We can't add the ones that need a shared library because the
infrastructure doesn't work yet. (We also can't comment this in the file,
because there's no support for comments :-( .)

The libziparchive public headers that refer to `off64_t` also need the
Mac workaround.
In fastboot, there's a stray `lseek64` but since it's only for offset 0,
any kind of seek is fine.

A typedef to void* allows an implicit conversion from ZipArchiveHandle*
(or any other pointer type) to ZipArchiveHandle.

libcxx/include/__locale) have an old-style-cast.

Debugging memory allocations on the nexus launcher unveiled significant memory allocations for the hashatable used in libziparchive, ~1MB.
This is partly because of the ZipString struct storing an entry in the table. The struct stored a pointer to a string (on 64 bit, 8 bytes) and the length to read from that pointer, 2 bytes. Because of alignment, the structure consumed 16 bytes, wasting 6 bytes.
Now, we store entries in the hashtable as a ZipStringOffset. This new structure stores a 4 byte offset from a fixed location in the memory mapped file instead of the entire address, consuming 8 bytes with alignment.
Bug: 79416399
Test: Builds successfully and manual testing by opening launcher on Pixel 2 shows precisely 50% decrease in memory allocated for the hashtable. From 909312 bytes to 454656.

adbd has been built as a static executable since the same binary was
copied to the recovery partition where shared library is not supported.
However, since we now support shared library in the recovery partition,
adbd is built as a dynamic executable.
In addition, the dependency from adbd to libdebuggerd_handler is removed
as debuggerd is handled by the dynamic linker.
A few more modules in /system/core are marked as recovery_available:
true as they are transitive dependencies of the dynamic linker.
This change also includes ld.config.recovery.txt which is the linker
config file for the recovery mode. It is installed to /etc/ld.config.txt
and contains linker namespace config for the dynamic binaries under
/sbin.

Test: `adb reboot recovery; adb devices` shows the device ID
Test: Select 'mount /system' in the recovery mode, then `adb shell`.
$ lsof -p `pidof adbd` shows that libm.so, libc.so, etc. are loaded from
the /lib directory.

We need to (a) tell soong to copy our data and (b) automatically find
our data relative to our executable.
The real point of this is to be able to run these tests in APCT and
presubmit.

libziparchive is explicitly marked as double_loadable since it is one of the
(indirect) dependencies of the LLNDK library libvulkan
and at the same time the lib itself is marked as VNDK. Such lib can be
double loaded inside a vendor process.
Note: even without this change, the library is already capable of being
double loaded due to the dependency graph around it. This change is to
make it explicit so that double loading of a library is carefully
tracked and signed-off by the owner of the lib.

Fix failures in DataDescriptor related tests due to to a bad call to
SetZipString (undefined behaviour). Also fix a typo in the test for
invalid descriptors, we were asserting things on the wrong array.
