Update Android port

* configure.ac: Take option `--with-shared-user-id' and give it
to AndroidManifest.xml.in.
* java/AndroidManifest.xml.in: Substitute that into the
application info.
* java/INSTALL (BUILDING WITH A SHARED USER ID): New section.

If you are building an Emacs package for redistribution, we urge you
to provide both debug and release versions.
BUILDING WITH A SHARED USER ID
Sometimes it may be desirable to build Emacs so that it is able to
access executables from another program. To achieve this, that other
program must have a ``shared user ID'', and be signed with the same
signing key used to sign Emacs (normally `emacs.keystore'.)
Once you have both that signing key and its ``shared user ID'', you
can give it to configure:
./configure --with-shared-user-id=MY.SHARED.USER.ID
Don't do this if you already have Emacs installed with a different
shared user ID, as the system does not allow programs to change their
user IDs after being installed.
