I've added explanatory comments to mzExtractRecursive because
that function will live on as a utility even after we move the
zip format related logic to libziparchive.

This is in preparation of replacing it with libziparchive and
providing shim wrappers.

* commit '99e084ca8012bc7af52ae2fb9e72ab7180177daf':
Remove dead/unused code and realign some of the comments to make it more cleaner and easier to read
Currently, the writeProcessFunction fails when
there are zero bytes to write, potentially returning
errno from a previous operation, or hanging
indefinitely while it waits for a >0 result on a
write of size 0. This happens when the output
file is intended to be zero bytes in size.

mzGetStoredEntry gives you a pointer and address to the data of a zip
entry, assuming that entry is stored rather than deflated.

Use intptr_t/uintptr_t to cast between pointer and int to allow
building with -Werror=pointer-to-int-cast and
Werror=int-to-pointer-cast turned on.
Cast to char* instead of unsigned int for pointer arithmetic.

Changes minzip and recovery's file signature verification to work on
memory regions, rather than files.
For packages which are regular files, install.cpp now mmap()s them
into memory and then passes the mapped memory to the verifier and to
the minzip library.
Support for files which are raw block maps (which will be used when we
have packages written to encrypted data partitions) is present but
largely untested so far.

minzip had some features that were used when reading APKs, but APK
handling now uses libziparchive instead of minzip. Remove these
unused functions.

Modify the OTA installer to understand SELinux filesystem labels.
We do this by introducing new set_perm2 / set_perm2_recursive
calls, which understand SELinux filesystem labels. These filesystem
labels are applied at the same time that we apply the
UID / GID / permission changes.
For compatibility, we preserve the behavior of the existing
set_perm / set_perm_recursive calls.
If the destination kernel doesn't support security labels, don't
fail. SELinux isn't enabled on all kernels.

Make minzip log only a count of files when extracting, not individual
filenames. Make patching only chatter about free space if there's not
enough and compact the other messages.
Only the last 8k of the recovery log gets uploaded; this makes it more
likely that we will get all of it.

Use of __inline__ by projects in bootable/* was causing problems with
clang. Following the BKM and replaced use of __inline__ with
__attribute((__gnu_inline)).

Extend minzip, recovery, and updater to set the security context on
files based on the file_contexts configuration included in the package.

Add a version of package_extract_file that returns the file data as
its return value (to be consumed by some other edify function that
expects to receive a bunch of binary data as an argument). Lets us
avoid having two copies of a big file in memory (extracting it into
/tmp, which is a ramdisk, and then having something load it into
memory) when doing things like radio updates.

Remove the memory alignment that mysteriously made OTA installs work,
in anticipation of a kernel that fixes the actual problem. Handle
EINTR properly.
In donut, OTA installation often encounters the write() system call
doing short writes -- which is legal but unexpected -- or failing with
ENOSPC when plenty of space is available. Passing aligned memory
buffers to write() appears to prevent (or at least reduce the
frequency) of these problems. b/1833052 has been filed to look at the
underlying problem, but this change aligns buffers we use with write()
so we can OTA for now (or see if this problem still occurs).
minzip fails if write() doesn't write all the data in one call.
Apparently this was good enough before, but it causes OTAs to fail all
the time now (maybe due to the recently-submitted kernel)? Change
code to attempt continuing after short writes.
