Treble allows framework-only (system.img) OTA. To libavb statically
linked in init/fs_mgr cannot parse the AVB metadata of system.img, add
this property for the Treble OTA match process.
Bug: 35236019
Test: Normal boots, use 'adb shell getprop' to check the property is set.
Test: Recovery boots, press 'Mount system' and use 'adb shell getprop'
to check the property is set

snprintf isn't safe to call in the linker after initialization, because
it uses MB_CUR_MAX which is implemented via pthread_getspecific, which
uses TLS slots shared with libc. If the TLS slots are assigned in a
different order between libc.so and the linker, MB_CUR_MAX will
evaluate to an incorrect value, and lead to snprintf doing bad things.
Switch to __libc_format_buffer.

adf_{device,interface_simple}_post_v2 let the client choose what kind of
fence is returned from the kernel:
* ADF_COMPLETE_FENCE_NONE: no fence is returned
* ADF_COMPLETE_FENCE_PRESENT: the returned fence fires when the
specified configuration appears on the screen
* ADF_COMPLETE_FENCE_RELEASE: the returned fence fires when the
specified configuration is removed from the screen
The "V2" calls with fence type ADF_COMPLETE_FENCE_RELEASE are functionally
equivalent to "V1" calls.
Test: included gtest (on Nexus 9)

waitpid(..., __WCLONE) fails with ECHILD when passed an explicit PID to

for a specific pid, so just pass 0 in the flags instead.

for early mount, we need a way to tell init where to find vendor,
odm partitions (also system in case of non-A/B devices). Also, that
needs to be independent of kernel cmdline since the cmdline will likely
exceed its limit.
The change adds support for parse and create fstab entries that can be
directly sent to the fs_mgr for mounting partitions early in init first
stage.
Sample DT entry to mount vendor partition early on angler-
firmware {
android {
compatible = "android,firmware";
fstab {
compatible = "android,fstab";
vendor {
compatible = "android,vendor";
dev = "/dev/block/platform/soc.0/f9824900.sdhci/by-name/vendor";
type = "ext4";
mnt_flags = "ro,barrier=1,inode_readahead_blks=8";
fsmgr_flags = "wait";
};
};
};
};

Test: Boot angler and sailfish with early "vendor" partition mount by
