ui.paths: add a "pushurl" path option

Individual paths can now define a "pushurl" option. This option,
if present, will be used by "hg push" instead of the regular URL.

If this option is not defined, the normal URL is utilized by pushing.
This patch is therefore fully backwards compatible.

This feature is useful for deployments that have separate read-write
URLs from read-only URLs. For example, Mozilla utilizes
unauthenticated, read-only https:// URLs and authenticated, read-write
ssh:// URLs. Without this feature or the employ of extensions, a
separate named path must be defined to distinguish between these
endpoints. This works. However, it confuses people and other
extensions (such as remotenames) that map state back to names. The
separate URLs are logically identical, so being able to map them to
the same named entity makes sense.
