Trying to move the AVB footer on a sparse file will corrupt the sparse
format. Rather than implement this properly, for now, have the
copy_avb_footer() function gracefully fail by skipping the operation.

This fixes a bug introduced by I81b6bd984aad8f7ddec93ce74f4543e4f71be508
In the original CL, setting a sysprop `next_boot.<name>` and then
rebooting the device could remove all the persistent properties stored
in /data/property/persistent_properties. It happened because the
function `WritePersistentProperty` is called with a properties set which
is initialized as an empty set and then added with the properties which
had the next_boot prefix.
As a result...
Before the boot:
* persist.a = 1
* next_boot.b = 2
* next_boot.persist.c = 3
After the reboot:
* b = 2
* persist.c = 3
persist.a gets lost.
This change fixes the issue by populating properties set from the memory
and then save it to the file.

Test: do the following.
$ adb root
$ adb shell setprop persist.a 1
$ adb shell setprop next_boot.b 1
$ adb shell setprop next_boot.persist.c 1
$ adb reboot
$ adb shell getprop persist.a
1 // was (none) before this change
$ adb shell getprop b
1
$ adb shell getprop persist.c
1
$ adb reboot
$ adb shell getprop persist.a
1 // was (none) before this change
$ adb shell getprop b
// (none) because b isn't persisted. WAI.
$ adb shell getprop persist.c

While doing this, refactor the intercept code to be easier to understand.
The primary use case for this is to perform a parallel stack dump (both Java and native) for specific ANRs.
Add tests for all of the different intercept conditions.
Modify the tests to display the error message from the intercept
response if there is an error.

This SELinux option has been deprecated in the kernel since v5.7. In
v6.4, commit a7e4676e made any write to this file a no-op.
Since v4.4, the default value of 0 is set by the kernel. Skip the
setting of this value since we only support kernel >= 4.14.

Cow reader will store header v3 in memory. ReadCowHeader can remain
mostly unchanged since the cow prefix is the same.
header->prefix.header_size will then tell us if we're reading a v3 or v2
header. v3 header is strictly a superset of v2 header so we can read a
v2 header into a v3 struct.
Added a test case to test_v3 where we write a header using v2_writer and
ensure CowReader is able to read it.

Rather than split this into two binaries as we did for libsnapshot, this

bionic hard codes the PAGE_SIZE macro as 4096. This is going away as
Android begins to support larger page sizes.
trusty uses PAGE_SIZE to round up the allocation size of the DMA
buffers and mmap sizes. This is not explicitly needed since the kernel
will always give you a page-aligned and page-sized multiple allocation
when allocating a dmabuf or mmap-ing.
Remove this PAGE_SIZE usage from TrustyApp, app_fuzzer, coverage,
line-coverage, modulewrapper.
