Most of this hinges on the --upload option being passed, and it never is
any more. Much of it also uses Google Buckets, which we no longer use,
save for some GCE-specific bits.

This is some fallout from converting scripts from python2 to
python3. Output received from the functions in subprocess module now
return bytearrays, but we operate on them as if they were a text. So
decode the bytearrays to strings. Otherwise we are either getting some
junk values passed to the command line utilities (for example:
`b'/dev/loop2'` instead of `/dev/loop2`), or exceptions are thrown,
because a function expected a string.
This is just a conversion done by 2to3 with a manual updates of
shebangs to mention python3 explicitly. The fixups for bytearray vs
string issues will follow up.
To be able to support arm64 native SDK without cross builds, we should
make generate_au_zip support both architectures, amd64 and arm64.
Without doing that, `build_image` fails with `ERROR : Required
WHITE_LIST items ld-linux-x86-64.so.2 not found!!!`, because the
script recognizes only amd64 libs in WHITE_LIST.
We should first determine the architecture in build_image, before
running generate_au_zip, and pass the architecture, either amd64 or
arm64. Also add allow_list and ld_linux parameters to necessary
functions.
A number of places refer to these paths and that number is going to
grow. Since the standard pattern is to use environment variables for
commonly used paths it is time to add ones for these:
REPO_CACHE_DIR
REPO_MANIFESTS_DIR
Add core_upload_update to au-generator.zip which requires some extra
logic to make it runnable anywhere it may be. To organize the code a
little better all the delta_generator calls have been moved to
cros_generate_update_payload. core_upload_update is now just a wrapper
around cros_generate_update_payload and core-admin.
Cgpt was moved and a symlink based wrapper was added. That wrapper will
be improved soon, when when that's true we'll need to change this back.
A specific note... cgpt is currently statically linked. If that wrapper does
not remain statically linked, then a simple revert won't be enough.

The new glibc caused a series of problems with Paygen based delta generation.
First, the new glibc is newer than what is used in workstations, or on
the Paygen servers. Since libc wasn't one of the libraries bundled up
by generate_au_zip.py, the executables bundled up (including delta_generator)
would fail because of unstatisfied library requirements at startup.
When the new libc was included by generate_au_zip.py, the delta_generator
executable started causing the dynamic loader to segfault during startup,
presumably because it was linked for a newer version. This means that
the new loader needs to be bundled and explicitly used when invoking
the new executables (thanks David James for figuring this out!).
Next, after including all of the new libraries, bash would crash at startup
with these libraries at the start of LD_LIBRARY_PATH. Since Paygen which
set LD_LIBRARY_PATH before invoking a shell script which invokes the delta
generator, this means delta generation would crash before it started.
If I modified Paygen to not set LD_LIBRARY_PATH, then older au_generator.zip
files could not be properly handled (and we do so regularly).
This change moves the required dynamic libraries into a subdir of the zip
file which will not be in Paygens LD_LIBRARY_PATH which allows bash to
operate correctly.
It also renames each dynamically linked executable from xxx to xxx.wrapped
and creates a shell script named xxx which invokes xxx.wrapped with the
new LD_LIBRARY_PATH and using ld-linux-x86-64.so.2 to do so.
This change also moves a number of constants from inline in various
functions to constants at the top of the script, and introduces a WHITE_LIST
to cause a build failure if ld-linux-x86-64.so.2 isn't present.
(Fixing chromium-os:32550 would help with that)

We were blacklisting some dependant libraries for the delta generator when
we bundle them all up together. When glibc in the chroot was update to be
newer than glibc on our workstations, this broke payload generation.
The real fix is to link delta_generator statically so we don't have to do
this goofy library bundling business (chromium-os:32544). In the mean time,
bundle everything up to get us working again.
