
Overlay graphics work on at least one device. Overlay provides a
separate memory buffer already so performance is good.
I do not have a drm device yet that I know of. I made some attempt
to update the drm code to determine the correct pixel format based
on the drm graphics format, but what is available in pixel flinger
and what is available in drm do not line up all that well. Reports
are that the Pixel C is using drm graphics, but performance is
slow, likely due to the use of a mmap instead of a memory buffyer.

This patch set removes support in TWRP for the old .dat file
format as well as support for the AOSP style fonts in header
files. We need TTF for scaling.
Note that the old AOSP style header font is still supported in
minui which is not used by TWRP.

In order to maintain compatibility with older trees, we now have
minadbd.old and minui.old. I had to use a TARGET_GLOBAL_CFLAG to
handle ifdef issues in minui/minui.d because healthd includes
minui/minui.h and there was no other alternative to make minui.h
compatible with older trees without having to modify healthd rules
which is outside of TWRP.
Note that the new minui does not currently have support for qcom
overlay graphics. Support for this graphics mode will likely be
added in a later patch set. If you are building in a 6.0 tree and
have a device that needs qcom overlay graphics, be warned, as off
mode charging may not work properly. A dead battery in this case
could potentially brick your device if it is unable to charge as
healthd handles charging duties.
Update rules for building toolbox and add rules for making toybox
Use permissive.sh in init.rc which will follow symlinks so we do
not have to worry about what binary is supplying the setenforce

Fixes touch on Oppo R7 Plus
Oppo R7 Plus, when recovery is flashed and booted from the actual
recovery partition, the digitizer sends some extra touch data for
up to 10 different touch slots even if no actual touch is present
for those slots (ABS_MT_SLOT). This patch allows TWRP to handle
touch data properly for this device and maybe others.
