directaccess: add some commands to the directaccess list
Before this patch we had a limited list of commands in the directaccess list.
This patch adds about 20 commands to that list:
- all the read-only commands in core supporting a rev as an argument
- 'outgoing': since people can use 'outgoing' to know what is going to be
pushed, the output of hg outgoing should be consistent with to the output
of hg push and must therefore disallow directaccess since hg push forbids it.
