Jeff Brown 00c0cd4a24 Clean entire arg block when setting process name. 
When Android processes fork from Zygote, we rewrite the command line
with a new name, eg. "system_server".  When we do this, we should
fill the entire block with zeros to remove corrupted argument
information that may otherwise remain in the /proc/<pid>/cmdline buffer
and be seen in tools and stack dumps.

Fixed an issue where VM options could be overwritten after setting
the nice name if the name was too long.
