ag/880725 modified ReadAtOffset to seek then read from the open
file descriptor. Previously pread64 was used to provide atomic
behaviour.
This causes races when multiple threads are trying to access data from
the file. This is supported, so this change reverts the relevant parts
of the above CL to restore the old behaviour.

Also use ReadFully to replace read, because read can
return reading bytes less than requested. And use
WriteFully to replace write.

This allows someone to stream the data out of a zip archive
instead of extracting to a file or to memory.
Included in this change is a small cleanup of the makefile.

The code does not handle an edge case where writing a compressed
image can overflow the avail_out data when doing a flush. Add a
loop to keep writing the data while deflate indicates that it doesn't
have enough space to write out the compressed data during the flush.

Take mod_date into account as well, and fixes the issue where
all entries had creation dates in 1979.

The ZipWriter implementation exposes a stateful interface that allows
bytes of data to be streamed in as they arrive. ZipEntries can be
compressed and/or aligned on a 32-bit boundary for mmapping at runtime.

Linking against both libziparchive-host and libz-host results in
libz loaded twice (because it is also linked statically in
libziparchive).

since the struct is now used for other purposes. Also add some
comparator functions to the struct to simplify zip_archive.cc.
This is a follow-up CL for f1d3d3b247.

The objective of fallocate call seems to be to
make sure that we have enough enough space left
in the disk to house the uncompressed file.
But, fallocate is only supported in the following
file systems:
btrfs, ext4, ocfs2, and xfs
Return error only when fallocate fails due to
lack of space. The immediate ftruncate call is
going to take of the majority of other errors.

We're already linking against libbase but we'll have to add
a libbase dependency to every target that includes libziparchive
as a STATIC_LIBRARY dependency, given that there's no way to
express that what we want (except by adding a LOCAL_WHOLE_STATIC_LIBRARY
dependency on libbase to libziparchive but that seems bad too)

There were crashes when android failed to extract
zip archives due to out of free space on disk, with stacks like:
#00 pc 00000000000156b0 /system/lib64/libc.so (memcpy+176)
#01 pc 000000000002e5b8 /system/lib64/libandroidfw.so

#03 pc 000000000002f5c8 /system/lib64/libandroidfw.so (ExtractEntryToFile+268)
#04 pc 00000000000287d8 /system/lib64/libandroidfw.so (android::ZipFileRO::\
uncompressEntry(void*, int) const+12)
Space for the file is now allocated using fallocate rather than
ftruncate, since ftruncate dont actually reserve space on disk. When writes
to the mmaped pointer fails to be realized due to out of space SIGBUS
is the result. With this change we make sure that there is space available
before mmaping the pointer.

libziparchive fails to iterate some bootanimation archives
reporting invalid offset error. This is caused by failure
to process a directory with one file
(when name_offset + file_name_length == cd_offset).

Nobody ever called acquire() so release() was always
equivalent to delete. Just use delete instead so that
people can use unique_ptr directly (or shared_ptr if
they really want refcounts).

Removed LOCAL_C_INCLUDES which are no longer necessary as zlib
now uses the LOCAL_EXPORT_C_INCLUDE_DIRS mechanism.
Removed a couple of redundant LOCAL_MODULE entries
Tested compiling some of the projects that make use of libziparchive
and libziparchive-host using a clean out dir with aosp_flounder-userdebug
aosp_arm-eng targets
