Set and restore PR_SET_DUMPABLE when performing a dump, so that
processes that have it implicitly cleared (e.g. services that acquire
filesystem capabilities) still get crash dumps.

Raise CapInh and CapAmb after forking to exec crash_dump, so that it
can ptrace us.

* changes:
init: fstab: add support to read fstab entries from device tree
init: early_mount: add support to mount non-verity partitions early
init: remove the existing early_mount code
init: refactor: add support for doing early coldboot
ueventd: make selinux labeling optional for device creation
waitpid(..., __WCLONE) fails with ECHILD when passed an explicit PID to
wait for. __WALL and __WCLONE don't seem to be necessary when waiting
for a specific pid, so just pass 0 in the flags instead.

Tests running in app context can't access /data/local/tmp,
so try current directory if /data/local/tmp is not accessible.

Use this for bootstat and init. This replaces the custom uptime parser in
bootstat.
This is a reland of aosp/332854 with a fix for Darwin.

This allows reliable use of larger buffer sizes.
Max r/w size is set only when that preallocation
is successful so that memory is guaranteed to be
available.

ubsan doesn't like us incrementing std::string::npos, even if we won't use

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
adding aforementioned DT node and enable CONFIG_PROC_DEVICETREE in kernel

This is done by parsing 'androidboot.fstab=<fstab>' kernel cmdline
option to get the fstab file that *only* specifies partitions to be
mounted early (i.e. in init's first stage).
Note that, the same fstab file may not be used as an argument to
mount_all later in the boot as that will cause fs_mgr to fail with
EBUSY.
TODO:
- Possibly add a new mount_mode so the same fstab can be used for
early_mount, 'mount_all --early/--late' etc.
- Add support for dm-verity enabled partitions to mount early.
- Add support for getting fstab arguments through DT instead of kernel
cmdline.
Bug: 27805372
Test:
Boot angler by passing a seperate fstab file using the kernel
cmdline option to mount vendor partition early, remove the vendor
partition entry from the main fstab file for the test.
Boot sailfish by passing a seperate fstab entry via device tree
to mount vendor partition early. Remove vendor partition entry from
the main fstab file for the test

Make libbacktraceoffline thread-safe by protecting the global variable with
a lock. So it can be used in a multi-thread environment, like by
simpleperf inplace sampling.

1. In /system/lib/libart.so, the ranges of functions covered by .eh_frame
and .ARM.exidx overlap with each other. Currently, we don't check .eh_frame
if the address is in the ranges of functions covered by .ARM.exidx. It leads
to a wrong unwinding result. So change the logic to first try .eh_frame and
.debug_frame, if it fails, then try .ARM.exidx.
2. Add test for Item 1.
