[Compress]Add some easy-to-use APIs for Zip and other archivers

[Peter Lee]

Hi all.

I'm thinking about adding some easy-to-use APIs for Zip. Currently I got
some ideas :
1. Add extractAll(String targetPath) in ZipFile : extract all the files to
the specific directory.
2. Add getInputStream(String fileName) in ZipFile : get the input stream
for a file by name.

And I believe these could also work in other archivers like tar, 7z and
some other format.

Do you think if this is a good idea or not?
