This patch uses mmap() to read /data/system/packages.list

This avoids depending on the size of a fixed static buffer
which may happen to be too short for systems with a lot of
packages installed.

Also avoids calling malloc() which we don't want to trust here
since run-as is a setuid program.

This patch increases the size of the internal buffer used by run-as
to store the content of /data/system/packages.list from 8KB to 64KB.

It has been reported that, on some systems, 8KB was too small. This
resulted in a truncated file being loaded, and the inability to debug
native applications properly (either because the application was not
found in the list, or because the tool reported a 'corrupted
installation' due to BAD_FORMAT issues when parsing the truncated

1f4d95296acf34a93128332441782a80c10845b4 03-Mar-2010 David 'Digit' Turner <digit@google.com> Add 'run-as' command implementation as set-uid program.

Typical usage is 'run-as <package-name> <command>' to run <command>
in the data directory, and the user id, of <package-name> if, and only
if <package-name> is the name of an installed and debuggable application.

This relies on the /data/system/packages.list file generated by the
PackageManager service.
