Two minor issues were fixed:
- The offset to entry data can be the same as the
central directory offset when the last entry in the
file has length 0 and is stored (not deflated). Fix
a check that disallowed this. We already have a strict
check that entry data must end before the central directory,
so we're covered.
- We would attempt to map a segment of length 0 when writing
an entry whose length is 0. We should just return early in
this case.

The issue here is that the makefile sets LOCAL_LDFLAGS
and asks for -llog without declaring a dependency on it.
This will cause build breakages if liblog hasn't already
been built yet.

Unlike ALOGV, messages from ALOGD are logged on
all configurations. Not finding an entry in a zip
file is a "normal" occurrence so using an ALOGD
message for it amounts to spam.

We would always write uncompressed data at offset 0 instead
of the current filedescriptor offset.
Also adds a unit-test & a clarifying comment on the API.

We don't need a warning if an entry isn't found in a zip
file. It can happen as part of normal operation.

- Add a build rule for host tests
- Add basic tests for Find / Iterate and Extract
for both deflated & stored entries.
- Fix an off by one error that the test uncovered.

Extract zip file processing logic from libdvm into a
standalone library.
This library is a stricter than the libdvm library in
several ways:
- Duplicate zip entry names are now disallowed. Files with
such entries will fail to parse.
- We now verify CD file size information with the individual
file header information. (This was pointed out as a deficiency
of this implementation in past discussions.)
- We also add support for crc checking, which means we might
need to parse the optional data descriptor footer (if one
exists).
We also provide an API for iterating over the entries of
a zip file. This library is optimized for two use cases :
- Lookup for a single entry in the file, with the intention
of processing or extracting the data associated with that
entry
- Iterating over all entries in a file *and* processing
/ extracting their data.
