webapi: remove 'mkdir-p' API since it logs pathnames

[warner]

We did a pass through the HTTP logging in webish.py to make sure that no pathnames or other sensitive data is recorded in the logs. The mkdir-p call got added after this pass, and needs to be fixed to not record that information.

[warner]

Changing the API to be POST /uri/$ROOT/path/to/be/made?t=mkdir would take care of this automatically, since we currently censor everything between /uri and the question mark. But I think the current API is more like POST /uri/$ROOT?t=mkdir-p&path=/path/to/be/made.

Milestone 1.0.1 deleted

[warner]

I added the new API: POST /uri/$ROOT/path/to/be/made?t=mkdir . I think the only user of the old API is the allmydata migration process, so once that is complete we can remove the t=mkdir-p API and documentation altogether.

I reviewed eb2a4ef24611f3bc and didn't see any problem with it.

This API is removed on the 1.9.2 branch: [5462/1.9.2]. Since there are no references to it in the source or docs and since we don't want to encourage its use, I decided this was safe even for a point release.
